/hough dispermous are not entirely analogous with those of the lypi 

 cal species of Ulex any more than is the longer polyspermous fruit ot 

 U. genistoides. If however we separate them from Ulex we must 

 coin two new genera, for they agree together only in being different 

 from it , but ihey differ in different ways. Moreover generic sections 

 cannot be so accurately fashioned but that their extremities will vary 

 from the type and lean towards other forms, how numerous soeverthey 

 may be. As the least therefore of two evils I prefer retaining this little 

 group entire since these twojspecics possess the inflorescence, leaves, 

 branches, andfaciesof Ulex, and differ only in having a fruit somewhat 

 more approaching that of Genista. This however is a matter of mere 

 convenience, and I am persuaded that the more minutely we examine 

 natural productions, such is the incessant progression of their chan- 

 ges, the more we shall be induced to separate and distinguish them.

Obs. This is a very variable species, the southern forms of which ap- 

 proach very nearly to G. Canariensis. The principal difference con- 

 sists in the flower-spikes being leafy which is never Ihe case in that 

 species, the flowers too in G. Canariensis are highly fragrant. The 

 utmost limit of the long-spiked southern form of G- candicans is found 

 at Madeira, but after a minute examination I cannot seize upon any cer- 

 tain specific differences, though the plant has altogether another air. 

 This species descends southward as far as Teneriffe where it is of rare 

 occurrence, but altogether similar to the plant of the south of Europe.
