the phytoplankton of Wisconsin lakes is presented. The species have been critically studied, 

 and many new observations on life histories and variations are discussed. Keys to all the 

 species are included. The following new species and varieties are described: Crucigenia 

 truncata, Selenastrum Westii, Echinosphaerella limnetica, Tetraedron victorieae var. major, 

 Westella linearis, Volvox mononae, Chlamydomonas epiphytica, C. dinobryoni, Rhizochrysis 

 limnetica, Gloeothece linearis var. composita, Aphanocapsa elachista var. planctonica, Aphano-

 1919. — Notes are presented on distribution of algae found during summers of 1907 and 1909, 

 chiefly on coast exposed to open sea. — A. Gundersen.

 Naturvidenskaberne 56: 1-GO. 2 pi. 1919. — This series of notes deals with the following: 

 The variability of Scenedesmus bijugatus and S. obliquus; the germination of aplanospores in 

 Coelastrum; a list of the freshwater algae of Beeren Island; a change of the name Lyngbya 

 epiphytica Wille to L. Willei Setchell & Gardner; and further study of Agardh's herbarium 

 has led to additional synonyms for Gloeocapsa sanguinea Kiitz., Glaucocystis bullosa (Kiitz.) 

 Wille, Aphanocapsa mucicola (Menegh.) Wille, Gloeocapsa magma Kiitz., Chroococcus auran- 

 tius Wille, and Tetraspora bullosa Kiitz. — E. N . Transeau.

1258. Britton, Elizabeth G. Bahama mosses. Bryologist 24: 17-19. P^ 7. 1921. — 

 A list of the mosses contributed to the Bahama flora, 33 species in 28 genera, is here 

 printed for convenience of reference. Hymenostomum flavescens E. G. Britton is described 

 and figured. — E. B. Chamberlain. 



1259. Brothertjs, V. F. Contribution k la flore bryologique de I'Ecuador. [Contribution 

 to the moss flora of Ecuador.] Rev. Bryologique 47:. 35-46. 1920. — The first part of this 

 paper has already been abstracted (see Bot. Absts. 7, Entry 350). In this second and conclud- 

 ing part 63 species of mosses belonging to 11 families are listed with the usual full data re- 

 garding stations. The families most largely represented are the Hookeriaceae with 17 species, 

 the Hypnaceae with 13, and the Sematophyllaceae with 11. The following species, 15 in all, 

 are described as new: Crossomitrium saprophilum, C. splendens, Cyclodiction Allionii, Hook- 

 eriopsis armata, Lepidopilum Allionii, L. argutidens, L. leucomioides , L. phyllophilum, L. 

 subgracile, Pilotrichum armatum, P. longicaule, Pterogonium liliputanum, Rhynchostegium 

 parvulum, Stereohypnum oxyrrhynchioides , and S. rivulare. — A. W. Evans. 



1260. Garjeanne, A. J. M. Gemmen bei Gjrmnocolea inflata Dum. [Gemmae of Gymno- 

 colea inflata.] Hedwigia 61 : 300-302. 1 fig. 1919.— The author reports the occurrence of 

 gemmae in Gymnocolea inflata, a species which was supposed to lack them. The gemmae 

 are angular, very pale yellowish green bodies, 20-40m in diameter, and composed of 2 unequal 

 cells. They germinate readily and grow in the usual way. The gemmae are borne on the 

 margins of rudimentary pale green leaves and appeared in a dried up culture which had been 

 moistened and thus stimulated to renewed growth. It is questioned whether any of the 

 Jungermanniae are really without gemmae. — D. Reddick.
