Heliconia Bihai, Asplenium obtusifolum, Asplenium cristatum, 

 Asplenium serratum, Stenochlaena sorbifolia, Polypodium Phylliti- 

 dis, Polypodium lycopodioides, Dryopteris parasitica, whereas 

 Boehmeria ramiflora, Peperomia scandens together with Araceae 

 cover humid rocks. There occur in the Quill also Coffea arabica, 

 Theobroma Cacao, Spondias lutea and Mammea americana. 

 Northern hilly country. In the northern hilly country the Erio- 

 dendronvegetation is to be found in the ravines and other parts 

 which are not exposed to the heavy winds and where a certain 

 amount of humus is covering the rocks. 



It may easily be recognised here by the great amount of smaller 

 trees and shrubs mentioned on page 282 and 283, whereas the 

 higher trees that are to be seen in the Quill are almost absent. 

 Moreover there is a great quantity of trees, which certainly are 

 not wild here, intermixed with the lower shrubs viz: Tamarindus 

 indica, Melicocca bijuga, Moringa oleifera, Spondias purpurea, 

 Persea americana. 



The species that predominate here in the northern Eriodendron- 

 vegetation are: Rhacoma crossopetalum, Eugenia ligustrina, Eugenia 

 procera, Samyda serrulata, Eugenia axillaris, Trema Lamarckiana, 

 Pithecolobum unguis-catis, Celtis Iguanacea, Guettarda parvifolia, 

 Schaefferia frutescens, Krugiodendron ferreum, Chiococca racemosa, 

 Randia aculeata, Erythroxylon brevipes, Erythroxylon havanense, 

 Pisonia aculeata, Guettarda scabra, Bumelia obovata, Anona muri- 

 cata, Anona squamosa, Rauwolfia Lamarckiana. 

 Here in the northern hilly country no sharp difference can be 

 traced between the Eriodendronvegetation and the Crotonvegetation, 

 nor between the latter and the Vegetation of the rocky slopes of 

 the hills. 



Where this Crotonvegetation begins to change into the Eriodendron- 

 vegetation we see the following plants : Lantana Camara, Lantana 

 involucrata, Croton flavens, Croton ast]"oites, Bernardia corensis, 

 Wedelia buphthalmoides, Melochia tomentosa, Fourcroya gigantea, 

 Vernonia punctata, Stylosanthes hamata, Portulaca oleracea, Pani- 

 cum divaricatum, Melocactus communis. Tragus racemosus, Ruellia 

 tuberosa, Pectis humifusa, Desmanthus virgatus, Sida ciliaris, 

 Justicia sessilis, Commelina virginica, Setaria setosa, Jatropha gos- 

 sypifolia, Opuntia triacantha, Cordia sulcata, Gouania domingensis, 

 Cissus sicyoides, Rhynchosia reticulata, Stigmatophyllon periplo- 

 cifolium, Tillandsia utriculata, Phoradendron trinervium. 

 The are very few herbaceous plants; only in humid localities 

 some species of Peperomia are to be seen.
