lowed by most authors, but Burman f., Fl. Ind. (1768) 104, 

 based his Quisqualis pubescens wholly on the Rumphian Quis 

 qualis, and his var. glabra 1. c. t. 28, f. 2, on Javan specimens. 

 Quisqualis pubescens Burm. f. is thus an exact synonym of the 

 older Q. indica Linn. Poiret, in Lam. Encycl. 6 (1804) 43, 

 referred the Rumphian figure to Quisqualis glabra Burm. f., 

 which likewise is a synonym of Q. indica Linn.

The three forms described by Rumphius are all apparently 

 referable to Psidium guajava Linn., the two forms figured rep- 

 resenting the one with the pyriform fruit (Cujavus domestica 

 Rumph.), the other with the ovoid or ellipsoid fruit (Cujavus 

 agrestis Rumph., the type of Psidium cujavus Linn.). These 

 forms have been recognized by some authors as distinct species, 

 by others as varieties of Psidium guajava Linn. Both figures 

 were originally reduced by Linnaeus, in Stickman Herb. Amb. 

 (1754) 7; t. U7 to Psidium guajava Linn, and t. 48 to Psidium 

 cujavus Linn., the latter figure being the whole basis of the 

 latter species. Following current modern usage both Psidium 

 pomiferum Linn, and Psidium pyriferum Linn, are here con- 

 sidered as synonyms of Psidium guajava Linn.

Psidium cujavillus Burm. f. was based primarily on a Javan 

 specimen, and Psidium pumilum Vahl on one from Ceylon, 

 although both authors cite Cujavillus Rumph. as a synonym, 

 and Burman f . took his specific name from Rumphius. By some
