46 CYPRIPEDIUM. 



well known as one of the most munificent patrons of horticulture of 

 our time. 



0. Sanderianum. 



Leaves broadly ligulate, obtuse, a foot or more long, equitant at base, 

 with a sunk mid-nerve above, keeled beneath. Scapes longer than the 

 leaves, deep purple, pubescent, 3 — 5 (or more) flowered. Bracts sub- 

 triangular, acute, hairy, brown-purple, as long as or longer than the pale 

 yellow, sub-triquetral ovary, which is also studded with purple 'hairs. 

 FloAvers 4 inches across from the apex of the upper sepal to the toe of 

 the slipper ; upper sepal broadly lanceolate, acute, concave, ciliolate, 

 pale yellow -green with broad longitudinal brown stripes, hairy and 

 keeled behind ; lower sepal similar but somewhat smaller ; petals narrow, 

 ribbon-like, pendulous, 18 — 25 or more inches long, ciliate and broader 

 at the base, pale yellow bordered with brown-purple to 2 — 3 inches of 

 their length, then spotted with brown-purple to another 2 — 3 inches, 

 the remainder dull purple with here and there a pale yellow bar or 

 spot ; lip calceiform, brownish purple above, pale yellow beneath, the 

 infolded lobes narrow, pale buff-yellow. Staminode nearly oblong, pale 

 yellow and purple, very hairy at the sides. 



Cypripedium Sanderianum, Rchb. in Gard. Ckron. XXV. (1886), p. 554. Sander's 

 Reichcnbachia I. t. 3. 



A remarkable species of especial interest both to science and to 

 horticulture ; to the former because it brings the sub-section of the 

 genus to which it belongs* morphologically nearer to the South 

 American Selenipedia than any other Asiatic species known; to the 

 latter on account of its being one of the handsomest of Cypripedes, 

 and supplying the hybridist with a most distinct agency for the 

 production of new and interesting forms. It was discovered by 

 Forstermann in 1885 or 1886, while collecting orchids in the Malayan 

 Archipelago for Messrs. Sander and Co. (the introducers, to whom 

 only and its discoverer the precise habitat of the species is probably 

 at present known). 



O. Spicerianum. 



Leaves linear-oblong, 6 — 9 or more inches long, more or less undulated 

 at the margins,- dark green above, spotted with purple on the under 

 side towards the base. Scapes somewhat slender, erect, 9 — 12 inches 

 high, one- (rarely two-) flowered. Bract linear-oblong, acute, whitish spotted 

 with cinnamon-purple, sheathing the ovary to about half of its length. 

 Flowers 3 inches across vertically j upper sepal broadly obcordate, folded 

 at the middle, with the lateral margins much reflexed at the base, and
