In the Bulletin of the Torrey Botanical Club (XXX, 1903, pp. 106-108.) 

 W. W. Rowlee has published some notes on the pines of the Isle of 

 Pines, including in these notes descriptions of a new species (Pinus 

 recurvata Rowlee) and a new variety {Pinus cubensis var. anomala 

 Rowlee), also recording the occurrence on the island of Pinus cubensis 

 Grisebach. 



Pinus caribcBa is the common pine which probably formerly covered 

 almost completely the " Mai Pais" gravel plains, the sandy or gravelly 

 (quartzose) plains in the western and southwestern parts of the 

 island, and the gentle slopes and rounded tops of the mica-schist hills 

 and mountains in the south-central and southwestern parts. At the 

 time of the writer's visit in 1910, the view from the top of the Cafiada 

 Mts., looking to the -west and northwest over the pine-barrens, was 

 as over a sea of light green, broken here and there in the hazy distance 

 by the darker green jungle and mangrove forest along the moist valleys 

 and near the coast.
