more common in the coast counties of California than in the Old 
World. The only European specimen that we have been able to use 
for comparison is one collected by С. Davies in Ashdown Forest, 
Sussex, England, in 1881, which we owe to the generosity of 
Matthew В. Slater, Esq., of Malton; this unfortunately lacks ma- 
ture perianths, yet the correspondence of the Californian plants 
with it, so far as it goes, and with the detailed description of 
the species given by Dr. Spruce is so close that we have no 
ground for doubting their specific identity. A slight difference 
possibly lies in the more frequent occurrence in the Californian 
specimens of concrescence on both sides between bracteole and 
bracts, forming a complete cup with an erect acutely lobed limb, 
yet Spruce says of the specimens collected in Ireland by Lindberg, 
“bractae intimae cum bracteola biloba in excipulum alte connatae ” ;* 
on the other hand, the bracteole in our plants is sometimes free on 
one margin and the bracts may even be found, though very rarely, 
to be quite distinct dorsally. 
The collection of this species in San Diego County by Mr. 
Koch suggests that it probably occurs also in the intervening coast 
region.

_ Plants medium-sized, depressed-caespitose, light green, some- 
times darkening on drying. Stems prostrate, or ascending at the 
Pen gemmiparous apices, subsimple or with irregularly disposed 
branches, these, with rare exceptions, arising somewhat laterally 
from the axils of the underleaves; root-hairs very long, usually 
numerous, springing in clusters from the base of the underleaves. 
ves alternate, incubous, plane or slightly convex, oblong, ovate, 
or subrhomboida], rounded or retuse at the apex, less commonly 
acute, bidentate, ог bilobed, the margins entire; leaf-cells rather 
large, chlorophyllose or pellucid, rarely with trigones. Under-
