 thc Leona and Nueces, Texas ; May. (1237.) — On rocky hills of tlie San Pedro, 

 Westcrn Texas, were gathered a few spccimcns, apparently of this species, with 

 large aiid remarkably thickeiicd achenia. 



CosMos BiriNNATUs, var. rAEviFLORUs. C. parviflorus, IL B. K. ; DC. Prodr. 5. 

 p. 606. Margin of strcams, from Barbocomori towards Santa Cruz, Sonora ; Sept. : 

 and on mountains ncar the copper mines, New Mexico; Oct. (1238.) — This 

 is the same as Fendlef s No. 447, 448 ; hut with still smaller ligules (only 3 or 4 t 

 lines long, pale rose-color). The scales of the outer involucre are lanceolate, hut 

 not narrower than in depauperate specimens of the cultivated C. bipinnatus ; they 

 are as long as the inner involucre. Although the exterior achenia are short-beaked, 

 the inner are long-beaked ; the heaks scabrous. The awns of the pappus are 2, 3, 

 or occasionally 4.

 dro and Pecos, Western Texas; May. (1231 bis.) 



BiDENs FOENicuLiFOLiA, DC. Prodv. 5. p. 603'? var. acheniis minoribus (2^ lin. 

 longis) scabro-hirsutulis. — Valleys of Sonora, between the San Pedro and Sonoita, 

 along streams ; Sept. (1232 bis.) Also gathered by Dr. Gregg, at San Antonio 

 de las Alanzaiies. — The achenia are linear-oblonor, tetragonal, but much obcom- 



pressed, and shorter than those of B. foeniculifolia, as characterizcd by De Candolle ; 

 the heads probably smaller. Perhaps it is an undescribed species. 



B. heterophylla, Ort.? DC. Prodr. 5. p. 597? var. caule ramoso ; segmentis 

 foliorum (superiorum) fere intcgerrimis. — Bed of small streams, in mountain val- 

 leys, between the San Pedro and Santa Cruz, Sonora ; Sept. (1233 bis.) — I am 

 not able to consult Ortega's figure. Our specimens consist of the upper part of 

 branched stcms, apparently of a rathcr tall herb, in flower. The lower cauline 

 leaves present are pinnately 5 - 7-parted, the upper mostly 3-parted, only a fevv of 

 the uppermost entire : the segments linear, or very narrowly linear-Ianceolate, one or 

 two lines wide, the lateral ones 1-2 inches, the terminal 2 - 3^ inches, in length. 



sparingly dcnticulatc-serrate, or nearly entire. Ligules oblong, 6 or 8 lines in 

 length, yellow.
