 open at night." Common about Alamos, climbing over trees, bushes, fences, etc. 

 March 26 to April 8. No. 305. This species is only known from Palmer's (No. 75)

Solanum Fendleri Van Huck. and Miill. About 3 feet high. Only a single plant 

 found and this in poor condition. At the base of Alamos Mountain, March 25 to 

 April 8. No. 364. This approaches nearest Fendler's No. 254, from Panama, of 

 any specimen seen in Gray or National Herbarium, but the pubescence is redder, 

 stems somewhat thorny, and racemes shorter. 



Both these plants are merely tentatively referred as above as better material 

 may place them quite differently.

 less thorny : leaves pinnately parted with ovate to oblong segments irregularly 

 toothed or cleft : racemes few-flowered : pedicels of the flower very short : of the 

 fruit 6 lines long, somewhat thickened: corolla small, 4 to 6 lines in diameter, 

 white : stamens irregular, 4 short, 1 long and curved : fruit very prickly.— Only a 

 few plants found in shade near Alanms. September 16 to 30. No. 633. Here 

 should be referred S, sisyinbriifoHmn Gray, Proc. Amer. Acad. xxi. 434. Al- 

 though a larger plant than Palmer's present plant, the flowers are much 

 smaller than in S. sisymbriifolmm. 



Solanum Amazonium Ker. A loose growing shrub 2 to 3 feet high with showy 

 purple flowers. Here should be referred No. 237 (1885) of Palmer from SW. 

 Chihuahua. It is S. elwafjnifolium Gray, not Cav. Proc. Amer. Acad. xxi. 434. 

 It diflfers conspicuously from S. elaagnifoUum in its slender, curved and dissimi- 

 lar stamens, and in its erect, fruiting pedicels: In the sterile flowers the calyx 

 is naked and three of the anthers much longer (6 lines long) ; in the fertile and 

 lower flowers the calyx is armed with prickles and the anthers nearly equal, or 

 often longer. Near Alamos. March 2(5 to April 8. No. 314. 



Solanum verbascifolinm L. This is a shrub 4 to 5 feet high ; its fruit is " orange- 

 colored," Common along river banks among bushes. Alamos. March 26 to 

 April 8. No. 392.
