51. STAUROPSIS, ReicTib.f. 



Epiphytes; stem stout, leafy. Leaves distichous, coriaceous, flat, 

 2-lobed. Floiuers in lateral racemes. Sepals and similar but smaller 

 petals widely spreading. Lip sessile, adnate to the base or sides of the 

 column, incurved, base simple or saccate, lobes narrow, disk naked or hairy. 

 Column short, thick, foot 0, top truncate ; anther 1 -celled ; pollinia 2,-sub- 

 globose, 2-cleft ; strap broad, gland large. Species about 8, Malayan. 



1. S. grigranteus, Benth. in Gen. Plant, iii. 572; flowers very large 

 golden-yellow ocellately blotched with cinnamon, sepals and petals spathu- 

 lately obovate, lip white hatchet-shaped obtuse, base cordate, side lobes 

 rounded, midlobe narrow obtuse fleshy, disk with a broad conical callus.

TENASSERIM ; at Moulmein, WallicJi, Griffith. 



Stem pendulous. Leaves 1-2 ft. by 2-3 in., very thick, flat. .Sacewe 10-15 in., 

 decurved, many-fld. ; rachis very stout ; bracts short, broad ; flowers 3 in. diam. ; 

 lateral sepals horned behind below the tip. Griffith describes two sterile stamens 

 between the lateral sepals and petals. 



2. S- undulatus, Benth. mss. ; flowers 1^ in. diam. nearly white, 

 sepals and petals spathulately oblanceolate waved, base of lip saccate 

 adnate to the sides of the column, midlobe laterally compressed 3-ridged 

 Yanda undulata, Lindl. in Journ. Linn. Soc. iii. 42 ; Reichb. f. in Gard 

 Chron. 1875, ii. 212 ; 1878, i. 168. 



EASTERN SUBTROPICAL HIMALAYA; Sikkim and Bhotan, ascending to 6000ft. 

 The KHASIA HILLS, alt. 5-6000 ft. 



Stem 6-10 in. ; sheaths and scape minutely warted. Leaves 3-4 by - in., 

 unequally obtusely 2-lobed. Scape 5-8 in. and raceme strict, erect, laxly few-fld. 

 near the top ; bracts \ in. long, broad, obtuse ; flowers white flushed with pink or 

 purplih ; sepals acuminate, undulate, lateral deflexed ; petals similar but smaller ; 

 lip yellow, base orbicular, sides streaked with pink ; midlobe linguiform ; tip 

 truncate, sometimes purplish ; pollinia globose, strap short, gland large transverse. 

 I am very doubtful as to the affinity of this plant, which differs from 8. giganteus 

 in the base of the lip being adnate to the sides of the column, and forming with it a 

 cup with a thickened rim. 



52. ARACHNANTKE, Blume. 



Characters of Stauropsis, but lip jointed on to the base of the column 

 and mobile. Species 5 or 6, Himalayan and Malayan. 



This character of the mobile lip requires confirmation in the living plant of some 

 species. 



* flowers in simple racemes. Side lobes of lip much smaller than the 

 midlobe. 



1. A. Cathcartii, Benth. in Gen. Plant, iii. 573; scape few-fld., 

 lateral sepals and petals broadly elliptic obtuse, side lobes of lip small 

 rounded. Esmeralda Cathcartii, Reichb. f. Xen. Orchid, ii. 38; Walp.
