p. 331. (Probably not at all D. thlaspioides, Nees, of Central America.) — Arizona, by 

 nearly all collei-tors. 

 D. pseudoverticillaris, Gray. Intermediate between the Plati/ster/ice and the Spheno- 

 stegke, annual, a foot high, branching and flowering from the base, nearly glabrous : lower 

 leaves ovate, acuminate (over an inch long), long-petioled ; upper much smaller, ovate- 

 elliptical, short-petioled, equalling the axillary subsessile leaf-like iuvolucral bracts : these 

 at first spreading, deltoid-roundish, very obtuse or retuse, rarely mucronulate, abruptly con- 

 tracted at base, there commonly coalescent into a narrow cup : corolla not surpassing the 

 involucre : seeds muricate with minutely setuliferous processes. — Proc. Am. Acad. xx. 308. 

 — Valley of the Altar, N. W. Sonora, Mexico, not far below the boundary of Arizona, 

 Pringle. Apparently also collected, long ago, in the same district, by Thurber. 



SELAGINACEtE. 



1. LAG-OTIS, Gfprtn. (/faymg, a hare, ovg, ear,) The earlier name for 

 Gymnandra, Pall., p. 332. Only one Northern species, viz. : — 



L. glaiica, G^rtx. ; Maxim. Diag. PI. Nov. Asiat. iv. 1881, 296. Gymnandra Gmelini 

 and G. SteUeri, Cham. & Schlecht., and p. 332 : these specific names taken by Maximowicz 

 as varieties. 



VERBENACE^. 



3. VERBENA, Tourn. 



v. BoxARiENSis, L. Before V. anrjusti folia, p. 336. A peculiar species, mostly tall, puberu- 

 lent, somewhat scabrous : stem square : leaves partly clasping, lanceolate, acutely serrate, 

 entire toward the base, reticulate-veiny aud rugose : spikes dense and short, sessile and 

 crowded in dense pedunculate cymes: corolla small. — Dill. Hort. Elth. 406, t. 300. — Eoad- 

 sides near Charleston, S. Carolina. (Widely dispersed through warm countries; nat. from 

 S. Am.) 



"V. littoralis, HBK. Next to T''. angustifolia. Nearly smooth and glabrous, a foot or two 

 high, fastigiately branched above : branches terminating in single and rather slender spikes 

 of small purple or blue flowers : leaves lanceolate or the upper linear, more or less serrate, 

 rugose-veiny. — Nov. Gen. & Spec. ii. 276, t. 137. — Lower California, near the border of 

 San Diego Co., Orcutt. (Variable and wide-spread species of Me.x. and S. Am.) 



V. remota, Benth. After V. canescens, p. 336, from which exclude the syn. Procumbent 

 from a perennial or perhaps annual root : leaves mostly obovate in outline, once or twice 

 3-5-parted into sliort and narrow lobes : lower flowers sparse and in the axil of leaves (as in 

 the nearly related species), and most of the upper exceeded by the linear or subulate bracts : 

 fruit shorter ; nutlets granulose-scabrous at the commissure. — PI. Hartw. 21 ; Watson, Proc. 

 Am. Acad, xviii. 136. V. Arizonica, Gray, Proc. Am. Acad. xix. 96. — S. Arizona, Lemmon, 

 Pringle, the latter distributed as V. canescens. (Mex.) 



8. CITHAREXYLUM, L. Nutlets occasionally one-celled, the seed 

 filling the cell. 



§ LyciXstrtim. Flowers solitary or subsolitary in the centre of axillary fas- 

 cicles of leaves : these remarkably small. 



C. brachyanthum. Slender, very much branched, puberulent : branchlets quadrangular: 

 leaves from linear-spatulate to obovate, quarter to half incli long, veinless, subsessile; pri- 

 mary ones articulated (in the manner of the genus) with tlie pulvinns or very short persistent 

 petiole, which after their fall often becomes spinescent (but. barely a line long): calyx
