Arts and Sci., xx., 257-317. 
The first part of this paper by Dr. Gray consists of a critical revi- 
sion of some genera of Borraginece^ made necessary by recent dis- 
coveries. The revisions give us now two species of Oniphalodes. one 
arctic, and one {O- Howardi^ Gray, n. sp.) from Montana and Wash- 
ington Territory, also two species in Western Mexico. A number of 
species of Eritrichium and some of other genera are referred to the 
genus Krynitzia, Fisch. and Meyer, the characters of which are ex- 
tended, and which contains 45 North American species, eight of them 
new to science. Other species of Eritrichium and Echidiocarya 
become Plagiobothrys, Fisch. and Meyer, of which we have 13 rep 
resentatives. Echidiocarya has but a single species, E, Arizomca. 
Under ''Notes on some American vSpecies of Utricularia'' refer- 
ence is made to the drawings of Major Le Conte intended for illus- 
trating his observations on the genus, *and now in possession of Mr, 
I. C. Martindale. U, personafa, Le Conte, is U. junc€a,Y^\\\.\ U. 
iongiciliata, A. DC, and U. siinplex.C Wright, both Cuban species, 
have been detected in Florida; " U. tiibiilaia, L., var, cleistogama, 
Gray, seems to be not uncommon. The late Dr. Garber collected it 
^^ Florida, and Mrs. Owen sends it from the island of Nantucket." 
We may add that it has recently been found again in the New Jersey 
pines by Prof. J. A. Allen. 
Six new genera, each of a single species, are described from the 
Southwest. They are Veatchia {Rhus Veaichiana, Kellogg) from 
Lower California; Lyonotha7nnus from Santa Catalina Island; Prin- 
gleophytum from Sonora; Phanloihamnus of the Phytolaccacese from 
Sonera; Himantostemma, also Sonoran; and Rothrockia oi Southern 
Arizona. The last two genera are of the Asclepiadese. Two other 
"ew species of this order are described, viz : . Lach7iosio77ia Arizoiii- 
^^^n. Gray, and Acerates bifida, Rusby, a very peculiar species with 
^^vo-parted hoods, of which a single specimen only was secured. 
Dr. Gray describes also thirty-nine new species of Gamopetalae 
^d remarks on others. Among the new ones we note Schweinitzia 
^^noldsia from East Florida, and Cassiope oxycoccoides from Behrmg 
island, off Kamtschatka.—N. L. B.
