Ferns of Papua.—Brause? has published a list of Papuan ferns collected 
by LEDERMANN in the expedition of 1912-1913, in connection with a study 
of the Papuan flora by LaurerBAcu. It illustrates how any investigation of 
the tropics increases very materially the number of known ferns. The pres- 
ent list includes 555 species, ee among 43 genera. The following 9 
manes (51), Hymenophyllum ar Alsophila (34), Lindsaya (31), Diplazium 
(31), Aspidium (29), Cyathea (25). ere are described 78 new species, 
Dryopteris including 24, Alsephila 13, Cyathea 7, and Blechnum 7, the remaining 
27 new species being distributed among 12 genera.—J. M 
Gentes Herbarum.—Under this title BarLey’ has begun a new serial pub- 
lication, the first fascicle containing an extensive list of plants which he col- 
lected in China in the spring and summer of 1917. The several localities 
are in central China, and the cultivated plants are not neglected. The col- 
lection includes 20 new species distributed among 13 genera, and 15 new vari- 
eties and forms. There are also transfers and new aneenatione. “The 
ci systematic novelties and taxonomic changes are 44.’ The report con- 
ns also some very attractive photographs of topography and “‘interesting

Seedling anatomy.—HoLpEN," in continuing studies of the anatomy of 
teratological seedlings, has investigated atypical seedlings of Impatiens 
Roylei, an Indian species naturalized in England. One of the two groups of 
these seedlings shows a very complete series illustrating the development of a 
“closely syncotylous condition” from the normal; while the other group 
shows a single cotyledon with no “macroscopic evidence” of syncotylous 
origin. The relation of the facts to the origin of eee : naa 
but a number of alternative conclusions are still in evidence.—J. \ 
amy in Osmunda.—Mrs. Brown” has succeeded in securing apoga- 
mous outgrowths in cultures of Osmunda cinnamomea and O. Claytoniana. 
It is stated that the only reported case of apogamy in this genus is given by 
LEITGEB, presumably using O. regalis. His observations have never been 
confirmed, although investigators since have tried to induce apogamy in this 
species under varied cultural conditions. Mrs. Brown included O. regalis
