NATURAL HISTORY OF PLANTS. 



Bossiaa scolopendra. 



known. 1 The leaves are simple, trifoliolate, or more frequently uni- 

 foliolate ; their stipules are ill-developed, or even altogether absent. 

 The flowers are white or yellow, forming simple or compound racemes 

 or spikes, sometimes short and capituliform ; they are accompanied 

 by bracts and bractlets, leafy and persistent or small and caducous. 



This genus gives its name to the group Eugenistece (or Sparticce), 

 in which the seeds are exarillate, and the stamens united into a tube. 



It contains the nine genera, Genista, Spar- 

 tium, Laburnum, Calgcotome, Adenocarjms, Pct- 

 teria, Erinacea, Argyrolobium, and Lupinus. 



The Furze or Gorse {View, Fr., Ajonc) is 

 the type of the subseries Ulicinece, which 

 also includes the genera Cyf/sus and Hypoca- 

 lyptus. These have the androceum of the 

 Eugcnistece, the filaments being united into 

 a cylindrical tube : but their seeds are 

 exarillate. 



The subseries Crotalariea, contains all 

 the Genistea which have no aril, and in 

 which the tube formed by the filaments of 

 the monadelphous stamens is short down 

 the back. It contains eighteen genera, 

 viz., Grotalaria, Priotrqpis, Pentadynamis, 

 Heylandia t Dic/iiltis, Melolobium, Anarfhro- 

 phyllum, Buchenroedera, Vihorgia, Aspalathus, 

 Lebeckia, RotMa,Zotononis, Listia, Pleiospora, 

 Borbonia, Iiafnia, and Eucldorn . 



In the little group Lipariea, the leaves 

 are simple, the stamens diadelphous (9-1), rarely monadelphous, 

 and the seeds arillate ; it comprises the six African genera Liparia, 

 Priestleya, Amphithalea, Ccelidium, Lathriogyne, and 7J~a/pr,:sia. 



Bossiaetf consists of Australian plants, in habit approaching many 

 of the Podalyricce, and almost alwa}^s possessing simple leaves, monadel-
