assume the form of birds ia the axils of barren branches, Bryuni 

 atropuvpureum has tubercles or bulbs in the axils of leaves. On 

 the leaves of OrthotricJmm Lyelli grow little strings of cells, which, 

 presenting a confervoid appearance, were named Conferva eas- 

 tanea. It has since been demonstrated that these conferva; are 

 but an intermediate stage of mosses. Oncopliorus glaucus has a 

 great number of cells forming a dense mass at the tip of the 

 leaf; these, in the damp season, give rise to numbers of young 

 plants ; hence this plant is common in countries where it is not 

 known to fruit. The subject of the growth from gemmse had not 

 been thoroughly investigated ; he purposed studying the pheno- 

 mena, when he hoped to lay before the Society some new facts. 

 The paper was illustrated by drawings and microscopic objects 

 prepared by Mr. Smith, which were exhibited afterwards by the 

 following gentlemen, the most striking being by Mr. Hennah : — 

 Innium cuspidatum, hermaphrodite flowers, showing archegouia, 

 antheridia, and paraphytes ; Innium Hormim aud Polytrichum 

 commune, showing (^ flowers ; Neckera oligocarpa $ flowers, con- 

 sisting of Archegonid and Paraphytes. 



Mr. Sewell. — Pottia carifoUa section of leaf, exhibiting layers ; 

 Orthotriclncm Lyelli, with confervoid gemmae with leaves, this is 

 the Conferva castanea of the early botanists. 



Mr. Wonfor. — Aulacomnion androdi/um, showing gemmae or 

 pseudospodia ; Ullota pihyllantlia, with gemmae on the tips of the 

 leaves, and forming aggregate cells ; and Tetraphis pellucida, in 

 which the gemmae were enclosed in a lenticular bud.
