Brucea luzonensis Vidal, Sinopsis, Atlas, 19 t. 21. f. B. 1883. 



The original description of this species, which is not listed in Index 

 Kewensis, nor in the first or second supplement to that work, is as follows: 

 "Arbol. Hojas con 4 pares de hojuelas festoneado-aserradas, obliquas, pecio- 

 ladas, finamente vellosas en el env6s, 0.1 m. de longitud. Flores con caliz 

 y corola apenas empizarradas en la base; petalos lineales, verdes, reflexos 

 en el Spice; anteras rojas. Infloresencia en racimos axillares, cortos. 

 Afine a la B. glabraia Decne., de la cual difiere en nlTimero y tamauo de 

 las hojuelas asi como en la infloresencia. Hallada con flores en Enero." 

 Vidal's specimens were from Mariveles, Province of Bataan, Luzon, but he 

 does not mention the material in his Revision. 



The validity of this species is very doubtful, it being apparently only a 

 form of Brucea sumatrand Roxb. It is apparently represented by No. 987 

 Cuming, in Herb. Govt. Laboratory, and the following specimens, all from 

 Luzon: Province of Bataan (181, 480, Whitford), May, July, 1904; I 2608, 

 2799, 2800 Meyer), February, 1904, and March, 1905; (1766. 2750 Borden), 

 August, 1904. and March, 1905; (6165 Leiberg), July, 1904; (6786 Elmer), 

 November, 1904. Province of Rizal, Bosoboso (1151 Ahern's collector), 

 June, 1904. This species is common at Mount Mariveles, growing in 

 the forests at from 30 to 1,000 m. above the sea, the material cited above 

 being exceedingly variable, especially in vegetative characters. No. 987 

 Cuming is cited by Turczaninow ' as being very close to Brucea sumatrana, 

 and half way between that species and B. glabrata Decne. Apparently 

 typical B. sumatrana Roxb. is represented by No. 512 Ahern, Surigao, 

 Mindanao, and No. 30 DeVore and Hoover, Island of Basilan, but Brucea 

 luzonensis Vidal seems to gradually pass into the former species. If the 

 Luzon form is to be retained as distinct, Vidal's specific name should be 

 adopted, but I am of the opinion that abundant material will only more 

 closely connect the species with Brucea sumatrana Roxb.
