“ very common on sandy bottoms.” With these several collections 
before me, however, the plant is seen to be nicely distinct from 
the Californian species C. micromeres. The most striking differ- 
ences are its uniformly small size, almost filiform leaves, congested 
fruiting calyces and different nutlets. The groove is so dilated that 
it occupies the larger part of the ventral face of the nutlet. The 
nutlets suggest those of C. Grayi (Vasey & Rose) Macbr. but that 
species has conspicuous flowers and is otherwise different. C. 
filiformifolia does not seem to have crossed the mountains of Lower 
California to the West nor the Sierra Madre of Mexico to the east. 
CRYPTANTHA MICROMERES (Gray) Greene, var. cryptochaeta, var. 
nov., hispida et adpresse strigoso-canescens; nuculis vix muricu- 
latis vel scabridis. — Lower CauirorNnia: San Jose del Cabo, 
March-June, 1897, A. W. Anthony, no. 347 (Typ, Gray Herb.). 
The variety, because of the appressed hairs beneath the spread- 
ing hispid ones, is not green like the typical form of the species. 
In Anthony’s specimen the branches of the inflorescence are not 
nearly so widely divaricate as in typical material and the calyces 
are less densely setose. However, ample collections are needed to 
prove the value of these apparent differences. Accordingly it 
seems better not to give the plant of Lower California specific 
rank at this time.

This seems to be very different from any described species and 
apparently is nearest C. intermedia (Gray) Greene, but the acutely 
angled nutlets with flat ventral surface forbid its reference to any 
of the members of that group. These nutlet-characters suggest the 
group that contains C. orygona (Gray) Greene and C. ramosissima 
Greene, but the plant is obviously not related to these species. 
C. arrinis (Gray) Greene. To the synonomy of this species may 
be added C. geminata Greene, Pitt. i. 119 (1887). The characters
