Polyalthia lateriflora (Blume) King, a species originally de- 

 scribed from Javan material, now known from the Malay 

 Peninsula and Java, and the very closely allied Polyalthia 

 zamboangensis Merr., of Mindanao. Cananga silvestris II angus- 

 lifolia Rumph. is the whole basis of Uvaria ligularis Lam. and 

 of Unona ligularis Dunal, and Lamarck's specific name may 

 prove to be the oldest for the plant now known as Polyalthia 

 lateriflora King. In the absence of material from Amboina re- 

 presenting Rumphius's species, however, it is considered advis- 

 able to defer the actual transfer of Uvaria ligularis Lam. to 

 Polyalthia, although the species manifestly belongs in the latter 

 genus. Linnaeus reduced it, by error, to Uvaria zeylanica Linn., 

 in Stickman Herb. Amb. (1754) 10, Amoen. Acad. 4 (1759) 

 121, including also Cananga silvestris I trifolia, which is figured 

 on the same plate, but neither of which remotely resembles 

 Uvaria zeylanica Linn., a species known only from India and 

 Ceylon. 



POLYALTHIA sp. 



Guatteria rumphii Blume ex Henschel Vita Rumph. (1833) 153 

 (type!). 



Arbor nigra parvifolia Rumph. Herb. Amb. 3: 10, 11, t. U, f- 2; t. 5. 



The plant figured and described is certainly a Polyalthia, but 

 its status cannot be definitely settled without material from Am- 

 boina. It is the whole basis of Guatteria rumphii Blume as 

 published by Henschel, by citation of Rumphius, as indicated 

 above, a name that has been entirely overlooked, and one that 

 is not included in Index Kewensis. Linnaeus reduced, with 

 doubt, both t. U and t. 5 to Uvaria zeylanica Linn., in Stickman 

 Herb. Amb. (1754) 11, Amoen. Acad. 4 (1759) 122, but neither 

 figure presents anything in common with this species. Hasskarl, 

 Neue Schliissel (1866) 46, quotes Teysmann's opinion that Arbor . 

 nigra parvifolia Rumph. represented Artabotrys suaveolens 

 Blume, a species with which neither the description nor the 

 figure agrees. 



Arbor nigra maculosa Rumph. Herb. Amb. 3: 12, t. U, f. 1, is 

 probably one of the Annonaceae, possibly a species of Polyalthia. 

 It is certainly not Artabotrys odoratissimus Blume, where it 

 was placed by Henschel, Vita Rumph. (1833) 153. 



Arbor nigra latifolia Rumph. Herb. Amb. 3 : 12, is probably some 

 annonaceous plant, but its status must await a more exhaustive 

 botanical exploration of Amboina. No reduction of it has ever 

 been suggested.
