REVISION OF ROMANZOFFIA. 35 
a revolution complete in people’s treatment of those genera, 
namely, that the several species fall naturally into two strongly 
marked groups upon characters vegetative rather than carpo- 
logical. 
I consider it strange that no author has mentioned it, that the 
original species of Romanzoffia, both of them, are loosely though 
not indistinctly bulbous at base, by the crowding together of 
the dilated and fleshy-thickened bases of the basal petioles. The 
character is well enough brought out in the figure by Bongard, 
and is as manifest in all the northern and subalpine species. 
Even the branches, in the more robust species, exhibit at their 
lower nodes, where a number of leaves develop, the same loose 
bulb, and it is not to be doubted that in such cases these bulbs 
at last take root and form new plants. 
Only in the Californian species does this bulbous character 
fail, and it fails utterly; the propagation, except by seed, being 
effected by means of small axillary bublets, as in certain saxi- 
frages. I think that not one of the three Californian Roman- 
20ffias will be found to be of more than annual duration; the 
long dry season there, succeeded by a moist cool growing season 
instead of winter, inducing reproduction by bulblets from year 
to year, in place of the bulbous-perennial duration of the species 
subjected to a very long cold winter and a short wet summer.

forked below the middle and with a leaf at the fork, the raceme
