Hoarea undulaeflora. Swt. horl. brit. p. — . n. 35. inedit. 
Root tuberous, divided into several crowns at the top. 
Leaves very variable, spreading in a radiate form, hairy : 
lower ones simple, roundly oval, very obtuse : upper ones 
ternate or trifid, the middle leaflet of the size and shape of 
the lower leaves, side ones much smaller, oblong, obtuse : 
the leaves at the base of the scape, pinnatifid. Petioles 
long and flexible, slightly flattened on the upper side and 
rounded on the lower, winged nearly half way up by the 
stipules, thickly clothed with unequal hairs, as are the 
scape and peduncles. Stipules attached to the petioles, 
the points subulate. Scape proceeding from the crown of 
the root, generally producing a small leaf and 3 or 4 
bractes at the base of the peduncles. Umbels many- 
flowered. Involucre of several subulately linear villous 
bractes. Calyx 5-cleft, villous, and bearded with a little 
tuft of white hairs, segments linearly lanceolate with mem- 
branaceous margins, upper one erect, the others reflexed. 
Nectariferous tube slightly flattened, thickly covered with 
unequal hairs tipped with a white pellucid gland. Petals 5,

a dark brown, or nearly black, with white ungues. Fila-
