"The _leaf-blade_ is narrow, lanceolate, acuminate, glabrous but sometimes tubercle-based hairs occur just on the margin at the base of the leaf-blade close to the white band, varying in length from 1 to 6 inches and in breadth 3/16 to 5/16 inch; the margin is minutely and distantly serrate, midrib is quite distinct and there are three main veins on each side and three or four smaller between main ones."
"The branches are numerous and in some species spiny; the narrow, often short, leaf-blade is usually jointed at the base and has a short stalk, by which it is attached to the long sheath."
"[309] Although it is generally admitted that the filament of the stamen corresponds to the stalk of the leaf, and the anther to the leaf-blade, yet there are some points on which uncertainty still rests."
