connected with some other land area than America, and cites 
many facts which would tend to give weight to this theory. 
“A Catalogue of the flowering plants and ferns of the Island 
of Santa Cruz” enumerates 321 species, more than 25 of which 
_ have not yet been found on the mainland. We find the fol- 
lowing new species in this list: 
Thysanocarpus ramosus ; Hosackia (?) occulta, Bigelovia venata, 
var. sedoides ; Eriophyllum stechadifolium, Lag., var. depressum; 
Cnicus lilacinus ; Stachys acuminata and Typha bracteata, the 
latter a giant of its kind, being 15 to 18 feet high, with stam- 
inate and pistillate spikes 12 to 16 inches long. _ He also makes 
the following changes in nomenclature :—Cardamine integrifolia 
=Dentaria integrifolia, Nutt.) and C. Nuttallit (=D. tenella, 
Pursh.) ; Avrabis filifolia (—Cardamine filifolia, Greene); refers 
the Water Cress to Nasturtium aquaticum, Tragus, 1552; and 
Comarostaphylos diversifolia, (Arctostaphylos diversifolia, 
Parry.) By using the oldest specific name of three other plants 
he gets three additional species: Sisymbrium pinnatum (Eryst- 
mum, WNalt.; S. canescens, Nutt.); Plagibothrys Californicus, 
(Echidiocarya, Gray ; P. Cooperi, Gray); and Distichlis spicata, 
(Uniola, L., D. maritima, Raf.) We presume that this will not 
be acceptable to everybody, and would suggest that it would be 
well to have some conventional rule in the matter, which all 
might follow, otherwise there is sure to be an appalling conflict of 
authority. It appears to the writer that if we are ever to get spe- 
cies correctly and satisfactorily located, we must all follow the 
same usage. This would be a worthy subject for discussion by 
the botanists of the American Association. 
Professor Greene’s paper closes with descriptions of Horkelia 
Kelloggit, (H. Californica, var. sericea, Gray); Horkelia Parryi, 
from Amador County, and Convolvulus Binghamie from Santa 
Barbara. NeEbak.

This valuable publication contains so much interesting matter 
_ that it can hardly be justly reviewed in the limited space at our 
command. Part I treats of work with the students, and indi-
