ACANTHACEiE. 457 



8. ANIS ACANTHUS, Nees. Species rearranged, as follows: — 



j|t Calyx-lobes attenuate, longer than the stipe and mostly about equalling tlie body of the capsule 

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

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



A. Thlirberi, Gkay, p. 328. From niouutaius of W. Texas (Havard) to those of S. W. 

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

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



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



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



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



A. insignis. Pubemleut or nearly glabrous : leaves naostly linear-lanceolate to linear : 



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



evolute small-bracted branclilets : 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 tiie 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, Ilavard, 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, Prmgle, with stipe half-inch long ) 



A. W^riglltii, Gkay, 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. PU.MiLUS, Xees, Hemsl. Biol. Centr.-Am. Bot. ii. 522, includes A. Greggii, p. 328, and 

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

 ligulate-linear lobes longer than the narrow tube. 



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

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

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

 Also the A. pumilus, Qj^rst. 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. junccus, Plemsl., 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 Chihualiua by, Pringle. 



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



jACOBfNiA NEGLECTA, Sericograpliis 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 s|)ikcs on a slender axillary peduncle : calyx and bracts short : corolla light brick-red 

 aud narrowly tubular : connective of the anthers broad enough to refer the plant to Dianlhera, 

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



15. DICLlPTERA, Ju.ss. 



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

 branched stem : leaves from ovate to oblong-lanceolate, rather long-jjctioled : 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 (5.57), Thurher, &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-orlticular, usually emarginate, all more or less pedunculate : seeds scabrous 

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