often with rays or pores or papillas. Pilites, 

 Agarites, Boletides, Hydnites.

 Clavites. 



1*2. CoiLOGENEs, simple hollow bodies, with 

 cavities, Endosporites, Spungites. 



The difficulties or exceptions to this general 

 arrangement are very few, chiefly arising from 

 some plants not yet well observed or quite ano- 

 malous: Cariea, for instance which has the 

 wood and habit of Palms, with the floral organs 

 nearly like Solarium ! and which is probably a 

 Scarcogene tree. Stated by Hooker to bear 

 fertile seeds without fecundation, as does Morus, 

 and Vitis sometimes, and to afford Fihrine like 

 Animal Flesh, and some Mushrooms. Also 

 Vodostemon with the structure and habit of 

 Fucus, but floral organs like Hippuris and 

 Ruppia, is it also a Scarcogene plant ? These 

 and the Cactides, Euphorbias, Stapelias &lc. 

 evidently indicate one or even two New Series 

 of vegetable evolutions, distinct from those ad- 

 mitted since the discovery of Desfontaine. I 

 claim therefore the merit of having first noticed 

 and indicated those new vegetable forms which 

 I beheve had been overlooked by all Botanists 

 as an organic Series, altho' long noticed as 

 anomalies. 



I invite Botanists to watch their germination 

 and evolution, so as to ascertain their mode of 

 increment. My own observations lead me to 

 believe that it is expansive in Podostemon, 

 Carica, &.c. but partly peripheric in Euphor- 

 bia aud some Cactides, while in Opuntia and 

 Stapelia it is evidently articulated and gemmular 

 as in Ephedra and budding trees. But their 

 wood is totally unlike that of Oaks or concen-
