Native North American slippers include:

Cypripedium acaule (sip'ree-pea'dee-um a-call'ee). Habitat Minnesota. Blooms late spring. Flowers large; sepals and petals dark red-purple; lip veined rose-red. State flower.

C. CaHfomicum. (cal-i-forn'i-cum). Habitat California Mountains. Blooms summer. Flowers yellow and brown; lip white, flushed and spotted brown.

C. candidum (can'di-dum). Habitat eastern North America. Blooms May to June. Flowers small, bright green with an overtone of brown: lip white, with an inner pink flush.

C. parviflorum (par-vi-flor'um). Habitat eastern North America, as far north as Newfoundland and as far south as Georgia. Blooms May to June. Flowers brown with golden-yellow lip. Fragrant.

C. pubescens (pew-bess'ens). Habitat eastern North America. Blooms May to June. Flowers fairly large, greenish-brown; with a yellow-green lip, often softly flushed.

C. spectabile (speck-tab'ill-eh), sometimes called Reginae (re-gen'eye). Habitat eastern North America, as far north as Canada and as far south as North Carolina. Blooms May to June.

Flowers handsome and large, pale pink; darker rose lip with brighter spots. The beauty and charm of the species make a trip to their habitat one of delightful discovery. However, for the most part they do not survive transplanting and perish after a year or two. It is better to enjoy them in their swampy marshes and meadows.

The following are mottled-leaved species and require hot-house culture:

C. barbatum (bar-ba'tum). Habitat India and the Malay Peninsula. Blooms February to August. Flowers have broad dorsal, white with purple and green stripes; purple petals with a row of dark, hairy, warty excrescences, and a brown slipper pouch.

C. bellatulum (bel-lat-yeu'lum). Habitat Siam. Blooms spring. Plant very dwarf, having creamy-ivory flowers shell-shaped, heavily spotted with dull, dark purple.

C. callosum (cal-low'sum). Habitat Siam and China. Blooms March to July. Large handsome flowers with white dorsal shading into green and flushed at the base with purple, and marked dark crimson; petals pale green shading into purple; lip brown-purple.

One of the parents of C. Maudiae (C. callosum var. Sanderae x Lawrenceanum var. Hyeanum), a regal alba hybrid with glistening white dorsal, veined pale green; pale-green petals and pouch.

C. Fairriaenum (fair-i-an'um). Habitat Assam. Blooms July to September. Dwarf plant with small graceful dainty flowers having broad, greenish-white dorsal heavily lined with purple; curved white petals striped and margined with purple; and large brownish-green lip with purple network of veins.

The following lack the markings in the leaves and grow in cooler regions, and so require cool house conditions:

C. insigne (in-sig'nee). Habitat Assam. Blooms October to March. Favorite with amateurs, being prolific and easy to grow. Flowers medium with brown, shaded-green dorsal, dotted with brown-purple, and white at the apex; petals yellow-green, shaded brown-purple; lip similar. A fine parent,

C. Leeanum (lee-an'um) being one of its prominent and popular prog¬eny. Has many fine varieties of which Harefield Hall is outstanding; var. Sanderae. Primrose-yellow with the upper half of the dorsal white; var. Sanderianum. Considered the true albino, with dorsal colored white and petals and pouch chartreuse.

C. Leeanum (C. insigne x Spicerianum).

C. Spicerianum (spl-ser-ee-an'um). Habitat Assam. Blooms October to Feb¬ruary. Flowers pale green dotted with purple; brown-purple lip; with dorsal pure white, tinged green at the base and a broad purple stripe down the center.

C. villosum (vill-o'sum). Habitat Moulmein. Blooms November to May. Very large flowers, iridescent red, green, and purple, with green dorsal. Many fine varieties. Much prized as a parent, having been used for over two thousand hybrids.

Cymbidiums require, without exception, lath-house, outdoor, or cool-house treatment, 'feet cold, head warm.'

Cymbidium ebumeum (ee-bur'nee-um). Habitat India. Blooms February and March. Flowers white dorsal petals and lip with a golden band down the center of the throat. Has been of tremendous importance as fore¬runner of some of the finest whites. Scarce and very difficult to grow.

The first hybrid, made in 1889, C. ebumeo-Lowianum, F.C.C.1—a pri¬mary hybrid of eburneum crossed with Lowianum—has in turn become a famous and successful parent. Outstanding among the progeny is C. Mexanderi (C. eburneo-Lowianum x C. insigne Sanderi). C. erythrostylum (ery-throw'style-um).

The name means 'red column.' Habitat Annam. Blooms August to January. Flowers gleaming white with pink dots sprinkled at the base of dorsal and petals; lip more of a cream-white and lined with rose.

The fact that the flowers do not open wide gives a nun-like modesty to their appearance. Chief virtue is passing on to hybrids the characteristic of early blooming. Scarce.

C. giganteum (jl-gan'tee-um). Habitat north India. Blooms September to Oc¬tober. Flowers yellowish, striped with dark red; and lip spotted with scarlet. Keeps poorly and clouds color of brighter Cymbidiums when used as one parent.

C. grandiflorum, also called Hookerianum (hooker-i-aye'num or an'um). Hab¬itat Himalayas. Blooms November. Flowers large, but frequently refuse to mature; clear green, spotted with crimson and purple. Parent with Lowianum of nearly all the green hybrids.

