with scaly buds, and alternate, petiolate, crenulato, persistent leaves. 

 The flowers, also proceeding from scaly buds, and almost always her- 

 maphrodite, are arranged in bunches as in Euptelea, and appear 

 at the commencement of the vegetation of the season. The scaly 

 bracts, which at first protected them, fall off towards the time for 

 their expansion. We can see from the foregoing that this group, 

 to which the name of Trochoden.drecB' has been given, includes two 

 quite degenerate genera of MagnoUacem, with diclinous achlamydeous 

 flowers. The insertion of the stamens in Trocliodendron, and the 

 concave form of the receptacle, which takes away all appearance 

 of independence from the basilar portion of the carpels," might 

 authorize our establishing for these a small group of perigynous 

 Magnoliacece. 



V. CANELLA SERIES. 



The Canellai (figs. 211-215) are plants with regular hermaphro- 

 dite flowers. On the slightly convex receptacle are successively 

 inserted a calyx and corolla of free pieces, an androceum and a gynae- 

 ceum whose elements cohere by their edges. The calyx consists of 

 three free persistent sepals,^ imbricated in the bud (fig. 213). The 



Hooker bad first referred Trocliodendron as an it gives insertion to organs of such complexity as 



abnormal genus. It appears, however, that a the pistil, and that for a good way up, and even 



second species of this genus has recently been near its edges, it becomes difficult to admit that 



discovered in Japan, T. longifolimn Maxim., it is of appendicular origin. If we snj)pose the

de Japon (see Adamonia, viii. 211). and raised a little above the insertion of the 



' Hook. F., loc. cit. stamens, we get a convex receptacle like that of
