REVISION OF ROMANZOFFIA. 41 
seen: fruiting pedicels slender, spreading: capsules oval, re- 
markably smooth and shining, not exceeding the sepals. 
This in so far as known rests on a single large specimen de- 
posited in the U. S. Herbarium, and purporting to have been 
collected in Mendocino Co., Calif., in 1875, by G. R. Vasey. Its 
most obvious mark as a species is that of the foliage. It is the 
only Romanzofia seen, in which the wholé’circumference of the 
leaf may be said to lie beyond the terminus of the petiole; for 
in all the rest there is a sinus at base of the blade, so that the 
periphery of it includes more or less of the upper part of the 
petiole. I have noted in the diagnosis that suggestion of the 
obvate which is thus characteristic of this species exclusively. 
On the sheet with this type two smaller specimens are mounted, 
one on either side, both of which show leaves of subreniform 
outline, with nine short lobes, or rounded teeth, and short 
sepals; characters establishing their identity with Æ. Californica. 
10. R. SPERGULINA. Crown of the root tuberiferous, but 
with no hint of the bulbous, the few radical leaves showing no 
dilatation or thickening at base of petiole; plant very nearly 
glabrous, diffusely branching, very slender, the branches 4 to 10 
inches long and apparently procumbent: leaves all very small, 
the lowest and longest not exceeding + inch broad, suborbicular 
and with about 7 broad obtuse shallow lobes; those of the 
branches much reduced, 5-lobed, or even only 3-lobed: racemes 
long and very lax, the rachis almost filiform and bearing small 
bracts with bulblets in their axils interspersed among the flowers: 
pedicels long, filiform, deflexed in fruit: corolla less than } inch 
long, with a distinct cylindric tube as long as the calyx, and an 
open-funnelform limb: capsule small, long-ovoid, twice the 
length of the small calyx. 
Known only in specimens from Pilarcitos Creek, San Mateo 
Co., California, collected 20 April, 1895, by Mr. J. Burtt Davy. 
In a Hydrophyllaceous genus of which the type species so 
closely resembles a saxifrage that the specimens are often 
found in the herbaria under Saxifraga, this latest new one is
