2030. Ellen, sister M. The germination of the spores of Conocephalimi conicum. Amer. 

 Jour. Bet. 7: 458-464. PI. S4, 35. 1920.— In this species spores are well developed before 

 September first (in Wisconsin) and during the fall cell divisions take place within them, 6 

 or 8 cells being produced within the spore wall. Winter is passed in this stage. In the spring, 

 cell divisions proceed rapidly until each sporeling develops into a nearly spherical mass of 

 from 30 to 40 cells, provided with chlorophyll and starch. The stalks of the carpocephala 

 now lengthen rapidly; the setae elongate, thrusting the capsules through the calyptra; the 

 capsule walls rupture, and the sporelings are dispersed. Sporelings collected in the fall 

 and sown will develop. By bringing the plants or sporelings indoors and thus subjecting 

 them to artificial conditions the normal developmental stages may be altered somewhat. —

2032. Fleischer, M. [Rev. of: Amank, J., et C. Metlan. Flore des mousses de la 

 Suisse. (Moss flora of Switzerland.) Geneva, 1918 (see Bot. Absts. 4, Entry 1032).] Hed- 

 wigia 61 : (Beiblatt) 34, 35. 1919.— The reviewer criticizes the non-use of Latin in describing 

 new species and enumerates several generic names which he considers untenable. He like- 

 wise thinks that the authors should have adhered less to the old Schimperian classification 

 and have made use of the more natural classification given in Die Naturlichen Pflanzenfamil- 

 ien of Engler and Prantl. — A. W. Evans.

 mosses. Trans. Roy. Soc. South Africa 8: 179-224, PL 11, 12. 1920 (see Bot, Absts. 

 8, Entry 2028).] Bryologist 23: 91-92. 1920.— The reviewer commends the author's careful 

 tracing of the identity of African species with those of temperate regions.— £'. B. Chamber- 

 lain. 



2036. Jaggli, Mario. Contributo alia briologia ticinese. [Contribution to the bryology 

 of Ticino.] Boll. Soc. Ticinese Sci. Nat. 1919: 27-44. 1919.— The author gives a list of 181 

 mosses from the canton of Ticino, Switzerland, based on collections which he made in 1902 

 and later. Full data regarding stations are given under each species, and critical notes are 

 occasionally added. Of the species listed Fissidens Curnowii Mitt, and Cylindrothecium 

 cladorrhizans (Hedw.) Schimp. are new to Switzerland, and 16 other species or varieties are 

 new to Ticino. — A. W. Evans. 



2037. Jaggli, Mario. Una nota inedita di Alberto Franzoni suUe epatiche ticinesi. [An 

 unpublished note by Alberto Franzoni on the hepaticae of Ticino.] Boll. Soc. Ticinese Sci. 

 Nat. 1919 : 19-26. 1919.— The author publishes a list of the Hepaticae known from the canton 

 of Ticino, Switzerland. This list is based largely on a manuscript of Franzoni bearing the 

 date 1869, and for most of the records there are actual specimens in the Franzoni herbarium, 

 now preserved in the museum at Locarno. The species enumerated number 64, of which 48 

 are Jungermanniales and 16 Marchantiales. From a historical standpoint the most inter- 

 esting speces listed is Scapania Franzoniana DeNot., here reduced to synonymy by Meylan 

 and included under S. subalpina var. purpurascens Bryhn. — A. W. Evans.
