at the lower levels they are not especially notable. Two species of 

 Schiza?acea3 were common near Port of Spain— a Lygodium sp. and 

 Anemia phyllitidis. 



A visit to a small waterfall a few miles away yielded a considerable 

 number of ferns, including some small Hymenophyllaceae and a Dancea, 

 and also several interesting liverworts. In the botanical garden were 

 also found two interesting liverworts, a large Eiccia and a Notothylas ( ?) . 



While driving to the waterfall a fine white arum (Spathiphyllum 

 canncejolium) was seen in great numbers along the river, and the trail 

 to the falls led through a fine forest with tall trees and a luxuriant 

 undergrowth of large ferns, some of which were small tree-ferns. There 

 were also many Aroids, some of great size — Montrichardia sp., Philo- 

 dendron, Anthurium, etc. Some very showy Bromeliads, with fine 

 scarlet bracts, were common as epiphytes, and also a good many orchids ; 

 but some of the latter were in flower. These, with the gorgeous 

 Warsczewiczia and masses of the fine Heliconia Bihce, made a magnifi- 

 cent picture of tropical vegetation in its most luxuriant aspect. 



Small tree ferns (species of Alsophila and Hemitelia) were fairly 

 abundant, and several young specimens of a Danaea were found on a wet 

 bank, where there was also found a luxuriant growth of several inter- 

 esting liverworts. The latter included species of Aneura, Metzgeria, 

 Symphyogyna ( ?), Fossombronia and Dumortiera. 



In company with Mr. Freeman, assistant director of agriculture, a 

 very interesting excursion was made to the Aripa savanna, some 25 

 miles from Port of Spain. This savanna was in many respects like the 

 one visited in Surinam, but the vegetation was more luxuriant. There 

 were similar groves of Mauritia, but even a finer species (M. setigera). 

 A number of beautiful ground orchids were found in flower, and a 

 small Drosera, different from that found in Surinam, was common. 

 Tiny Utricularias with yellow and purple flowers were abundant, and 

 as in the Surinam savannas, there were clumps of low bushes, largely 

 Melastomaceas and Malpighiaceae, in the shelter of which was found a 

 very interesting fern, Schizcea pennula, as well as several other ferns. 

 Two species of Lycopodium., L. cernuum and L. Carolinianum, weie 

 common. 



The forest adjoining the savanna was very beautiful, with fine 

 palms — Euterpe, Bactris, Attalea, Maximiliana, and others. A Com- 

 melynaceous plant with yellow flowers was very abundant (the same 

 species was also seen in Surinam) and there were the usual abundant 

 epiphytic orchids and Bromeliads, as well as a number of small 

 Hymenophyllaceae. 



In these woods were many specimens of a Clusia, growing first as 

 an epiphyte, and sending down aerial roots, which finally completely 

 strangle the tree upon which the Clusia has fastened itself. These
