L, obtusaj MiilL Arg., is so uearly allied to L, capenm, Miill. Arg., that it 

 may prove on closer field-study to be an ecological state of the latter species 

 within which it has, so far as mere description goes, been included by Sprengel, 

 Sender, Baillon, Bentham and others. The two are, h»»wever, so distinct a^'^ 

 regards facies that L. obtusa has hardly ever been distributed as Z. capensisj 

 the practice has been to issue it as Adenocline procumhenSf fruiii which it 

 differs widely in floral charactei^, but which it resembles in general 

 appearance.
