ACANTHACE.E. 457 



8. ANISACANTHTJS, Nees. Species rearranged, as follows : — 



* Calyx-lobes attenuate, longer than the stipe and mostly about equalling the body of the capsule 

 (a third to half an inch long) : corolla dull red, funnelform above, with lobes much shorter than 

 the tubular portion : flowers distinctly pedicellate, chiefly in axillary and mostly leafy fascicles. 



A. Thtirberi, Grat, p. 328. From mountains of W, Texas (Havard) to those of S. W. 

 Arizona, Pringle, Parish, &c. Here belong the U. S. portion of Drejera puberula, Torr., 

 and A. pumilus, p. 328, not Nees. 



* * Calyx shorter, not surpassing and only in A. virgularis ever equalling the stipe of the 

 capsule : flowers usually, at least the upper ones, spicately or racemosely disposed along the 

 branchlets aud secund, the upper subtending leaves reduced to subulate bracts. 



A. insignis. Puberulent or nearly glabrous : leaves mostly linear-lanceolate to linear : 

 flowers pedicellate, in lateral clusters from axils of fallen leaves and short-racemose on 

 evolute small-bracted branchlets : calyx puberulent-glandular ; the almost distinct sepals 

 linear-subulate, 2 or 3 lines long : corolla rose-red or even salmon-color, 2 inches long ; the 

 linear lobes shorter than the upwardly enlarged tubular portion : stipe when well developed 

 longer than the body of the capsule. — A. pumilus, Watson, Proc. Am. Acad, xviii. 133. 

 Drejera puberula, Torr. Bot. Mex. Bound. 123, as to pi. Gregg. — Chisos Mountains on the 

 border of W. Texas, Havard, a linear-leaved form, with stipe to capsule a third of an inch 

 long. (Adj. Mex. Between Parras and Chihuahua, Gregg. Palmer, with stipe as long as 

 capsule, and in the State of Chihuahua, Pringle, with stipe half-inch long ) 

 A- ^Trigtttii, Gray, p. 328. Calyx glabrous or nearly so, remarkably short, barely 2 lines 

 long, and the lobes rather obtuse, seldom half the length of the stipe : corolla with throat 

 very little dilated. 



A. pumilus, Nees, Hemsl. Biol. Centr.-Am. Bot. ii. 522, includes A. Greggii, p. 328, aud 

 has tomentulose-pubescent and short calyx, the scarlet-red corolla of the next, but with its 

 ligulate-linear lobes longer than the narrow tube. 



A. virgtxlAris, Nees, has a nearly glabrous calyx with slender-subulate lobes, a scarlet-red 

 corolla with lobes shorter than the slender tube, and stipe shorter or not longer than the body 

 of the capsule. To this belongs the plant of Berlandier referred to Drejera puberula, Torr. 

 Also the A. pumilus, CErst. PI. Liebm. Palmer's Mexican no. 1016 has the leaves and corolla 

 of the most narrow-leaved A. virgularis, but the calyx of A. Wrightii. A.junceus, Hemsl., the 

 Drejera juncea, Torr. 1. c, is founded on a leafless branch of a slender and junciform A. vir- 

 gularis, like one recently collected in Chihuahua by, Pringle. 



12. DIANTHERA, Gronov. At end of the genus, p. 330, add: — 



Jacobinia neglecta, Sericographis neglecta, Oersted, a native of the Mexican coast-region, 

 has been received, through P. J. Berckmans, in living specimens from Florida, where it is said 

 to be spontaneous, — probably through some mistake. It is somewhat shrubby, with oblong- 

 lanceolate or broader and acuminate leaves, flowers (inch and a half long) secund, in naked 

 triple spikes on a slender axillary peduncle : calyx and bracts short : corolla light brick-red 

 and narrowly tubular : connective of the anthers broad enough to refer the plant to Dianthera, 

 the slightly higher and larger cell (or rather the connective) apiculate. 



15. DICLlPTERA, Juss. 



D. resupinata, Juss., p. 331, covers two species. The true one is annual, with a loosely 

 branched stem : leaves from ovate to oblong-lanceolate, rather long-petioled : involucral 

 bracts cordate-rotund: seeds muricate with subulate minutely setuliferous processes. — 

 Gray, Proc. Am. Acad. xx. 308. — On the borders of S. W. Arizona and Sonora, coll. 

 Coulter (557), Thurber, &c. (Trop. Mex., &c.) 



D Torreyi Gray, 1. c. Low, many-stemmed from a stout lignescent perennial caudex : 

 "leaves lanceolate, not over inch and a half long (including the short petiole) : involucral 

 bracts cordate-orbicular, usually emarginate, all more or less pedunculate : seeds scabrous 

 with acute and naked papillae. — D. resupinata, Torr. Bot. Mex. Bound. 125, and mainly of
