LiTiiosPERMUM (Riiytispermum) glabrum. Ilumile, e radice 

 annua ramosum, lajve, prteter pube parca adpressa minuta glaberri- 

 raum ; foliis spathulato-linearlbus ; bracteis inflorescentiaj spiciformis 

 clcnsiflorne demiim elongataj nuUis ; floribus fere sessilibus ; calycis 

 segmentis subspathulato-linearibus foliaceis corolloe albai a^quilongis, 

 fructiferis costa inferne valde incrassata indurata; nuculis oblongo- 

 ovatis subtriquetris fere la^vibus opacis, areola basilar! baud magna. — 

 Apacbe Pass, S. Arizona, Leinmon, 1881. A singular species of Old- 

 World type, somewhat like L. incrassatum of Gussone ; the base of 

 the calyx and its exceedingly short pedicel similarly thickened and 

 indurated after flowering ; but the flowers are not accompanied by 

 bracts, the nutlets are narrower, slightly contracted at base and with 

 less dilated areola of insertion, and quite inclosed in the mdurated 

 base of the calyx. 



Jacquemoxtia Prixglei. J. ahutiloidei affinis, fticie Abutili, 

 erecto-difi'usa e basi frutescente, baud volubilis ; foliis cordatis breviter 

 acuteque acuminatis integerrimis utrinque cum ramis canescenti- 



and from C. Gay's collection, although destitute of good fruit, plainly differ 

 from the North American species. The calyx is 5-parted all but to the base 

 into linear lobes. There is no evidence that it connives over the fruit, and 

 it seems that it cannot be circumscissile.

 Beeehey, Suppl. p. 369 (that of Hook. Fl. Bor.-Am. is probably E. tendlum, 

 Gray), E.fulvum, A. DC. as to Calif, plant ; Gray, Proc. Am. Acad. x. 57, &c. 

 Erect from a rosulate tuft of thinnish radical leaves ; the slender compara- 

 tively simple stems reaching a foot or two in height : spikes ebracteate except 

 sometimes at base : calyx 5-cleft barely to the middle into oblong-lanceolate 

 and hardly at all accrescent lobes, closely connivent over the fruit, promptly 

 circumscissile above the base. The pubescence of the calyx, although gener- 

 ally rufous, is often whitish. 



E. CANESCEXS, Gray, 1. c. Diffusely spreading or depressed, or sometimes 

 ascending, more canescently hirsute, but the tips of tlie cal^-x at first not 

 rarely rufous : leaves of firmer texture : spikes bracteate below and sometimes 

 tiiroughout : calyx 5-parted (fully two thirds to the base) ; the lobes broadly 

 triangular-lanceolate or broader, accrescent, open in fruit, tardily when at all 

 circumscissile close to the base. 



Var. Anizoxicujt, Greener, more hirsute or hispid, with somewhat the 

 aspect but not the fruit of E. Toirei/i : corolla smaller, sometimes witli a tinge 

 of rose-color : calyx less accrescent : rugas of the nutlets rather sliarper and 

 towards the sides rising sometimes into elevated points or tubercles. — Arizona, 

 Greene, Prinrjle S. Utah, Marcus Jones. An intermediate form, collected on the 

 Mesas near San Bernardino by the Brothers Parish, has soft-hirsute pubes- 

 cence, softer leaves, the upper ones forming conspicuous bracts to the loose 

 spikes, and very accrescent mostly wide-open calyx.
