Sprague, T. A., The Genus Nautilocalyx. (Kew Bull. Mise, inform. 



N". 2. p. 85—99. 1912.) 



The genus Nautilocalyx [Gesneriaceae) is revived with an exten" 

 ded scope, so as to include 8 additional species formall}'' referred 

 to AUoplectus and Episcia. It is confined to South America. It 

 differs from AUoplectus in habit and the shape and texture of the 

 corolla, and from Episcia, which it resembles in habit, hy the nature 

 of the placentation. M. L. Green (Kew). 



Stevenson, E. H., Notes on the Vegetation of VVeston Bay, 

 Somerset. (Journ. of Ecology. I. 3. p. 162 — 166. 1 fig. 1913.) 



The locality favours the deposition of sand in one part, mud 

 in another. The distribution of sandplants is described along the 

 shore and from Strand landwards on terraces and low dunes. The 

 Vegetation of the mud-banks is also indicated. Comparison of plants 

 from the two habitats leads to the conclusion that at the same height 

 above high-water mark the sand plant formation is as halophytic 

 as, the mud formation, but in the case of sand the influence of the 

 Vegetation is to raise the altitude quickl}'- so that the features of a 

 maritime plant formation are soon obliterated, whereas in the case 

 of mud the flatter topography is retained with its halophilous 

 species. W. G. Smith.

Clastotypes =i fragments of existing types; specimens cut from 

 plants grown from cuttings or buds of the plant that furnished a

 of plant that furnished a type = spermotypes. Trelease.

Merotype: a part of the individual organism that furnished the 

 type of the specimen of a new species, such part usually contai- 

 ning Organs homologous to those represented in the type specimen.
