he has also annexed Riana, adding a tiuery wliether Passura may not belong 

 to the same genus. With M. de Beauvois, he refers Ceranthera to Meliaceae; 

 and Pentaloba of Loureiro he reduces also to the same order.* Piparea is, 

 together with Viola, annexed to Cistinaj in liis 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An unpublished genus of New Holland, which I have named Hymenanthera, 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 l^anks's herbarium, agrees with Alsodeia in its calyx, in the in- 

 sertion, expansion, and obliquely imbricate aestivation of its petals, and especially 

 in the structure of its antherae, which approach more nearly to those of Violeae 

 properly so called. It differs, however, from this order in having five squamae 

 alternating with the petals ; and especially in its fruit, which is a bilocidar 

 berry, having in each cell a single pendulous seed, whose internal structure 

 resembles that both of Violeae and Polygaleae, between which I am inchned to 

 think tliis genus should be placed. 



CHAILLETE.E. The genus Chailleiia 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 Von Rohr, who discovered it in the same country. At a 

 still earlier period, Solander, in liis 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 D'lclutpetalum and 

 Leiicosia of M. du Petit Thouars j appear to me, from the examination of 

 authentic specimens, to belong to the same genus : and in Professor Smith's 

 herbai-ium there is at least one additional species of Cbailletia 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 antherJE, and perhaps 

 also in the structure of seeds, it differs from this order, to which, however, it may be 

 appended. Sandina ought to be included in Berberidea", differing only in its more 

 numerous and densely imbricate braclea',from which to the calyx and even to the petals, 

 the transition is nearly imperceptible; and in the dehiscence of its antheca?.
