in separating these genera from the true pines, and associating them 

 with the yew. " That their true position," he says, " is in the Abie- 

 tine section of the family was pointed out to me by Mr. Brown when 

 placing in my hands the specimens now described. Not only do 

 their inverted ovula bear the same relation to the supporting scale 

 as in the genera of that group, but we even find in Araucaria an 

 analogous structure as regards the confluence of the scale with the 

 envelope of the solitary ovulum. Thus Podocarpus might be regarded 

 as an Araucaria reduced to a single fertile scale, or at most to three 

 such scales, were it not that in the latter there exists, as far as we are 

 yet aware, but a single envelope of the seed, while in the former its 

 coats are double." Mr. Bennett refers to the structure of the male 

 organs, and especially of the pollen, as confirmatory of this arrange- 

 ment, the pollen of Podocarpus and Dacrydium being perfectly iden- 

 tical in structure with that of all the species of Pinus, (with the sin- 

 gle exception of the Larch,) while that of the Cupressince, (including 

 Taxus) is altogether different and equally remarkable ; " the sphe- 

 roidal form of its grains, together with the singular mode in which 

 their outer coats are ruptured and thrown off, in consequence of the 

 great capacity for absorbing moisture possessed by the mucous mat- 

 ter surrounding the inner," having been some years ago pointed out 

 to him by Mr. Brown as readily distinguishing that section from the 

 greater portion of the true Conifera. He then proceeds to notice 

 the successive additions made to the genus Podocarpus, which now 

 consists of four or five and twenty species, divisible into four distinct 

 and strictly natural sections, distributed over all the great geogra- 

 phical divisions of the globe, Europe alone excepted, and extending 

 in latitude from the equator to Japan northward, and to New Zea- 

 land in the south. These sections he characterizes, and enumerates 

 under each the names of the species referrible to it, as far as they are 

 known to him by his own examination, or by sufficient figures and 

 descriptions. 



Bragantia tomentosa, BL, forms the subject of the eleventh article, 

 in which Mr. Bennett also notices the other species belonging to the 

 genus, and adverts to the more essential modifications occurring in 

 their structure. He refers to the genus Trimeriza of Professor 

 Lindley, which he is of opinion cannot be distinguished from Bra- 

 gantia, the characters relied upon for its separation being equally 

 found in the original species to which the latter name was first ap- 

 plied, and being he thinks of too small importance in so limited a 

 group to justify the severing of these from the remaining species. 

 He points out the relations of Bragantia to Asarum, Aristolochia and
