(Plant soft to the touch. E.) Stems from six to eighteen inches high, 
mostly upright, sometimes declining, but never prostrate. Leaf-scales 
in pairs, oval, pointed, scored, very downy. Leaves alternate, distant, 
the lower on long, the upper on short leaf-stalks, the uppermost 
sessile, or nearly so. Leafits of the lower leaves oblong-wedge¬ 
shaped, of the upper spear-shaped, sessile, downy on both sides, ribs 
not strongly marked, serratures barely distinguishable with a glass. 
Heads oval, woolly, sometimes on short fruit-stalks, some terminal, 
but mostly in pairs. Calyx just shorter than the blossom, scores 
almost hid by long soft hairs; teeth nearly equal, straight, awl- 
shaped, not stiff. Blossom pale red. Standard spear-shaped. Wings 
and keel equal. Woodw. The ribs upon the calyx, and its rounded 
nearly globular shape when ripe, readily distinguish this species.

Whole plant villous. Stem upright* (six to twelve inches high, E.) cylin¬ 
drical, firm, much branched. Stipulas in pairs, spear-shaped, scored with 
red veins, and ending in an awn. Leaf-stalks very short. Leafits of the 
lower leaves elliptical, of the upper nearly strap-shaped, somewhat 
notched at the end, the mid-rib lengthened into a short point. Calyx 
reddish, longer than the blossom, scored; teeth bristle-shaped, nearly 
equal, fringed with long hairs. Woodw. ( Blossoms pale red, minute. 
Spikes sometimes long and cylindrical, (whence its trivial name. E.) 
Calyx teeth pinky; the hairs when much magnified appear rough and 
knotty. E.)
