occur in St. adnatum, in which there is a single anterior carpellum, 

 or if two carpella are present the anterior only is fertile, the ovula 

 being always attached to the posterior angle of the cell. He de- 

 scribes the carpellum oilsopogon and Leucospermum among Proteaceee 

 as anterior ; and notes that in Grevillea the carpellum always alter- 

 nates vdth the two larger sepala, but varies most extensively with 

 reference to what he considers the axis. \n Anadenia he states that 

 the carpellum is always anterior in the lower half of the raceme, 

 but varies in position towards the summit, and in rare instances is 

 perhaps even posterior. In some species of Acacia also he believes 

 that he has found instances of posterior carpella, but as the flowers 

 were for the most part in threes, these carpella might belong to the 

 lateral flowers. In Pedicularis palustris he has always found the 

 anterior carpellum and the anterior division of the style larger than 

 the posterior; and the same is the case with Mendozia, resulting in 

 the latter instance in the suppression of the posterior carpellum in 

 the fruit. He gives at length his reasons for regarding the carpellum 

 as anterior in Casuarina, Cannabis, Hiimiilus, Parietaria, Urtica, Ela- 

 tostemma and Celtis ; and he concludes his remarks on the Protero- 

 carpous division by some observations on Ciiphea and LytJirum ; on 

 Magallana ; and on Fumaria. 



Under the head of the Heterocarpous division he begins by recur- 

 ring to the relations already mentioned as existing between Cerato- 

 phyllum, PiperacecB, Houttuynia and Chloranthtis. He then proceeds 

 to notice Gentianeas, among which he states that the dichotomous 

 Erythreea linarifolia is an example of the two carpella being anterior 

 and posterior, and infers from thence and from other variations, 

 taken in connexion with the general statement that in this family 

 the carpella are right and left, that their position (as in Apocynece 

 and LoganiacecE, according to M. Alphonse DeCaudoUe) is variable. 

 He next refers to Broussonetia and Morus and to Stilbe, which latter 

 he is disposed to consider as related to Empetrece and Euphoi-biaceee, 

 and then proceeds to the examination of Cupuliferce, among which 

 he finds extensive variations. He refers to Coriaria as agreeing 

 with MalpighiacecB in having its raphe turned away from the 

 placenta and consequently next to the dorsal rib of each carpellum, 

 which he describes as corresponding with the general position of 

 the funiculus in that family. He describes the carpella of Mirabilis 

 as being all lateral and internal ; and again notices the peculiarities 

 which he had before referred to in the position of the funiculus in 

 ChenopodeoB, AmaranthacecB and Illecebre<E, adding some remarks on 

 the carpella of Polygonece and Alsinece. He indicates certain cha-
