to 10 ciTi. long or more and 1 cm. wide, ribbon-like. crisp, fleshy, with 
broad blunt apices ; when gathered dry and in ripe fruit, small with 
cup-like base and fimbriate fruit-bearing outer ends. Secondary 
shoots on upper edges of margins, usually 2-3 mm. apart and hence 
rather crowded in flower, rarely on central parts of thallus, all or some 
ultimately floriferous, and then closely sessile on thallus and as broad 
as long before emergence of spathe. Bracts 2-7, usually 4, markedly 
cowl- or helmet-shaped, keeled, usually divaricate when open. 
Vascular bundles leading to flowers, with immediately adjacent tissue 
becoming woody, the rest of the thallus tissue deciduous, thus much 
altering the habit of the fruiting specimens. Spathe oblanceolate to 
6 mm. long, splitting irregularly at the tip or occasionally on the under 
side. Pedicel of flower about 4-5 mm., elongating in fruit to 8-25 mm. 
Stamens equalling ovary and stigmas. Stigmas subulate, unequal, the 
lower larger. Capsule 8-ribbed, or with 2-4 extra ribs intercalated ; 
ribs very narrow. 
Assam and Burma on rocks in streams to 4,500 feet. 
Flowers October to February. 
This species probably may be divided into two or more 
varieties or species. Wallich’s original plant, found by 
Gromez in the Sylhet Hills, and all the Cherrapunji speci- 
mens of D. Wallichii apd D. pterophylla, so far as I am 
aware, have short pedicels and eight ribs to the capsule. Some 
of Griffith’s Assam specimens, locality unknown, have longer 
pedicels and more ribs than eight, and come near the speci-^ 
mens collected by Lehmann at Chepedong near Moulmein in 
Burma, and those collected in the same district by Parish 
in 1859. As mentioned above, D. pterophylla cannot be 
regarded as a separate species, being founded on material 
differing only from the typical D. Wallichii in having the 
keel of the bracts less disintegrated. I incline to think that 
there are two good varieties, geographically separated by the 
great valley of the Surma.
