454 APPENDIX. No. V. 
In Artocarpew, to which Musanga belongs, and in Urticee strictly so called, 
the ovulum, which is always solitary, 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 Chenopodee and of monosper- 
mous Iilecebree,* in which the albumen is either entirely wanting or bears 
but a small proportion to the mass of the seed. And hence also Celtis and 
Mertensia,}- in both of which the oyulum is pendulous, are to be excluded 
from Urticeae, where they have been lately referred by M. Kunth. The same 
characters, of the erect ovulum and inverted embryo, characterise Polygonese,+ 
as I have long since remarked, and exist in Piperacee and even in Conifere, 
if my notions of that remarkable family be correct. But from all those orders 
Urticez are easily distinguished by other obvious and important differences in 
structure. ' 
PHYTOLACE. In describing Chenopodez, in the Prodromus Flore 
Nove Hollandiz, 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 Chenopodee 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. [his disposition of stamina in Phytolaceze, 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 mtermediate 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 establishing this con- 
nection. 
The first 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
