Mr. Blake, gardener to James Vere, Esq. raised this plant 

 from seed sent from the Cape of Good Hope, under the name 

 of arborea, and says that he has before known it so called in 

 different collections. We cannot find that it has been any 

 where described, unless it should be the Usvigata of the Sup- 

 plementum Plantarum of the younger Linnaeus, with the 

 description of which, however, it does not correspond in 

 several important particulars. From the odoratissima of 

 Jacquin it differs in the great length of the peduncles, as 

 well as in the leaflets being fewer in number and longer, 

 Flowers in May.
