tween it and Pharus, and the modifications that occur in the two 

 species of Leptaspis itself. 



Next follow two remarkable Orchideous plants characterized by 

 Mr. Brown, of which the first, Hexameria disticha, belonging to the 

 tribe of Malaxidece is especially remarkable for the number and mode 

 of attachment of its pollen masses, which are described as " in sin- 

 gulo loculo tres (!), quarum duae inferiores collaterals, tertia supe- 

 rior, omnes apice acuto affixse corpusculo septiformi loculum longi- 

 tudinaliter bipartienti et cum eodem deciduse." The other, Phalce- 

 nopsis, Bl., (Epidendrum amabile, L.) belongs to the tribe of Vandece, 

 and is singularly interesting on account of the size and beauty of its 

 white odoriferous flowers, the curious structure of its labellum, and 

 the mode of attachment of its pollen masses to the stigmatic gland. 

 To the account here given by Mr. Bennett, we may add that it is 

 the " Visco-Aloes 14ta," of Kamel in Ray's ' Historia Plantarum,' 

 App. p. 34, pi. 20, and of Petiver's ' Gazophylacium,' t. 103, f. 10 ; 

 and that it has also been recently found by Mr. Cuming in the 

 Island of Luc on. 



In the ninth article Mr. Bennett describes a species of Freycinetia, 

 a genus distinguished from Pandanus by Mr. Brown, and character- 

 ized by him in the \ Prodromus Floras Novae Hollandise,' but only 

 recently named by M. Gaudichaud in the botanical part of M. Frey- 

 cinet's ■ Voyage autour du Monde.' This genus deviates widely 

 in many respects from the true Pandanus, with which Mr. Bennett 

 compares or rather contrasts it in various essential points, in many 

 of which it approximates the anomalous genera Cyclanthus and Car- 

 ludovica. With respect to the position of the embryo, he corrects 

 an error of M. Gaudichaud, who had both described and figured it 

 as placed at the apex of the albumen instead of at its base. He di- 

 vides the known species of Freycinetia, seven in number, into two 

 sections, corresponding with those of Pandanus, in the one of which 

 the pericarpia are simple and equally coherent, while in the other 

 they are collected into partial phalanges, varying in character in the 

 different species. 



In an article on Podocarpus cupressina, a species first indicated by 

 Mr. Brown in M. Mirbel's paper on the Geography of Conifera, 

 Mr. Bennett adverts to the peculiar character of the genus as given 

 by Mr. Brown in his * General Remarks on the Botany of Terra 

 Australis,' and notices the attempt of M. Achille Richard to invali- 

 date the comparison there instituted between Podocarpus and Dacry- 

 dium. He expresses his surprise that botanists should have concurred
