lower racemose branches axillary, mostly opposite ; terminal spikes 

 (bi or) triparted, re volute, bracted throughout ; flowers white with 

 a yellowish throat, few, rather remote, on long, lateral, superaxiUary 

 pedicels. 



Lower cauline leaves opposite, connate and vaginate, stem sheath- 

 ing at the base, long (two to four inches in length, one-quarter in 

 breadth) linear, sublanceolate, acute or subacute ; lowest leaves 

 more attenuated towards the base ; upper cauline leaves alternate, 

 Hnear or linear-sub-spatulate, appressed, strigulose, with white hairs ; 

 all ciliate, ciUae subappressed, three-nerved, nerves submarginal, 

 inconspicuous, lamina of the lower leaves often subglabrous or with 

 a few hairs chiefly beneath on the mid-rib. 



Bracts large ; pedicels long, (from half an inch to one inch and 

 three-quarters in length, in a much smaller specimen than the one 

 here figured) tliickening upwards at the base of the calyx ; calyx 

 half as long as the flower, and twice as long as the short corolla 

 tube, segments lanceolate, acute, densely appressed, hirsute "vvithin 

 and without, Avith taAvny piU, closed and persistent in fruit. 



Corolla rotate-salver form, lobes rounded, stamens and pistil in- 

 cluded. 



Nuts rugidose on the back below, slightly granular near the 

 margin above, the subcarmated back of the apex smoothish. 



This plant appears to be closely allied to E. Chorisianum ; but 

 the leaves are opposite and sheathing, and the pedicels lateral and 

 superaxiUary, and very long, and not very short ; nor are the seg- 

 ments of the calyx simply bearded at the apex, but throughout. 

 The three-nerved character also is omitted. 



It is also near E. Californicum, but that is described as leafy at 

 the base only of the racemes ; and the pedicels very short, or only 

 one-third the length of the calyx, or nearly sessile ; and the calyx 

 longer than the flower, besides being spreading in the fruit state. 



It approaches E. iSeouleri, but that is many flowered, and the 

 racemes without bracts, and short, pedicellate flowers, small and 

 yellow. 



Dr. Torrey, in the Mexican Boundary Report, says : " We have 

 a strong suspicion that E. Californicum, E. Chorisianum, and E. 

 Scolder i are not distinct." This may also prove to be only another 

 variety, but its form is so pecuhar, we scarcely feel authorized to 

 make so large an allowance in the present state of our observations.
