Botany of San Miguel_—Edward L. Greene. (Pittonia, i., pp. 
74-93.) 
The island of San Miguel is the most western member of the 
archipelago lying off the coast of southern California, whose flora 
has received.so admirable an exposition at the hands of Professor 
Greene, Mr. Lyon and others. It is a table-land 200 to 300 feet 
high, rising at points, however, to elevations of over 800 feet. There 
is little arboreous vegetation, but evidence is adduced to show 
that Rhus integrifolia was abundant not long ago, as its wood is 
still found in sufficient quantity to furnish a fuel supply to the 
fishermen and seal-hunters who visit the island. The bulk of the 
vegetation is composed of strictly insular species, while the most 
abundant plant is Mesembrianthemum crystallinum, which Prof. 
Greene believes to be indigenous here, as in South Africa. “A 
Catalogue of the Flowering Plants of the Island” enumerates 120 
species and varieties,

Collinsia—A curious.--Edward L. Greene. (Pittonia, i., pp. 52- 
55.) 
Professor Greene records the occurrence of regular corollas 
on Collinsia bicolor, the plant thus showing affinity to Nuttall’s 
genus Zonella. He maintains that the genera are not distinct, 
and refers 7: floribunda, Gray, to the older genus; T. co/linsioides, 
Nutt., is already Col/insia tenella, Bentham.
