NOTES FOR STUDENTS 
Current taxonomic literature.—O. Ames (Philip. Jour. Sci. Bot. 7:125- 
143. I912),in continuation of his studies on Philippine orchids, lists 54 species 
of the genus Bulbophyllum, tg of which are new to science. —A. BERGER (Monats.

fungus (Pericystis alvei). The fungus grows on the pollen stored in the honey- 
comb.—E. P. BickNELL (Bull. Torr. Bot. Club 39:41 5-428. 1912) ina tenth 
article on “The ferns and flowering plants of Nantucket” records further data 
concerning the Nantucket flora and describes two new cei (Linum intercur- 
sum and Ilex fastigiata) —G. Birrer (Rep. Nov. Sp. 1121-18, 202- 23 9- 
394. 1912) in continuation of his studies in the se hea ti has published several

species of Mamillaria (M. Fcctaaiies), see y indigenous in Mexico.—J. 
Broapuorst (Bull. Torr. Bot. Club 39:357-385. pls. 26-29. 1912) in continu- 
ation of her studies in the genus Struthiopteris records 15 additional species, 3 of 
which are new to science, the others being transfers from Lomaria or Blechnum. 
—N. E. Brown (Kew Bull. 281. rgr2) describes a new genus (Thorncroftia) of 
the Labiatae from South Africa.—E. Cuiovenpa (Ann. di Botanica 10: 383-41 ‘, 
1912) under the title “ Plantae novae vel minus notae e regione aethiopica”’ has 
published several species of flowering plants new to science and proposes the 
following new genera: Spathulopetalum of the Asclepiadaceae and Negria of the 
Gramineae.—T. D. A. CoCKERELL (Torreya 12:244-247. 1912) in an article 
entitled “Tragopogon in Colorado” finds four recognizably distinct forms of this 
genus in Colorado, including a new hybrid (7. porrifoliusxXdubius).—W. G.

II:196, 197. 1912) describes 2 new species of Corydalis from western North 
America.—M. L. FERNALD (Rhodora 14:188-190. 1912) discusses the inland 
loose-flowered roseate form of “hardhack’’and designates it as Spiraea tomentosa 
var. rosea (Raf.) Fern.; the same author (ibid. 192) also characterizes a hitherto 
unrecorded form of ash, namely Fraxinus americana f. iodocarpa Fern.—L. N. 
Gooppinc (Muhlenbergia 8:92-04. 1912) under the title “ New southwestern 
ferns” describes 5 new species and one variety from Arizona, New Mexico, and
