19251 MERRILL, THE FLORA OF HAINAN 133 



4-meris, pedicellis 2 ad 2.5 mm. longis, glabris, basi minute bracteolatis ; 

 sepalis late ovatis rotundatis, 0.5 mm. longis, glabris; petalis oblongo- 

 ellipticis, obtusis, 2 mm. longis; filamentis petalis aequantibus, glabris, 

 antheris oblongis 0.8 mm. longis; ovario rudimenti villoso. 



Hainan: south slope of Five Finger Mountains opposite Suimahu 



in forests, W. Y. Chun, no. 2038. 



The alliance of this species is clearly with Evodia malayana Ridley 

 (Fl. Malay. Penins. I. S42 [1922] ), which in turn may prove not to be 

 distinct from Evodia aromatica Blume, differing in its smaller, fewer-nerved 

 leaflets, smaller cymes, shorter peduncles, glabrous pedicels, and its 

 broadly ovate not oblong sepals. It may have been included by Guil- 

 laumin 1 in his conception of E. triphylla DC, but this is unlikely, as 

 Guillaumin's description and the specimens named by him that I have

Sci. 



Bot. vii. 377 [1912]). Evodia triphylla (Lam.) DC. is Melicope triphylla 

 (Lam.) Merr., as I have previously shown, this interpretation being based 

 on an examination of Lamarck's type, a Philippine specimen, in Lamarck's 

 herbarium at Paris. Many of the synonyms cited by Guillaumin belong 

 with Evodia pteleaefolia Merr., but some of them are wrongly placed. 

 Zanthoxylum Lamarckianum Cham. & Schlecht., belongs with Melicope 

 triphylla Merr., the type also being a Philippine specimen, but Evodia

This common and widely distributed species is recorded here merely 

 to call attention to the proper authority for the transfer of Loureiro's 

 specific name Brucea amarissima does not appear in Index Kewensis. 



POLYGALACEAE 

 Xanthophyllum Roxburgh 



GrofTs Hainan record of Xanthophyllum racemosum Chod. was based 

 on McClure, no. 9440, a specimen with immature fruits, following my 

 identification. It is unfortunate that the name should have been printed 

 without its synonym. Xanthophyllum racemosum Chodat is an herbarium 

 name intended to indicate the form described by King and by Ridley as 



iLecomte, Fl. G<5n. Indo-China i. 632 (1911).
