 BENGAL (wild in Sot. Gard. Calc.'). BUEMA, Wallich. The DECCAN PENINSULA, 

 common on the Western Ghats. 



Leaves f-5 in. Scape 4-10 in. ; sheaths many, erect, lanceolate, broad or narrow. 

 Splice 2-6 in., cylindric; bracts ciliolate; flowers in. diam., yellow-green ; lateral 

 sepals 3-5-nerved, deflexed ; petals as long, 2 -nerved; spur clavate or fusiform 

 below the middle; anther-cells distant, tubes short spreading funnel-shaped; 

 caudicles of pollinia short, glands large; stigmatic processes long, adnate to the lip; 

 rostellum triangular, acute. Capsule % in., fusiform, turgid, curved, obscurely 

 beaked. 



59. H. flavescens, Hook.f. ; scape slender, leaves few radical linear- 

 oblong yellowish when dry margined with yellow, scape slender few-fid., 

 bracts equalling the ovary, dorsal sepal broadly ovate, lateral oblong-lan- 

 ceolate acute, petals larger than the sepals ovate-oblong, lip rather longer 

 than the sepals 3-partite side-segments slender, mid-segment linear-oblong 

 margins recurved, spur shorter than the ovary tip clavate. 



The CONCAN, Law, &c. 



A much more slender plant than H. marginata, turning yellow when dry, with 

 fewer smaller flowers, and a more distinctly beaked ovary ; but perhaps only a form 

 of that plant. 



60. H. viridiflora, Br. Prodr. 312 ; scapigerous, leaves shorter than 

 the scape linear-lanceolate not margined, raceme many-fld., bracts much 

 shorter than the beaked ovaries, dorsal sepal orbicular- ovate much shorter 

 than the broadly oblong lateral, petals broadly obliquely ovate as long as 

 the dorsal sepal, lip longer than the sepals 3-partite, segments slender, 

 spur as long as the beaked ovary thickened below. Lindl. Gen. & Sp.
