long considered the type of a distinct group ;' Pliyllonoma? long 

 referred to Celastracea, 3 but differing therefrom in its parietal 

 placentation ; and lastly, Berenice, 4 in floral organization so closely 

 resembling Aryophyllum and Carpodetus. We have thought it right 

 to add a little exceptional genus, Stichoneuron? hitherto held a 

 member of Santalacea. 



IX. BrexietE. — The genera Breccia, Roussea, and Lxerba (besides 

 Aryophyllum) were made by Lindley 6 into the distinct order 

 Brexiacece, allied to Citnoniacea, Celastracece, and Myrsinece. Since 

 then the group has been made, like Cunoniacem, a tribe of Saxi- 



frayacea. 1 We considered in 1865 s that the Brexiece linked 

 PittosporecB with Saxifrayacece, and showed 9 that Anopterus must be 

 placed in the same group as Brexia ; and that lxerba, except in the 

 number of ovules, " has all the external characters and floral 

 organization of a plurilocular Pittosporum."™ This series has the 

 general characters of Escalloniea, but with a free ovary, an almost 

 perfectly hypogynous perianth and androceum, and a single style ; 

 hence we have referred to it the new genera, Abrophyttum n and 

 Cuttsia. 12 



X. Pittospore^. — Considered by us, in 18G5, 13 as Escattoniea 

 with a superior dicarpellary gynaeceum, an imbricate corolla, an 

 isostemonous androceum, a dry or fleshy, free, many-seeded fruit, 

 and indefinite seeds, containing a small embryo near the apex of 

 usually hard albumen. Piffosporacete was made a distinct order by 

 R. Brown 14 in 1814, placed by him near Dilleniacece vxAPolygalacece. 

 Lindley, 15 in 1846, made this group to comprise the eight genera that 

 we retain, and placed it between Vitacece and Olacacece. Endlicher" 5
