Luzon Is]., Prov. Isabela, Malimii (Ware. n. 11784). 



A species allied to Fagara teiraspermum Wight et Aru. 

 but with differently shaped leaves. 



Enoler in Pflanz.-Fam. 3, IV (1897), p. 115 has separated 

 the genus Xanthoxijliun into Fagara and Xanthoxglmn in a 

 narrower sense, thus reestablishing the old Linnean genera. 

 He gives as his reasons for so doing, that however variable 

 the flowers of Fagara are as to the number of their parts, 

 the sepals, petals and stamens always alternate. It is true 

 that in Xanthoxglum also the stamens alternate with the parts 

 of the perianth, but here the parts of the perianth belong to 

 only one series of floral organs („ Formation") and cannot be 

 considered on account of their alternation with the stamens 

 as sepals that remain after the abortion of the petals. The 

 flowers of the true Xanthoxyliini represent, so far as the 

 perianth is concerned, a very primitive type, which otherwise 

 does not occur in the family and cannot bo derived from the 

 Fagara type. Turczaninoff Bull. Soc. Imp. de Moscoii XXXVI 

 (1863), p. 597 describes Zanthoxglum? tripUnerve as having 

 simple leaves, 5 sepals and 5 petals. Simple leaves not being 

 found in this genus, the plant is not a Xanthoxylimi. Turcza- 

 mnoff's plant is evidently not yet accounted for. He writes 

 1. c. „Insula Luyon, in provincia North Hows, Cumixg coll. suppl. 

 no. 2". A province of this name does not exist in Lu9on. 

 May not the plant perhaps come from Lord Howe's Island? 

 I am not aware that Cuaiing collected on this Island. The 

 matter is therefore as yet entirely unexplained.
