INSULAR FLORAS. 27 



antillana, Aspidospernia sessilijlorum, Solatium hirtum and 

 Pilea ovalis — St. Vincent and Trinidad ; Voyria tenella, 

 Solatium retrofractum and Tillandsi'.i compressa — St. Vin- 

 cent and Jamaica ; Triumfetta grossularicefolia, Erithalis 

 angustifolia and Eupatorium Osscsanum — St. Vincent and 

 Cuba ; Henriettella tri flora — St. Vincent and St. Lucia ; 

 Begonia dominicalis and Stclis scabrida — St. Vincent and 

 Dominica ; Begonia martinicensis and Pleurothallis Jlori- 

 bnnda — St. Vincent and Martinique ; and Echiles circinalis 

 — St. Vincent and Hayti. As already intimated, however, 

 too much weight must not be attached to these data, because 

 further researches may more or less invalidate them ; yet 

 with this qualification they may be accepted as facts for 

 discussion. 



Comparing the number of species of the St. Vincent 

 Flora restricted to the West Indies with Grisebach's 

 estimate (7) for the whole of the West Indies, we meet 

 with a great discrepancy. He came to the conclusion 

 that nearly 50 per cent, of the species that had come 

 under his observation were peculiar to the islands, whereas 

 the components of the St. Vincent Flora include less than 

 25 per cent, of no wider range than the West Indies. It is 

 true there is a very large endemic element in Cuba, and a 

 considerable one in Hayti and Jamaica, but later discoveries 

 have certainly reduced the proportions he estimated, With 

 regard to the number of species confined to each of the 

 principal islands of the chain of islands under discussion, 

 Grisebach's figures are something lower than is actually the 

 case. He enumerates twenty-nine as peculiar to Dominica, 

 probably owing to the absence of material for comparison. 

 For the others his figures are : St. Vincent, 1 2 ; Montserrat, 

 2 ; Grenada, 2 ; Martinique, 2 ; Guadeloupe, 1 ; St. Lucia, 

 1 ; Antigua, 1 ; and Barbadoes, 1. Further investigations 

 have added almost nothing. 



As already mentioned, most of the other British Islands 

 have been botanised by the agents of the Committee, and 

 the results are briefly recorded in the annual' reports, but 

 they contain nothing of sufficient interest for reproduction 

 here. Baron Eggers has published (8) a supplement to
