220 NATURAL HISTORY OF PLANTS. 
known.’ 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 Lugenistee (or Spartiea), 
in which the seeds are exarillate, and the stamens united into a tube. 
It contains the nine genera, Genista, Spar- 
tium, Laburnum, Calycotome, Adenocarpus, Pet- 
teria, Erinacea, Argyrolobium, and Lupinus. 
The Furze or Gorse (Ulex, Fr., Ajonc) is 
the type of the subseries Ulicinea, which 
also includes the genera Cytisus and Hypoca- 
lyptus. ‘These have the androceum of the 
Lugenistee, the filaments being united into 
a cylindrical tube; but their seeds are 
exarillate. 
The subseries Crotalariee, contains all 
the Genistee 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., Crotalaria, Priotropis, Pentadynamis, 
Heylandia, Dichilus, Melolobium, Anarthro- 
phyllum, Buchenredera, Viborgia, Aspalathus, 
Lebechia, Rothia, Lotononis, Listia, Pleiospora, 
isan Borbonia, Rafnia, and Euchlora. 
sa i a In the little group Lipariee, the leaves 
are simple, the stamens diadelphous (9-1), rarely monadelphous, 
and the seeds arillate ; it comprises the six African genera Liparia, 
Priestleya, Amphithalea, Celidium, Lathriogyne, and Walpersia. 
Bossigee consists of Australian plants, in habit approaching many 
of the Podalyriee, and almost always possessing simple leaves, monadel- 
Bossiaa scolopendra.
