the growing- point of Pandanus. Experiments were not made with 

 regard to this point. The leaf arrangement depends on the mode of 

 cell-division in the apex. E. S. Gepp. 



Calyptra-formation on the Sporogonium of Aneura pinguis Dum. 

 — C'h. Benedict {Xotizhl. Kgl. Bot. Gart. Berlin-Daldein, I'JIT. 7, 

 78-80 ; see also Bot. CentralbL, l')is, 37, 214). The record of a capsule 

 of Aneura pinguis in Von Flotow's herbarium, in which the calyptra did 

 not remain at the base of the seta, but had been carried up with the 

 sporogoninm as in mosses. This abnormality has never been recorded 

 hitherto. E. S. U. 



Bavarian Liverworts. — F. Famillee {Denlcschr. Kql. Bayer. Bot. 

 <je>>., 1!)17, 13, n.f. 7, 153-304; see also Bot. CentralbL, 1^)18, 137, 

 215). The object of this paper is to record all liverworts found up to 

 the present in Bavaria, and W'here they occurred. The author includes 

 only authentic records, after a careful personal examination of all collec- 

 tions. Numerous notes on the biology and ecology are interspersed 

 among the records of species. The author divides Bavaria into six geo- 

 graphical areas, and shows the distribution of the species over these 

 areas in a table. He also compares the liverworts of neighbouring 

 countries with those of Bavaria, and shows the richness in species of the 

 latter. E. S. G. 



Hepaticse Baumgartnerianse Dalmaticae. — V. Schiffner {Oesterr. 

 hot. Zeitschr., 1916, 66, 337-53, 13 figs, in text; see also Bot. Cen- 

 tralbl., 1918, 138, 87-8). A treatment of the liverworts of the South 

 Dalmatian Islands. Few species occur in the wooded districts. The 

 stems, however, of bushes in copses are covered with a luxuriance of 

 ■GololejpAinea uiinutissima, and from the branches hang Leptodon, 2\ech>ra, 

 Usnea, and F.ruUania Tamarisci. Few liverworts occur in the 7'ocky 

 districts. Eight species of Riccia are recorded, of whicii R. crijstalJina 

 L. sub. sp. austrigena, from Lagosta, is a novelty. Its principal charac- 

 teristics are very narrow air-spaces, pale grey-green c jlour ; median 

 furrow generally very distinct towards the apex of the frond-lobes ; 

 spores prickly in profile. It is possibly a good southern species. The 

 differences between Riccia Henriquesii Lev. and R. Michelii Rad. are 

 shown in figures. . In the new variety iatermedius of Sphseroearpus 

 texanus the spores occupy a middle position between the type and 

 S. 3IicheUi Bell. The material of Dichiton calycidatum Schiflfn. proves 

 the justice of separating this species from D. galUcum. The position 

 of Dichiton near Lophozia is certainly wrong. The Cephaloziellace^e, a 

 new family of Douin and Schiffner, are most nearly allied to Ptilidiacea^. 

 The former is distinguished from the Trigonanthaceae Spr. principally 

 by the totally different kind of perianth, a character on which Spruce 

 laid most weight. One character, common to all CephaloziellaceaB — 

 namely, that the seta of the sporogoninm is always composed of four cell- 

 series — is found in no other group of liverworts. Rare species which 

 occur on the South Dalmatian Islands are — Soatlibya stillicidioram, 

 Lophozia turbinata, L. lieteropiiylla, Scapania aspcra, Marchesiaia 

 JlacJcayi, Anthoceros dichotomus. E. S. G.
