 128. Var. angustifolia, Torr. & Gray, 1. c, is a depauperate state of the narrower-leaved 

 form. — Moist ground, N. Carolina to Florida and Louisiana. 



4. POLYPRfiMUM, L. (Name altered from nalmgepvog, with many 

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

 nificant weed : fl. late summer. 



P. prooumbens, 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 in the forks or somewhat 



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

 (adventive), Maryland to Texas. (Mex., W. Ind.) 



5. BUDDLEIA, Houston. (Adam Saddle, 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 

 S-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, Roem. & 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. 438. B. acuminata, HBK. Nov. Gen. & Spec. ii. 349, t. 187, 

 not Poir. — Mexican borders of S. "W. Texas and New Mexico, Thurber, &c. (Mex.) 

 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. 



ckoton-oides, Gray, Proc. Am. Acad. v. 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. 

 Lindheimer, Riddell, Wright, &c. 



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

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



# # # Flowers in solitarj' or geminate heads or capitate clusters : leaves, branches, and heads 

 densely soft-tomentose throughout. 



B. marrubiifolia, 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. SOOrdioides, 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. 1. c. t. 183; Torr. 1. c. — 

 S. E. Texas to Arizona. (Mex.)
