he has also annexed Riana, adding a query whether Passura may not belong 
to the same genus. With M. de Beauvois, he refers Ceranthera to Meliacez ; 
and Pentaloba of Loureiro he reduces also to the same order.* Piparea is, 
together with Viola, annexed to Cistine in his Genera Plantarum, and is 
therefore the most correctly placed, though its structure is the least known, of 
all these supposed genera. 
An unpublished genus of New Holland, which I have named Hymenanthera, 
in Sir Joseph Banks’s herbarium, agrees with Alsodeia in its calyx, in the in- 
sertion, expansion, and obliquely imbricate zestivation of its petals, and especially 
in the structure of its antherae, which approach more nearly to those of Violez 
properly so called. It differs, however, from this order in haying five squame 
alternating with the petals; and especially in its fruit, which is a bilocular 
berry, having in each cell a single pendulous seed, whose internal structure 
resembles that both of Violeae and Polygalea, between which I am inclined to 
think this genus should be placed. : 
CHAILLETE. The genus Chailletia was established by M. de Can- 
dolle+- from a plant found by Martin in French Guiana, and which, as appears 
by specimens in Sir Joseph Banks’s herbarium, had been many years before 
named Patrisia by Yon Rohr, who discovered it in the same country. At a 
still earlier period, Solander, in his manuscripts, preserved in the library of Sir 
Joseph Banks, described this genus under the name of Mestotes, from several 
species found by Smeathman at Sierra Leone. Both Dichapetalum and 
Leucosia of M. du Petit Thouars } appear to me, from the examination of 
authentic specimens, to belong to the same genus: and in Professor Smith’s 
herbarium there is at least one additional species of Chailletia different from 
those of Sierra Leone. 
Diphylleia in habit, and in the fasciculi of vessels of the stem being irregularly scattered ; 
essentially in the floral envelope, and in the structure of the ovarium; its stamina, also, 
though numerous, are not altogether indefinite, but appear to have a certain relation 
both in number and insertion to the petals: in the dehiscence of anther, and perhaps 
also in the structure of seeds, it differs from this order, to which, however, it may be 
appended. Nandina ought to be included in Berberidew, differing only in its more 
numerousand densely imbricate bractez,from which to the calyx and even to the petals, 
the transition is nearly imperceptible; and in the dehiscence of ils anthera.
