454 APPENDIX. No. V. 



In Artocarpeoc, to which Mtisanga belongs, and in Urticece strictly so called, 

 the ovulum, which is always solitaiy, is erect, while the embryo is inverted or 

 pendulous. By these characters, as well as by the separation of sexes, they 

 are readily distinguished from those genera of Cltenopodew and of monosper- 

 mous niecebrew,* in which the albumen is either entirely wanting or bears 

 but a small proportion to the mass of the seed. And hence al.so Celtis and 

 Mertensia,f in both of which the ovulum is pendulous, are to be excluded 

 from Urticeas, where they have been lately referred by M. Kunth. The same 

 characters, of the erect ovulum and inverted embryo, characterise Polygoneae,^: 

 as I have long since remarked, and exist in Piperacew and even in Conifera, 

 if my notions of that remarkable family be correct. But from all those orders 

 Urticeae are easily distinguished by other obvious and important difPerences in 

 structure. 



PHYTOLACEiE. In describing Chenopode*, in the Prodromus Florae 

 Novae Hollandiae, I had it particularly in view to exclude Phytolacca, Rivina, 

 Microtea, and Petiveria, which I even then considered as forming the separate 

 family now for the first time proposed. 



In Chenopodece the stamina never exceed in number the divisions of the 

 perianthium, to which they are opposite. In Phytolacew they are either in- 

 definite, or when equal in number to the divisions of the perianthium, alternate 

 with them. This disposition of stamina in Phytolaceae, however, uniting 

 genera with fruits so different as those of Phytolacca and Petiveria, it would 

 be satisfactory to find in the same order a structure intermediate between the 

 multilocular ovarium of the former and the monospermous ovarium, with 

 lateral stigma, of the latter. 



Two plants in the herbarium from Congo assist in estabhshihg this con- 

 nection. 



The Jirst is a species of Phytolacca, related to P. abyssinica, whose quin- 

 quelocular fruit is so deeply divided, that its lobes cohere merely by their 

 inner angles, and I believe ultimately separate. 



The second is a species of Giseckia, a genus in which the five ovaria are
