NEW GENERA OF HIMALAYAN PLANTS. 381 



do, that they are peculiarly interesting both in a structural and syste- 

 matic point of view. The genus Maddenia^ in particular, is quite ex- 

 ceptional in its Order^ from presenting apparently normally dimorphous 

 flowers, a feature that has not hitherto been recorded amongst Rosacers. 



DlplarcJiey which is an undoubted Ericeous plant, and in many re- 

 spects more closely allied to Loiseleuria procumhens. than to any plant 

 of the Order, differs from the majority of the family in the dehiscence 

 of the anthers, aud from all in the two series of stamens, of which the 

 outer or upper series is epipetalous, and the lower sometimes epipcta- 

 loiis, but more frequently hypogynous. 



In the name Maddenia we are desirous of commemorating the bota- 

 nical services of Major E. Madden, of the Bengal Artilleiy, a well-known 

 and most valuable contributor to our knowledge of Himalayan plants.
