The street railway of Guaymas ends in a semi-public park, in which 
grow two trees with willow-like leaves that would not be recognized 
as belonging to the fig family by anyone knowing only the cultivated 
figs of California. The owner says they were brought from below 
San Blas, and Dr. Palmer says that at least one of them grows also 
wild in the neighboring cafons. These two trees from which were 
collected the typical specimens of Ficus fasciculata and F. Sonore, 
are separated by a short distance; one bears numerous aerial rootlets 
and sends down to the earth roots from its branches; the other has 
neither of these peculiarities, but, as /. Pal/meri, of Lower Califor- 
nia, sometimes produces an abundance of aerial rootlets, and more 
often has none, their presence or absence cannot be considered a 
specific character. The two trees of Guaymas bear a general re- 
semblance to one another; the leaves are alike, and at the time I 
thought they were one species, and afterwards was surprised to learn 
from Dr. Palmer that they represented types of two distinct species. 
Dr. Gustav Eisen, a well-known expert in fig culture; who has seen 
these same two trees, thinks it possible that they may represent the 
_ male and female forms of a single species, and says: ‘‘/. fasciculata 
‘ 
possesses in the April crop of figs very few male flowers, about half 
a dozen to each fig, and these male flowers are situated in the region 
around the eye (osteolar region), and are not found dispersed among 
the female and gall flowers lower down,”’ 
Along the railway from Guaymas to Hermosillo and in the sur- 
rounding region, one of the most abundant plants is the thorny bush, ° 
or small tree, O/neya Tesota. At this time all its flowers were open, 
and they were so numerous that horses and cattle become fat eating 
them from the branches within reach, and from the ground where 
they have fallen. 
The irrigated fields and gardens about Hermosillo were quite green 
when compared with the surrounding country, and much vegetation 
of interest was found, especially along the ditches and in the hedge 
rows. The dry rocks and hills of course did not produce many — 
plants at this time of the year, but some collections of Perityle made 
among them, and by Dr. Eisen at San Miguel de Horcasitas, gave 
. evidence that the awns of the pappus may be present or absent in 
the same species. Area macroptera, a perennial plant, very com- 
mon in the vicinity of Hermosillo, does not seem to suffer from the 
lack of moisture, for along the roads and in the very driest situations
