Macbride — Various American Spermatophytes 51 
So far as I have been able to discover no known species of Guat- 
teria has the fruits so long-stipitate as those of this species. The 
collectors’ notes indicate that the tree has a spread of 90m. The 
native name “ Solera’ probably originates from the resemblance 
of the fruits to rounded building stones. 
Duguetia vallicola, spec. nov., arbor 20-25 m. alta i ramulis 
J. Pinzon, no. 3 (type, Gray Herb.). 
This species may be compared with D. Spixiana Mart., which, 
however, has more or less pubescent carpels tipped with a curved 
cusp. No described species with blunt merely apiculate carpels 
seems to be related closely to our plant. 
KRaMERIA PARVIFOLIA Benth. Bot. Voy. Sulph. 6, pl. 1 (1844) 
has rather recently been confined, as to range, by Rose & Painter, 
Contrib. U. S. Nat. Herb. x. 108 (1906), to the region of the type- 
locality, southern Lower California. The shrub of northern Mexico 
and the southwestern United States which has passed as K. parvi- 
folia is regarded by these authors as specifically distinct under the 
name K. glandulosa. To this species they seemingly refer all the 
specimens hitherto regarded as K. parvifolia except the material 
from Lower California which is distinguished by the lack of glan- 
dulosity and the greener and somewhat less mucronate leaves. 
They err, however, in this disposition of all of the collections from 
the United States as many specimens are not at all glandular and 
indeed are distinguished from typical material from the region of 
Magdalena Bay only by the shorter, more pubescent leaves and 
usually by the somewhat more compact habit of branching. The 
true relationship of these plants, therefore, would seem to be indi- 
cated best by treating as varieties of the typical form (which, 
indeed, appears to grow only in Lower California) the glandular 
and eglandular shrubs of more northern range. Incidentally, it.
