Of this very polymorphous species, several distinct forms seem to occur. 

 The most common form is a small shrub, reaching a height of 1 " 2 and 

 a breadth of 2 M. Its inflorescences have a diameter of 2— 2 , / 2 cM., 

 whilst the colour of the flowers varies from bright yellow and orange 

 to dark-red. We found, however, in the mountains N. W. of Gadok, N. of Ml 

 Gedeh, W.-Java, a form of larger size (2'/ 2 M. in height, 3—4 M, in diam.), 

 with larger inflorescences (3—4 cM. in diam.) and larger flowers, the colour 

 of which was white or very pale rose with a white or pale-yellow throat. 

 The limb of the corolla was 0.7 — 0.9 cM. in diam. (in the common form 

 0.4 — 0.5 cM.), the stems spinous. According to an oral communication by 

 Mr. BACKER more forms of this species occur in Java, all of them more 

 or less constant. Concerning this we may refer to his paper about Lantana 

 in „De Tropische Natuur", II, 27 and 33 (1913), where details are given.
