pilose; leaves fascicled, subulate, linear-trigonous, or filiform, short or long; flowers terminal, capitate or 2–3 together, or sometimes solitary; calyx hirsute, its segments narrow-linear-lanceolate, ribbed, sub-trinerved, acute, much longer than the tube; vexillum villous, carina glabrous or villous; ovary very hairy. A very variable plant, sometimes robust, tall and woody, with densely tufted, short, straight or curved leaves; sometimes slender, decumbent or diffuse, with scarcely tufted or ternate, very long, filiform, curved leaves, as in A. araneosa, from which, in all cases, the present may be known by its broader, ribbed and nerved calyx-lobes. The young leaves are pilose, the older glabrescent or glabrous; they vary extremely in length, often on the same bush. In A. dubia, E. M., all but the floral are 2–3 lines long; commonly they are 4–5 lines; and in slender specimens 6–7 lines. Flowers deep yellow or fulvescent, 5–6–8 lines long. The carina varies much in pubescence, and is often quite glabrous.
