APOCYNUM VENETUM, Linn.; Boiss. Fl. Or. iv. p.48. (Plate XXXVII) 
Badghis: 115, March 5, 1885. Native names: Dumb-i-roba, Kundar, Dumb-i-gosalla. 
Common in beds of streams and in marshy localities at Gulran, at an altitude of 9000 
feet. Stems about four feet high, springing from a creeping root-stock, and terminating 
in a panicle of flowers. The annual stems remain attached to the root-stocks, but by the | 
action of the wind they are soon reduced to their fibrous element, and this is found in 
bunches, having the appearance of artificial preparation. My attention was attracted 
to them by the seed-vessels still persistent on the battered branches. The fibre is a most 
excellent one, and the wonder is, as the plant seems to be common from Eastern Europe 
to China, that it has not heretofore been employed in manufactures. The bark of the 
creeping root-stocks is employed in tanning the leather skins used as water-bottles. 
Roots of this plant were sent to Saharunpore, whence we received flowering specimens 
for the Herbarium at Kew.
