ANONACEAE 

 Fissistigma Griffith 



Fissistigma hainanense, nom. nov. 



Fissistigma maclurei Merrill in Philip. Jour. Sci. xxm. 241 (1923), non F. 

 maclurei Merrill, op. cit. xxi. 342 (1922). 



Hainan: Five Finger Mountains, F. A. McClure, no. 9733, W. Y. 

 Chun, no. 1606. 



Through oversight the same specific name was used for two entirely 

 different species, so that this change in the name accompanying the second 

 description becomes necessary. 



Popowia Endlicher 

 Popowia pisocarpa (Blume) Endlicher in Walpers Rep. i. 252 (1842) . 



Guatteria pisocarpa Blume, Bijdr. 21 (1825). 



Bocagca pisocarpa Blume, Fl. Jav. Anon. 90, t. 45 (1828). 



Hainan: Fan Ta, southwest slope of Five Finger Mountain, in forests, 

 W. Y. Chun, no. 1918, June 6, 1920. 



The specimen agrees closely with the descriptions of this species and 

 with Blume's plate, as well as with named material available for purposes 

 of comparison. My conception of this species includes Popouria ramos- 

 sima Hook. f. & Th., and the Philippine Popowia polyandra (Presl) Merr. 

 I would call attention to the fact that Gagnepain's interpretation of the 

 genus Popowia includes those forms that Ridley 1 places in the genus 

 Sphaerocoryne Scheffer but I feel absolutely confident that Sphaerocoryne 

 is identical with Melodorum as originally characterized by Loureiro, and 

 that consequently Sphaerocoryne Scheff. is a synonym of Melodorum 

 Lour., while Melodorum of all modern authors is Fissistigma Griff., as I 

 have previously indicated. 2 This interpretation of Loureiro's genus is 

 verified by the type specimen of Melodorum fruticosum Lour, in the 

 herbarium of the British Museum. Synonyms of Melodorum fruticosum 

 Lour., as I understand the species, are Polyalthia aberrans Maingay, P. 

 siamensis Boerl., P. affinis Teysm. & Binn., Popowia aberrans Pierre,
