530 Taylor. Endemism in the Bahama Flora. 



DicJiromena has only one other Bahamian species, D. colorata, which is 

 widely distributed both throughout the archipelago, on the mainland, 

 and in the larger West Indies. It is found on Inagua, and must be 

 the parent or source of the endemic D. inagiiensis. 

 Agave has eight native species in the Bahamas, all endemics, which are 

 scattered over the archipelago thus : 



A. inagiiensis on Little Inagua and on Caicos. 

 A. bahamana on several islands, all on Great Bahama Bank. 

 A. Mil/spang/iii, confined to Great Exuma. 

 A. cacozela, confined to New Providence. 

 A. acklinicola, confined to Acklin Island. 

 A. indagatorum, confined to Watlings Island. 

 A. Braceana, on Abaco, Great Bahama, and doubtfully on Andros. 

 Encyclia has eight species in the Bahamas, with only one other endemic, 

 E. ba/iamensis, which is found nearly throughout the archipelago 

 and also on Inagua. E. diurna and E.plicata, both widely distributed 

 in the Bahamas and elsewhere, are also found on Inagua. It is diffi- 

 cult to avoid the conclusion that from these three Encyclias, known 

 to grow on Inagua, the endemic E. inagiiensis has been derived. 

 Heliotropium has ten species in the Bahamas, of which five are endemic. 

 Of these endemics only two others are known on Inagua, while three 

 common Bahamian Heliotropiums are also found there. 

 Lantana has six species in the Bahamas, two of which are endemic. 

 L. demntata is an endemic confined to the islands on the Great 

 Bahama Bank. On Inagua are recorded L. Camara and L. involu- 

 crata, from the latter of which L. balsamifera may be safely assumed 

 to have been derived, as it is a plant of wide distribution nearly 

 throughout the West Indies. 

 Nashia has only a single species in the Bahamas, the endemic 

 N. inagiiensis, confined to that island. Two other species are known 

 in the larger West Indies. 

 Gucttarda has six Bahamian species, with all its three endemics confined 

 to Inagua. The other three species, all found on Inagua also, are of 

 wide distribution both in the Bahamas, the Florida mainland, and in 

 the West Indies. 

 Emodea has aix Bahamian species, four of which are endemic. Two of 

 these endemics are unknown on Inagua, but E. littoralis, a species 

 of wide distribution, is common there. E. Nashii and E. Taylori 

 must have been derived from it, for these comprise all the Ernodeas 

 known on the island. 

 Borreria has eight species in the Bahamas, six of which are endemics. 

 Of these endemics B. savannarum and B. baJiamcnsis are found on 

 Inagua as well as other islands, while the only widely distributed 

 species found on the island is B. lacvis.
