vitality in the embryo, but may be considered as the natural structure of 
that primary division ; seeds without albumen occurring only in certain genera 
of the paradoxical Aroides, and in some other Monocotyledonous orders 
which are chiefly aquatic. 
5. Doubts may be entertained of the identity of particular species. On this 
subject I may observe, that for whatever errors may be detected in these lists, 
I must be considered as solely responsible; the insertion of every plant con- 
tained in them being founded on a comparison of specimens from the various 
regions of which their existence in the particular lists implies them to be 
natives. The only exception to this being Lipocarpha argentea, of which I 
have not seen American specimens; as a native of that continent therefore it 
rests on the very sufficient authority of Baron Humboldt and M. Kunth. 
In my remarks on the natural orders, I have already suggested doubts 
with respect to certain species included in the lists, and shall here add a few 
observations on such of the others as seem to require it. 
Acrostichum Aureum L. was compared, and judged to agree, with Ame- 
rican specimens; and I have therefore placed it in the 2d list, without, 
however, meaning to decide whether those plants originally combmed with 
A. aureum, and now separated from it, should be regarded as species or 
varieties. 
Fuirena umbellata L. fil. from Congo has its umbels somewhat less divided 
than either the Ameriean plant or that from the continent of India; but from 
specimens collected in the Nicobar Islands, this would appear to be a variable 
circumstance, ; 
Gloriosa superba L. which seems to be very general along the whole of the 
west coast of Africa, is considered as a variety of the Indian plant by M. 
Lamarck. ‘This African variety has no doubt given rise to the establishment 
of the second species of the genus, namely G. simplex, which Linneus adopted 
from Miller ;* and which Miller founded on the account sent to him by M. 
Richard, of the Trianon Garden, along with the seeds of what he called a new 
Gloriosa, brought from Senegal by Adanson, and having blue flowers. 
Miller had no opportunity of determining the correctness of this account ; for 
though the seeds vegetated, the plant died without flowering ; but he added a 
character not unlikely to belong to the seedling plants of G. superba, namely
