EXCLUDED SPECIES 



Aglaonema modestum Schott ex Engl, in DC. Monog. Phan. 2 (1879) 

 442, Pflanzenreich 64 (1915) 29, /. 13. 



The type of this is a specimen collected by Gaudichaud supposedly 

 in Luzon, but which in all probability came from Macao; the species occurs 

 in southern China, but has not been detected in the Philippines. See 

 Merrill in Philip. Journ. Sci. 13 (1918) Bot. 133. 



Aglaonema pictum Kunth; Naves Novis. App. (1882) 291. 



Aglaonema simplex Schott; Naves Novis. App. (1882) 291; ? Vidal Rev. 

 PI. Vase. Filip. (1886) 281. 



Vidal's doubtful record for this Bornean species was based on his No. 

 1996 from San Mateo, Rizal Province, Luzon. I have not seen the spec- 

 imen but suspect it to be the same as A. haenkei Schott or A. oblongif olium 

 Kunth.
