Lanlana. VERBENACE^E. 339 



2-6-toothed above the middlo, nearly veinless, tlie midrib prominent : peduncles mostly- 

 shorter than the leaves: heads at length cylindraceous, almost half inch thick: bracts 

 rigid, broadly cuneate, abruptly acuminate from tlie truncate or retuse dilated summit : 

 calyx deeply 2-cleft ; the lobes oblong and cmarginate, shorter than the tube of the (white.' ) 

 corolla : fruit oblong-oval. — Torr. in Marcy, Rep. 293, t. 17. Ziipania cuneijhlia, Torr. in 

 Ann. Lye. N. Y. ii. 234. — Plains, Nebraska to New Mexico and Arizona. 



L. nodiflora, Michx. Creeping extensively, some branches ascending, " annual " or 

 probably perennial, cinereous or greenish : leaves cuneate-spatulate or oblanceolate, sessile 

 or nearly so, obscurely veiny or almost veinless, the long tapering base entire, sliarply ser- 

 rate from above the middle to the apex: peduncles filiform (1 to 4 inches long), much 

 exceeding tlie leaves : heads cylindraceous in age, quarter inch thick : bracts mucronate or 

 pointless : lobes of the caly.x linear-lanceolate : corolla rose-purple or nearly wiiite, short : 

 fruit globose or didymous. — Fl. ii. 15. Zapania nodiflora, Lum. 111. t. 17. Verbena uodijiora, 

 L. ; Sibth. Fl. Grajc. t. 5-53. — Low grounds, Georgia to Texas and southward : also Cali- 

 fornia. (Cosmopolite in torrid zone.) 



L. lanceolata, Michx. 1. c. Like the preceding, and perhaps passes into it, but greener, 

 minutely and sparsely strigulose : leaves tiiinner, mostly broader (name therefore inapt), 

 varying from obovate and lanceolate-si)atulate to ovate, narrowed at base mostly into a 

 petiole, above sharply serrate, pinnately straight-veined ; veins ending in the sinuses : 

 corolla bluish-white. — Gray, Man ed. 5, 341. L. rejilans, IIBK. 1. c? Zapania lanceolata, 

 Beck in Am. Jour. Sci. xiv. 284. — River banks, E. Penn. to Illinois and Missouri, south to 

 Florida and Texas. (Mex.) 



7. LANTANA, L. (An old name of a Viburnum, transferred by Linnoeus, 

 in view of some resemblance to this genus, which should have retained Plumier's 

 name of Camara). — Shrubs or undershrubby plants of warm regions; with 

 mostly rugose and somewhat glandular-odorous pinnately veined petioled leaves 

 (not rarely in threes), and axillary pedunculate heads of rather showy small 

 flowers ; in summer. Several species common in gardens, two or three indigenous 

 to our southern borders. 



§ 1. Drupe thin-fleshed or somewhat dry, at least with nutlets contiguous and 

 usually cohering more or less into a 2-celled putamen : stems never prickly. 

 (Transition to Llppia.) 



L. involucrata, L. Canescent, much branched : leaves obovate-oval or ovate, rounded 

 at the apex, crenate, rugulose and veiny, scabrous above, soft-tomentose beneath, cuneate 

 at base, rather slcnder-petioled : peduncles equalling or exceeding the leaf : head liemi- 

 spherical or at length globose, not elongating : bracts silky, ovate, or the outermost some- 

 times oblong, these as long as the (white or lilac) flowers, and forming an involucre. — 

 S. Florida (L. inrolncrata, var. Floridana, Chapm. ; a form with long peduncles and white 

 flowers). S. borders of Texas (L. odorala, var. Berlandieri, Torr. Mex. Bound, and /.. ])arvi- 

 folia, Raf.^) : a form with less obtuse leaves and white flowers. L. odorala, L. Syst., seems 

 not distinct. (Trop. Am.) 



L. canescens, HBK. Cinereous-canescent throughout with fine and soft strigo.se pu- 

 bescence : branches slender: leaves oblong-lanceolate or ovate-lanceolate and gradually 

 acuminate, witli cuneate base, somewhat appressed-serrate, lineate-veined and minutely 

 rugose, about the length of the slender peduncles : heads ovoid, small, in age sliort-oblong: 

 bracts ovate and ovate-lanceolate, acuminate, lax ; the exterior larger, spreading and in- 

 volucrate : corolla small, white. — Nov. Gen. & Spec. ii. 250. Lippia pallescens, Benth. Ilartw. 

 245. As yet collected only on the Coahuila (Mexican) side of the Rio Grande, Berlandier, 

 Bigelow. (Trop. Am.) 



L. macropoda, Torr. Cinereous with minute strigulose pubescence : stems slender, 

 1 to 3 feet higli, herbaceous almost or quite to the base : leaves ovate or oblong-ovate, 

 acute, coarsely and sharply serrate, obtuse or somewhat cuneate at base, petioled, usually 

 scabrous above and slightly canescent beneath, not at all rugose-reticidated, the primary 

 veins consjncuous and running straight to the sinuses : peduncles twice or thrice the length
