98 . ORCHIDS ОҒ THE SIKKIM-HIMALAYA. 
The sepals and petals are green, minutely spotted with brown; the lip is white 
with a yellow spot at its base and reddish spots on the edges of the side and apical 
lobes; the column is yellow with a white blotch. 
PLATE 135 —(Chrysoglossum erraticum, Hook. fil. A plant; of natural size. Fig. 1 the sepals 
and petals, detached, 2 ovary and column, showing its short spur and the lip, side view, 3 lip, 4 the 
base of the lip, showing the m auricles, 5 column with the anther in situ, 6 anther, 7 pollinia; 
all enlurged. 
10. Diglyphosa, Blume. 
Terrestrial with creeping rhizome and long narrow pseudo-bulbs, each bearing a 
solitary, membranous, elliptic, plicate, petiolate leaf, Scape lateral near the base of the 
pseudo-bulb, erect; the raceme many- and densely-flowered, with a thick rachis. Sepals 
broadly lanceolate, the lateral pair and the petals faleate. Lip jointed to the foot of | 
the column, mobile, oblong, bilamellate from base to apex, with obscure basal but no 
lateral lobes; the apical lobe narrow. Column with a foot half as long as itsclf, but 
without lateral wings or auricles. Anther with two projecting triangular wings; pollinia 
2, elliptic, slightly obovate, sometimes attached to a small mass of adhesive matter. 
Distrib. two species, one Malayan and one British Indian. 
A genus closely allied to Chrysoglossum, but differing from it in the column having rather a 
long foot, but neither wings nor auricles; in the polliuia being elliptic and slightly clavate (instead 
of sub-globular or unequally 4-sided); in the petals and sepals being much broader; in the lip being 
without basal or side lobes; and in the raceme being many- and densely-flowered, and having a thick 
rachis and large persistent coloured bracts. The genus was first founded by Blume in his Bijdragen 
(p. 936 t. 60). The same author again described and figured in his Flora Jave (Orchid. 138, t. 60) 
the only species known to him (D. latifolia). Іп the text of the Flora Javæ, Blume changed the name 
of the genus to Diglyphis, retaining that of Diglyphosa in his figure. The older name must of course 
stand. 
DIGLYPHOSA MACROPHYLLA, King and Pantling. 
Pseudo-bulb sub-cylindric, broadly elliptic, thin, 6 in. long. Leaf plaited, slightly 
narrowed at base and apex, 15 in. long and 7 in. broad; its petiole 8 in. long. 
Басете about 6 in. long, many-flowered, its stalk about 12 in. long, sparsely bracteo- 
late. Flower *5 in. across; the ovaries ‘5 in. long; Pract lanceolate, reflexed, shorter 
than the stalked ovary. Sepals sub-equal, the dorsal lanceolate, the laterals falcate. 
Petals slightly broader than the sepals, falcate. Lip . contracted into a claw at the 
base, mobile, oblong, abruptly decurved from the obscure rounded basal lobes, the 
apex minutely emarginate and decurved; upper surface with two bold longitudinal 
minutely hispid lamellae running from the base to nearly the apex where they unite. 
Mentum none. Anther with two projecting triangular wings. Pollinia 2, attached to а 
small viseus. Chrysoglossum macrophyllum, King and Pantling, in Journ. As. Soc.

The colour of the Ries is golden-browa throughout, that of the scape and rachis 
is purple. The flowers have an unpleasant smell. The only other species of the
