2-6-tootlied above the middle, nearly veinless, the midrib prominent : peduncles mostly- 

 shorter than the leaves : heads at length cylindraceous, 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? )

nL. 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 tlie apex: peduncles filiform (1 to 4 inches long), much 

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

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

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

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

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

 corolla bluish-white. — Gray, JIan ed. 5, .341. L. replans, HBK. 1. c? Zapania lanceolata.

7. L ANT Ana, L. (An old name of a Viburnum, transferred by Linnseus, 

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

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

 mostly rngose and somewhat glaudular-odorous pinnately veined petioled leaves 

 (not rarely in threes), and axillary pedunculate heads of rather show}' .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 prickh". 

 (Transition to Lippia.) 



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

 at the apc.x, 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 (wliite or lilac) flowers, and forming an involucre. — 

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

 flowers). S. borders of Texas {L. oclorala, var. Berlandieri , Torr. ilex. Bound, and L. pan-i- 

 fo/ia, Raf.') : a form with less obtuse leaves and white flowers. L. odorata, L. Syst., seems 

 not distinct. (Trop. Am.) 



L. canescens, HBK. Cinercous-canescent throughout with fine and soft strigo?c pu- 

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

 acuminate, with cuneate base, somewhat .Tppresseil-strrate, 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. 2.59. Lippia pallescens, Benth. Hartw.

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

 1 to 3 feet high, 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-reticulated, the primary 

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