This species appears to come nearest Habenaria diphylla 
Dalz., of the section Trimeroglossa . It is readily distinguished from 
the latter, however, by its much larger size and looser inflorescence 
and by the spur being much larger than the ovary.

Arracan Yomahs. 
Distribution,— Eastern Himalaya, Assam, Burma.

887. Curcuma Linn. 
658. Curcuma sessilis n. sp. 
Root-stock large, tubers vertical, ovoid, brown externally, white 
internally, 5-7*5 cm. long, and about 2*5 cm. thick, rootlets white 
as thick as a goose-quill. Leafy tuft few-leaved, less than 60 cm, 
high, basal leaf-sheaths purple, petiole and sheath together about 
15.17*5 cm. long, lamina green, narrowly lanceolate, 17*5-20 cm. 
long, 2*8-3*8 cm. broad, pubescent on both surfaces. Spike sestival, 
appearing in June, developed just before the leaves, subsessile, 
about 1 r8 cm. long, lower bracts green, those of the coma purple. 
Flowers smaller than the bracts, calyx very short, obscurely toothed, 
corolla tube about 2*5 cm. long, white, segments sub-equal, ovate, 
acute, with margins incurved towards the apex, posterior segment 
tipped with red. Lateral staminodes oblong, apex incurved, faintly

Minbu district, Shaik Mokim ! 
The writer would incline to place this species near Curcuma cassia 
or C. ssruginosa y from either of which it is distinguished by its much 
smaller size and practically sessile spike. 
659. Curcuma plicata Wall. 
Nwamadaung hills. 
Distribution. — Burma. 
This plant in the living state is very like the drawings of Curcuma 
plicata in the Calcutta Herbarium, but differs from Wallich’s speci- 
mens in having glabrous instead of pubescent bracts. 
660. Curcuma parvula n. sp. 
Rootstock small, ovoid, with a few thick white downward directed 
branches ending in small oval tubers about 2 cm. long and 1*2 cm. 
thick. Plant dwarf, not much over 20 cm. high. Leaves 5-8 in a
