[Vol.. III. 



usually less than \' long; stipules small, lanceolate; flowers few, on slender i-flowered axil- 

 lary peduncles, the first usually from the axil of the first stem-leaf , yellow, 3 // -5 // broad; petals 

 broadly obovate, slightly exceeding the narrowly lanceolate, sub-equal sepals and bractlets; 

 stamens about 20; style terminal, filiform. 



In poor soil, New England to Pennsylvania. Closely related to P. Canadensis, but differing in 

 its smaller size, denser and perfectly appressed pubescence, earlier blooming, and the lack of the 

 long adsurgent stems characteristic of that species.

Perennial by horizontal rootstocks, villous-hirsute, 

 or glabrous in age. Leaves basal, 5 / -i2 / ' high; peti- 

 oles much longer than the blades, usually less densely 

 pubescent than the scapes; leaflets cuneate-obovate or 

 broadly rhomboidal, i)4 / ~3 / long, coarsely and irregu- 

 larly crenate or lobed; scapes erect, solitary or sev- 

 eral together, commonly shorter than the leaves, cor- 

 ymbose at top; calyx usually hairy, the tube broadly 

 turbinate, iX // - T ^ // long, the segments triangular- 

 lanceolate, or lanceolate-acuminate, often shorter than 

 the tube; petals linear-oblong or narrowly elliptic* 

 shorter than the calyx-segments or barely longer; 

 achenes obovoid, i}^ // long. 



In woods and shaded soil, southwestern Virginia to 

 North Carolina, Tennessee and Georgia. Ascends to 2100

Trees or shrubs often with spines in the axils, with 2-pinnate leaves, the pinnules few or nu- 

 merous, and small spicate or capitate perfect flowers. Calyx campanulate, with 5 short teeth. 

 Petals 5, valvate, distinct, or connate below. Stamens 10, distinct; filaments long. Ovary 

 often stalked, many-ovuled; styleslender or filiform; stigma very small. Pod linear, straight 

 or curved, compressed, leathery, indehiscent, the mesocarp spongy or dry. Seeds flattened. 

 [Ancient name for some very different plant] 



About 15 species, natives of warm and tropical regions, 

 occur in the southwestern United States.

A glabrous or minutely pubescent shrub, the 

 axils usually with a pair of sharp spines. Leaves
