PSEUDERANTHEMUM sp. 



Odontonema nitidum Merr. Fl. Manila (1912) 437, non 0. Kuntze. 



Commonly cultivated for ornamental purposes in Manila and in other 

 large towns, but not known to produce seeds in the Philippines, Merrill 

 7092, 6345, 7091, Wenzel 1068. Exotic so far as the Philippines are con- 

 cerned, but its origin doubtful; pantropic in cultivation. 



I have not been able to determine the proper specific designation for this 

 species on account of the brief descriptions of numerous horticultural forms. 

 There are three forms common in the Philippines, one with dark purple 

 leaves and branchlets (probably Eranthemum purpureum Hort.) ; one with 

 pale green leaves blotched and mottled with gray or white (probably Eran- 

 themum albo-marginatum Hort.) ; and one with somewhat larger leaves 

 than the other two, varying from pale green to yellowish green and more 

 or less reticulate (possibly P sender anthemum reticulatum Radlk.). The 

 floral characters are the same in all three of these forms.

The locality is unquestionably an error, apparently for Java; Zollinger 

 never visited the Philippines.
