tis); corolla subrotata caerulescente, appendicibus brevibus obtusis- 

 sirais ; capsula in exemplo abortu moiiosperma obloiiga acutiuscula 

 (Ihieam longa) calycem baud superaiite ; semine subrugoso. — Califor- 

 nia, in Fresno Co., 1881, Parry. The species of this group are not 

 very clearly defined ; but no one has a foliaceous calyx of this fashion. 

 The expanded corolla is barely 4 lines in diameter. The fruiting 

 calyx does not exceed 2 lines in length ; and the one or two quasi- 

 petiolate lobes are a line in breadth. 



Eriodictyon angustifolidm, Nutt., var. pcbens. Foliis ssepe 

 latiuscule lanceolatis baud lucidis supra puberulis subtus tomentulosis ; 

 ramulis pube brevi et calycibus villo denso indutis. — San Bernardino 

 Co., California, 1881, aS'. B. ^- W. F. Parish, Parry. With the 

 foliage of E. glutinosum as to shape, and a pubescence which makes 

 some approach to that of E. tomenhisnm, this has the short and nearly 

 campanulate corolla of E. angustifolium, to which it is acrordingly 

 referred.* 



* Revision of the Racemose Basi-bracteate Species q/" Echinospekmum, in Correction 

 oftlie Syn. Flora of N. America, ii. p. 189. 



1. Very loosely and small-flowered biennials, or perhaps sometimes annuals : 

 corolla and nutlets not over 2 lines broad or long; leaves tliin and green. 



E. ViRGiNicuM, Lehm. Nutlets of the globose fruit equally short-glochidi- 

 ate over the whole back. 



E. piNETOEUM, E. L. Greene, in herb. Cauline leaves small, narrowly oblong, 

 mostly obtuse : racemes erect and simple ; nutlets only marginally glochidiate 

 with flattened prickles, but the flat or concave ovate dorsal disk glochidiately 

 muriculate. — New Mexico, on tlie Pinos Altos Mountains, July & Sept. 1880, 

 E. L. Greene. 



E. DEFLEXUM, Lehm. Nutlets only marginally glochidiate, with the dorsal 

 disk minutely scabrous : in var. Americanum (which makes some approach to 

 E. Virginicnm) the somewhat more granulate dorsal disk not rarely bears two 

 or three small glochidiate prickles on an obscure midnerve ! 



2. More or less larger- and less looselj'-flowered : racemes usually paniculate : 

 tube of the corolla not at all or only slightly surpassing the caly.x : glochi- 

 diate prickles either wanting on the back of the nutlets or shorter and 

 smaller than those of the margin. 



* Biennials : dorsal disk of the nutlets wliolly unarmed, granulate-scabrous. 



E. URSiNUM, E. L. Greene, in herb. Hispidulous or hispid on the stem and 

 leaves, stout : nutlets small (2 lines long), with broadly ovate dorsal disk plane 

 or nearly so, the subulate flattened marginal prickles short. — New Mexico, on 

 gravel beds of Bear Caiion in the Bear Mountains, New Mexico, 1880, E. L. 

 Greene. To tliis, in flower only, evidently belongs no. G33, Fendler, N. Mexican 

 Coll., which had been referred to the next species. 



E. FLORiBUNDUM, Lehm. Pubescent, rather strict : nutlets larger, with
