INSULAR FLORAS. 461 



last an ericaceous shrub, common to the mountains of 

 Bourbon and Eastern and Western Africa. Again, many 

 specially African genera are represented by different species in 

 the island and continent. Mr. Scott Elliot's later contribution 

 to the botany of Madagascar (8) contains descriptions of a 

 large number of new species and two new genera, with 

 figures of some of the more striking or interesting species 

 collected by the author, chiefly at Fort Dauphin, in the 

 extreme south-east of the island. There is nothing of a 

 highly novel or peculiar character in this collection, the 

 large majority being new species of genera spread over the 

 whole island. Two species of Tisonia (Bixineae), two of 

 Leptolcena (Chlaenaceae), Quivisia grandifolia (Meliaceae), 

 Calantica lucida, and seven species of Homalium (Samy- 

 dese) ; Lcucosalpa madagascariensis, a new genus of 

 Scrophularinea^ ; Forsythiopsis mistralis, and Camarotea 

 soutensis, a new genus of the Acanthacese ; and upwards of 

 a dozen orchids, are the most noteworthy of this collection. 

 From Mr. Scott Elliot's narrative of his journey (9), from 

 Antananarivo to Fort Dauphin, a few interesting particulars 

 may be gleaned, but there is no attempt at a complete 

 description of the vegetation or analysis of the flora. 



From the foregoing somewhat disjointed account of the 

 flora of Madagascar, it is evident that, although it contains 

 a large endemic element, it is essentially African ; and 

 every extension of exploration in Eastern Africa brings 

 further proofs of the close connection. 



There is one work (37) on the mountain flora of 

 tropical Africa, with full particulars of the distribution of 

 all the species, that I had almost forgotten to refer to, yet 

 it contains a mass of information, including the extensions 

 to the islands. 



Hildebrandt's sketch of the natural history of the 

 Johanna Islands (16) is of the most general kind, and 

 contains no botanical facts of importance. 



I have mentioned Rodriguez in some of my com- 

 parisons, and I may refer (38) to the latest and only full 

 description of its flora. With regard to Bourbon, which is 

 known to possess a strongly endemic flora, the only con-
