2-0-tootliocl above the nruldlc, nearly veiiilcss, tlie midrib prominent : peduncles mostly 

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

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

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

 corolla: fruit oblong-oval. — Torr. in Marcy, Uep. 2!);j, t. 17. Zupania cuneijolia, Torr. in 

 Ann. Lye. N. Y. ii. 2^4. — 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, sharply ser- 

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

 exceeding the leaves : heads eylindraeeous in age, quarter inch thick : bracts mucronate or 

 pointless : lobes of the calyx linear-lanceolate: corolla rose-purple or nearly white, short:

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

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

 varying from obovate and lanceolate-spatulatc to ovate, narrowed at base mostly into a 

 petiole, above sliari)ly serrate, pinnately straight-veined; veins ending in the sinuses: 

 corolla bluish-white. — Gray, Man. ed. 5, oil. L. irjtUins, PIBK. 1. c? Za/xniia lanceolata.

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

 in view of some resemblance to this genus, whicli should liave retained Plumier's 

 name of Cainara). — 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. Canesccnt, much branched : leaves obovate-oval or ovate, rounded 

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

 at base, rather slender-petioled : peduncles equalling or exceeding the leaf: head hemi- 

 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. imoJncrala, var. Flnridana, Chapm. ; a form with long peduncles and white 

 flowers). S. borders of Texas {L. odorata, var. Derlandieri, Torr. Mex. Bound, and L. parvi- 

 folia, Paf.') : a form with less obtuse leaves and white flowers. L. odorata, L. Syst., seems 

 not distinct. (Troj). Am.) 



L. canescens, HBK. Cincreous-canescent throughout with fine and soft strigose pu- 

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

 acuminate, with cuneate base, somewhat appressed-serrate, lineateveined and minutely 

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

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

 volucrate : corolla small, white. — Nov. Gen. & Spec. ii. 259. Lippia pal/escens, Bentli. Ilartw.

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 oblongovAte, 

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

 scabrous above and slightly canesccnt beneath, not at all rugose-reticulated, the primary 

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