952 Progress of Botany in the United States in 1880. [December, 
States,” notices several species, and describes one new one, Wotho- 
lena Lemmoni, from Arizona. The same author’s “Systematic 
Fern List,” a twelve page pamphlet, appeared in September. It 
consists of “a classified list of the known ferns of the United 
States of America, with the geographical range of the species.” One 
hundred and fifty-one species and sixteen varieties are included. 
In “A New Fern,” by G. E. Davenport, in the Bulletin of the 
Torrey Botanical Club, the author describes a new species (Votho- 
lena Grayi) from Southeastern Arizona. A fine plate by Faxon 
accompanies the paper. 
f. Phanerogams. Dr. Gray’s “Contributions to North Ameri- 
can Botany,” published in the Proceedings of the American 
Academy of Arts and Sciences, Vol. xv1, is principally devoted 
to “ Notes on some Composite.” Synopses of species are given 
for the genera Aphanostephus, Chatopappa, Townsendia and 
Erigeron, and important notes are included under Vernonia, Soli- 
dago and Aster. Two new genera, Greenella and Grundlachia, 
and a number of species are described. Six new species of As- 
clepias are noted, and a new genus (Geniostemon) with two spe- 
cies of Gentianaceze are described. Descriptions of miscellane- 
ous species, and of a new genus of Euphorbiacee (Revercho- 
nia) complete this valuable contribution. 
Dr. Gray also published a synopsis of the species of the 
Leavenworthia, in the March Botanical Gazette. 
A most important paper from Dr, Geo. Engelmann, entitled 2 
“ Revision of the genus Pinus, and Description of Pinus Elliott, 
was’published in the Transactions of the Academy of Sciences of 
St. Louis, Vol. iv. The characters of pines are carefully de- 
scribed zz extenso, and upon these a new arrangement of the spe- 
cies is proposed. The characters of the fruit scale serve to. sepa 
rate the genus into two sections, viz: 1. Strobus e Apophys's 
with a marginal unarmed umbo, generally thinner”), and 1. Pine 
aster (‘‘ Apophysis with a dorsal umbo, mostly armed, generally 
thicker”), “The subsections are distinguished by the pe ones 
of the ducts within the leaf.” The description of Pinus Eloi 
a south-eastern species, is all that could be desired, and this 1s 
supplemented by three large and most excellent plates. as 
i In the January Botanical Gazette, Dr. Engelmann described, if | 
full, the northern Catalpa, Catalpa speciosa, which had-previously 
been considered to be C. biguonicides. — | 7 :
