4. P0LYPR:&MUM, L. (Name altered from TtoXvjtQEnvog, with many 

 trunks, from the diffuse branching next the ground.) — Single species, an insig- 

 nificant weed : fl. late summer. 



P. procumbens, L. A span or more high, much branched from an annual (sometimes 

 almost ligneous) root, glabrous; the rigid stems erect or ascending rather than procum- 

 bent, 4-angled, repeatedly branching : leaves narrowly linear or almost acerose, half inch 

 or more long, the uppermost gradually reduced to bracts, their margins obscurely scabrous, 

 their bases united by a membranous stipular line : flowers sessile m the forks or somewhat 

 cymose at the summit of the branches : inconspicuous corolla barely a line long white —

5. BUDDL:&IA, Houston. {Adam Buddie, an early English botanist, who 

 corresponded with Ray.) — Shrubs, or some arborescent, a few herbaceous (mainly 

 tropical), usually canescent or tomentose with floccose or furfuraceous stellate 

 down ; the leaves sometimes dentate, the petioles connected by a transverse 

 stipular line, or by more evident stipules. Flowers commonly small, and crowded 

 into capitate clusters or cymules, which are variously disposed ; rarely some are 

 ."i-merous ; the corolla in our few (chiefly Mexican) species very short. 



* Flowers in comparatively loose and very numerous clusters, disposed in an ample and naked 

 terminal panicle. ^ ^ 



B. Humboldtiana, RcBm. & Schult. Minutely ferrugineous-tomentose : leaves 

 oblong- or ovate-lanceolate, acuminate, denticulate, 3 inches long, rounded at base, rather 

 long-petioled, copiously pinnately-veined, in age glabrate above : flowers a line and a half 

 long. — Benth. in DC. Prodr. x. 4-38. B. acuminata, HBK. Nov. Gen. & Spec. ii. 349, t. 187,

 B. lanceolAta, Benth., with smaller and narrower leaves tapering to base, and simpler 



contracted inflorescence, also inhabits Northern Mexico, and may reach the boundary. B. 



CROTONOiDEs, Gray, Proc. Am. Acad. y. 165, is from Lower California, under the tropic. 

 * # Flowers in numerous and small dense pedunculate heads, disposed in a virgate raceme. 



B. racemosa, Torr. Stems 1 to 3 feet high, loosely branching, nearly glabrous : leaves 

 from ovate-oblong to oblong-lanceolate with a truncate or obscurely hastate base, irregu- 

 larly crenate-dentate, mostly obtuse, thinnish, 2 to 4 inches long, short-petioled, green and 

 glabrous above, puberulent-canescent beneath : raceme of heads a span to a foot long : 

 heads about a quarter inch in diameter, on shorter or longer peduncles: corolla little 

 exceeding the tomentulose calyx. — Bot. Mex. Bound. 121. — Rocky banks, W. Texas.

Var. incana, Torr. 1. c. Leaves barely an inch long, fulvous-canescent-tomentose 

 beneath. — San Pedro River, W. Texas, Wright. 



* * * Flowers in solitary or geminate heads or capitate clusters : leaves, branches, and heads 

 densely soft-tomentose throughout. 



B. marrubiif olia, Benth. 1. c. Much branched, canescent or ferrugineous : leaves obo- 



vate or oval with cuneate base, arcuate, about half inch long, short-petioled, the dense 



■ tomentum somewhat velvety : flowers in a globose terminal head (half inch in diameter) 



on a short peduncle, "odorous: corolla golden yellow turning orange red." — Torr. Bot. 



Mex. Bound. 121. — S. Texas on the Rio Grande. (Mex.) 



B. SCOrdioides, HBK. Much branched, ferrugineous-tomentose : leaves narrowly 

 oblong or cuneate-linear, nearly sessile, obtuse, coarsely crenate, rugose, an inch or less 

 long : dense clusters of flowers sessile in the axils of all the upper leaves, the pair com- 

 bined around the stem into a globular head. — Nov. Gen. & Spec. I.e. t. 183; Torr. 1. c. —
