This interesting plant, kindly sent to me by my friend, Prof. 

 MacOwau, has all the characters of Orthosiphon, excepting that 

 of the style, which is here not at all thickened or expanded, but 

 is divided at the apex into subulate branches, exactly as in 

 Tlectranthus or Hyptis. I have here only access to descriptions 

 and to a single figure, that of O. rulicundus, Benth. (Hook. 

 Ic. Plant, t. 459), from the style of which this widely differs. 

 But O. diffiisus, Benth., is characterized as having merely " sty lus 

 obtusus demum breviter bifidus ;" and that may afford a transi- 

 tion to the present species, where the style is bifid with subulate 

 lobes. It differs also from its congeners by its remarkably abbre- 

 viated raceme. The divergences, however, from any other of the 

 Ocimoid genera seem to be greater ; and I venture to place it here 

 for the present.
