Bancroft, N., Note on Vegetative Reproduction in some 

 Indian Selaginellas. (Ann. Bot. XXVIII, p. 685—693. 49 pl. 

 7 Textfig. Oct. 1914.) 



Two species were investigated , Selaginella chrysocaulos Spring 

 and S. chrysorrhisos Spring. Both are reproduced vegetatively bj^ 

 tubers. In S. chrysocaulos the tubers are superficial and attached to 

 the subStratum by well developed ventral rhizophores; the dorsal 

 rhizophores are functionless and much reduced; the leaves of the 

 tubers, though differing somewhat from those on the ordinary stem 

 are well developed and provided with Chlorophyll. In 5. chrysor- 

 rhisos some of the branches of the stem penetrate Underground; 

 their apices become enlarged and bear crowded, colourless, scaly 

 leaves devoid of Chlorophyll. The axis of the tubers contains very 

 little vascular tissue; it branches dichotomously and in each case 

 produces at right angles to this plane of division a dorsal and a 

 ventral branch, the rudimentary dorsal and ventral rhizophores that 

 have lost their funcLion owing to the subterranean position of the 

 tubers. Their epidermal cells grow out into hypha-like filaments. 



In both species the anatom}'^ of the tuber is the same as in the 

 ordinary stems of the forms of the monostelic group to which thej' 

 belong. Isabel M. P. Browne.

 Howe Island. (Proc. Linn. Soc. N. S. Wales. 1914. XXXIX. 2. 

 N". 154. p. 257-262. Sydney. Sept. 1914.) 



The author publishes descriptions of Polystichiini Whiteleggei 

 sp. n., and P. Moorei Christ, var. tenermn var. nov., and clears up 

 the confusion of these ferns. He discusses the indigenous species 

 of Dryopteris and Marnttia. The specimens of Ophioglossum found 

 in the Island he refers all to O. vulgare var. lauceolatum , a variable 

 plant. He redescribes Alsophila robusta C. Moore, and quotes in 

 füll R. B. Oliver's careful field-notes of the four tree-ferns found 

 in the Island, showing the nature of their trunk, stipes, rhachis , 

 costae, etc. A. Gepp.
