AND THEIR MANAGEMENT. 157 



Cypripediiim. 



hairy on the outside ; petals large, almost as broad as long, the 

 lower edges meeting behind the labellum ; pouch small, as in 

 C. concolor. Hitherto this species has flowered at various 

 seasons. The flowers are very varied in their marking. Burma, 

 18SS. (,Fig. 45.) 



There are several named varieties of C. I'flladiliuii, the most 

 prominent amongst these being C. b. albiiin, in which the flowers 

 are wholly ivory-white, and fine in form and substance. It is 

 one of the most beautiful of the white-flowered Orchids. 



C. Boxallii (/?i"/;/'./). — This handsome, free-flowering species is 

 related to C. villosjun, which it resembles in foliage and in the form 

 of its flowers. Leaves green, strap-shaped, ift. or more long. 

 Scapes erect, one- or two-flowered ; flowers large ; dorsal sepal 

 reflexed at the sides, greenish, with a white margin and numerous 

 large purple spots ; petals and pouch greenish-yellow, tinged with 

 purple. The whole surface of the flower has a shining, varnished 

 appearance. This species may be grown in a cool, intermediate 

 temperature. It blossoms in January and February. Burma, 1S77. 

 (I. H., ser. iii., t. 345.) 



There are several named varieties of this, but the following is the 

 only one deserving special mention : 



Var. atraium. — Flowers very large ; dorsal sepal green, with a 

 white margin and large blotches of black-brown ; petals and pouch 

 reddish-purple and pale green. (G. C, i., 1S87, fig. 47.) 



C. callosum {Rclib. /.). — In some respects this most desirable 

 species resembles C. barbatum and C. Laivre)icea)iu?n. Leaves 

 6in. to gin. long, bright green, with darker green tessellations ; 

 scape i2in. to i5in. long, one- (sometimes two-) flowered. Flowers, 

 upper sepal 2\\x\. to 3in. broad, folded at the mid-vein, and undulate 

 in the apical half, white, with alternate longer and shorter veins 

 that are green at the base, becoming deep purple upwards ; lower 

 sepal smaller, white, with pale green veins ; petals slightly defle.xed, 

 pale green, tinted with pale rose-purple towards the ape.x ; margins 

 ciliated, with some blackish warts on the upper one ; lip brown- 

 purple, shading to green beneath. Cochin China, 1886. 



Var. SandercE. — This is the albino of the species. The flowers 

 are wholly greenish-yellow and white. A choice and desirable 

 addition, which is now becoming fairly distributed in collections. 

 No collection of Cypripediums is complete without it. (Fig. 44.) 



C. Chamberlainianum {O'Brien). — Flowers rosy-purple and 

 white, in form somewhat resembling those of C. spectabile ; sepals 

 strongly pubescent at back; bracts large, boat-shaped; scapes 2ft.