C. insigne (in-sig'nee), also called C. Sanderi. Habitat Annam. Blooms March to May. Flowers broad-petaled, white to pink-lavender; lip heavily spotted with darker lavender; with touches of yellow at the throat.

C. I'Ansoni (lan'son-ee or eye). Habitat Burma and Annam. Blooms May, June. Flowers similar to both Lowianum and Tracyanum, but obviously not a hybrid but a distinct species. Crossed with C. insigne produces the lovely pink, sometimes almost red, Ceres. Scarce.

C. Lowianum (low'ee-an-um). Habitat India. Blooms February and March. Has eighteen to twenty flowers on a stem; dorsal and petals yellowish-green with dark lines; cream lip flushed with yellow and maroon; blotch in throat. Compares favorably with its hybrids in beauty and ease of culture, its flowers having fine keeping qualities. The hybrid C. Pauwelsii (C. insigne Sanderi x Lowianum) ranks with Mexanderi as a parent of many fine seedlings.

C. Parishii. Habitat Moulmein. Blooms July and August. Flowers fragrant; dorsal and petals ivory; lip ivory, largely spotted dark purple; touches of gold in the throat. Fine variety Sanderae has more flowers and better shape. Received F.C.C.

C. Schroederi. Habitat Annam. Blooms March and April. Not outstanding; similar but inferior to Lowianum and giganteum.

C. Tracyanum. Habitat Burma and Siam. Blooms October to November. Flowers large, fragrant, yellowish-green, spotted with crimson; front of petal cream, spotted crimson. Has unfortunate habit of dulling the color when crossed with Cymbidiums of more brilliant hue. Progeny C. Doris

The Royal Horticulture Society, England, presents deserving orchids with A.M. (Award of Merit) and F.C.C. (First Class Certificate).

(C. Tracyanum x insigne) seems to have overcome this failing to a certain extent and is valued as an early bloomer. While Vandas will grow with Cattleyas, they respond amazingly to warmer conditions.

Vanda bicolor, also called V. lamellate var. Boxalli (la-mel-lay'ta box'all-ee or eye). Habitat north India. Blooms March to May. Flowers brownish with darker, checkered markings; lilac at the throat.
V. coerulea (see-rule'ee-a). Habitat Assam, north India, Burma. Blooms October to December; infrequently earlier; sometimes twice in three years. The famous 'heavenly blue' orchid. Sepals equal and spread; very small lip; the whole pale blue, overcast with a network of darker blue veins. The heavier the veining the darker blue the flower appears. The texture is exquisitely fragile and glistening; the quality deceptively lasting.

V. concolor (con'color). Habitat China. Blooms January to April. Flowers about 2 inches across, yellowish-brown, white outside; lip white with rosy spots. Very fragrant.

V. Sanderiana (san'der-i-an'a), called 'Euantha' (you-an'tha) by Schlechter and 'Esmeralda' (es'mer-al'da) by Williams. Habitat Mindanao, the Philip¬pines. Blooms sometimes late summer, but usually October and November. Flowers spreading and flat as in coerulea and with the same crystal line texture, but usually much larger and slightly pansy-shaped.

In beauty unsurpassed, flowers continue to grow after breaking from the bud, lavender in shade, blushing till by maturity they are a soft rose, shading toward the base of the very large petals into a muted olive-green; lip vividly crested, yellow reminiscent of green. Flowers not infrequently 5 inches across and 6 inches deep. Long-lasting, but unfortunately difficult for amateurs to grow. V. Sanderiana hybrids prove of much stronger growth.

V. suavis (swa'vis). Habitat Java. Blooms different times. Flowers with sepals and petals oddly twisted away from the lip; white, spotted red-purple and flushed; lip rose to purple. Fragrant.

V. tricolor (Sanders says this species is probably a variety of suavis, while Schlechter lists suavis as a variety of tricolor—a further example of how even experts differ on information about orchids). Habitat Java. Blooms various times. Similar in habit and appearance to suavis; flowers more yellowish with bright dark-purple blotch at the throat.

Phalaenopsis, like Vandas, seem to appreciate slightly warmer conditions than Cattleyas.

Phalaenopsis amabilis (a-ma'bill-is). Habitat Malaya. Blooms throughout the year. Flowers large, white; red at throat. Frequently used as a parent. Many fine varieties, among which are:

P. amabilis Rimestadiana (rime'stad-ee-an-a). Habitat Java. Blooms all the year. More vigorous than the type and crosses with it to form the fine hybrid P. Gilles Gratiot.

P. grandiflora (gran-di-flo'ra), according to Schlechter the same as amabilis, to Sanders a variety of amabilis, and to Williams a separate species; important in any classification. Habitat Java and Borneo. Blooms October to January. Flowers larger than the type; yellow, not rose, at throat. P. amabilis var. aurea (or'ee-a). Habitat Malaya. Blooms different times. Flowers larger than the type, having a deep golden flush at the throat and over the curling tendrils of the lip.

In sunny location loses leaves and requires long rest; in shade grows continuously and retains leaves, blooming even during the hot dry season. Flowers greenish-yellow, barred brown; lip claw-shaped and incurved, whitish in color.

P. Lueddemanniana (loo'dee-man-ee-an-a). Habitat the Philippines. Blooms according to the location, usually May to June. Flowers white, barred amethyst and cinnamon-brown; lip pale, with deep violet at the base. Dwarf plant.
