three. Both dorsal and lower sepals are narrow, 6in. long, and 

 curved forward ; the petals are narrow and ribbon-like, pendent, 

 ultimately becoming as much as 2ft. or even more long; they are 

 yellow at the base, the rest being brown and purple ; pouch 2in. 

 long, reddish-brown, yellow at the base, with red spots. The 

 flowers are developed in April or May, and remain fresh for 

 about a month. Ecuador, 1847. For its cultivation this plant 

 requires either warm greenhouse or stove treatment, some growers 

 preferring the one, some the other ; it thrives under both methods. 

 It requires plenty of moisture, and the soil about the roots 

 should be kept sweet and open, the slightest sourness causing the 

 roots to rot. (W. S. O., ii., t. i.) 



Var. Lindeiii is remarkable for the form of its lip, which, 

 instead of being pouch-shaped, is long and ribbon-like, resembling 

 the petals ; it is also paler in colour. This is supposed to be 

 an abnormal or monster form of the type. Syn. Uropedium Lin- 

 deiii. (R. G., X, t. 315.) 



Var. Wallisii is another most desirable addition. The sepals 

 are pale green, striped and slightly spotted with a darker green ; 

 petals white, veined with green, passing into very narrow tails, 

 tinted with pale brown at the apex ; the lip is large, white, 

 spotted and veined with crimson ; the mouth is margined with 

 yellow. Ecuador. (Fig. 156.) 



S. kaieteurum {N. E. Br.). — A synonym of S. Liiidleyanuin. 



S. Lindleyanum {Rchb. /.). — A most robust-growing and 

 desirable plant. Flowers, sepals and petals pale green, with 

 reddish-brown nerves on the outside, pubescent, with crisped 

 margins, the upper one hooded at the apex ; petals pale green, with 

 brownish-crimson veins, 2-|-in. long, falcately linear, the margins 

 recurved and ciliated; lip light olive -green, with brownish- 

 crimson veins, and densely dotted on the side lobes ; scape 

 many-flowered, pubescent. Leaves coriaceous, bright dark green.

S. longifolium {Rchb. /.). — This free-growing and stately plant 

 lias long strap-shaped, dark green, shining foliage, forming a 

 large tuft. Scape erect, from 2ft. to 3ft. high, six- to ten-flowered, 

 the flowers opening in slow succession, so that the plant is in 

 blossom for about half the year ; dorsal sepal pointed, thin, wavy, 

 green, with faint reddish streaks ; lower sepal large, boat-shaped, 

 pale green ; petals narrow, 4in. to 6in. long, twisted, green,
