different, since it is a native of the west. Yet the only New Mex- 
ico record is one of Fendler, 1847! Prof. E. O. Wooton has found it 
at Riley’s Ranch, on the west side of the Organ Mts., N. M., and I 
have observed it at Santa Fé; thus in New Mexico we get a vertical 
range of 2,000%, viz., from 5,000 to 7,000. In Arizona Prof. Wooton 
found it at the Hardy water tank, eight miles east of Winslow; and 
this is actually the first specific locality in that territory, according to 
Mr. Pammel’s account. This is also apparently the most western lo- 
cality on record, as it is not reported from California, and was not 
found by the Death valley expedition. The first time I ever found 
S. rostratum was at Oxford, Furnas co., Nebraska, in July, 1887. In 
Colorado, while it is common on the plains at the eastern foot of the 
mountains, at least from Denver to La Junta (where I found it this 
year), it does not ascend into the mid-alpine zone. There is another 
Solanum which shares with S. rostratum the credit (or discredit) of be- 
ing the original food of the Colorado potato-beetle, namely, S. e/eag- 
nifolium. This is in New Mexico a species of the upper and middle 
Sonoran zones, going up the Rio Grande valley, to my knowledge, 
from El Paso to Bernalillo, in great abundance. It does not occur in 
the Transition, at Santa Fé, except that this year I found there a 
single patch of it, growing vigorously. The characteristic species of 
Solanum at Santa Fé are S. Jamesti and S. triflorum, the former espe- 
cially abundant. \S. Jamesii I have never observed in Colorado, but 
S. triflorum is the common species of the mid-alpine zone, in Wet 
mountain valley. 
At Santa Fé one finds many European weeds. It is probable that 
their presence is mainly due to the zeal with which the late Arch- 
bishop Lamy imported plants from France, the weeds coming acci- 
dentally with them. I found Senecio vulgaris quite abundant, also 
Sonchus oleraceus and Plantago major. Erodium cicutarium was found, 
and plenty of a dock which appears to be nothing but Rumex obtust- 
folius. There is also a large purple flowered Tragopogon in quantity; 
it can only be 7. porrifolius, I assume. F inally, I was quite pleased 
to come across a good patch of Convolvulus arvensis —T. D. A. COCK-
