Climbing over the herbs and other plants, Plumbago scandens L. 

 forms an element in the roadside vegetation. 



The plants of the highways leading into Port-au-Prince, the 

 capital of Haiti, differ materially from those collected along the 

 roads on the north coast. The following plants were found along 

 the southwestern suburban roads, viz., Cordia serrata (L.) Giirke., 

 Commelina Virginica L., Relates iimbellata Jacq., Ec/iites Neriandra 

 Griseb., Wedelia Elirenbergii Schlecht., Sida acuta Burm., Parthe- 

 nium Hystcroplwrus L., Spermacoce laevis Lam., Barleria lupidina 

 Lindl., Acalypha alopecuroidea Jacq., Bouchea Elirenbergii Cham., 

 Leucaena glauca Benth., Cassia sericea Sw., Moringa pterygosperma 

 Gaertn. Moinordica Charantia L. is the only climbing plant 

 gathered and it is extremely common, growing over other plants 

 and the fences. Higher up on the hillsides along the bridle-paths, 

 Acacia macracantha H. & B. and Bauhinia variegata L. occur in 

 the thickets. 



The plants found by the writer in the streets of Aux Cayes on 

 the south coast of Haiti are worthy of mention in connection 

 with the enumeration of the above wayside species. Aux Cayes 

 lies on a restricted, low-lying coastal plain and during heavy 

 rains the streets are flooded with water. Argemone Mexicana L. 

 and Lantana Camara L. are common weeds. Cleome spinosa 

 Jacq., var. pungens Willd., Cassia occidentalis L., Solatium mam- 

 mosum L., and Malachra sp. are typical ruderal plants. The old 

 moss-grown walls of deserted buildings are covered with patches 

 of a small herb, Pilea microphylla Liebm., while growing in the 

 marshes near the principal wharf, the white mangrove, Laguncu- 

 laria racemosa Gaertn. and a sedge, Fimbristylis ferruginea Vahl, 

 are the principal character plants. 



The harbor of Port Antonio, Jamaica, is entered by two chan- 

 nels separated from each other by Navy Island and its outlying 

 coral reefs. The western channel is passable only to small sail- 

 ing craft, while the eastern channel between Navy Island and a 

 tongue of the mainland is navigable by the largest ocean-going 

 steamers. Navy Island is used to pasture cattle upon, and hence 

 it is grass-grown with only a few trees upon it and these grow 

 near the shore line. Laguncularia racemosa Gaertn., the almond
