Kalanchoe Brasiliensis, St. Hil.; (No. 1). Submaritime; frequent on rocks along the 



bay -shore at Praya Grande ; yet seeming discordant, hardly having the aspect of an 



indigenous plant. 



Opuntia (No. 4). A large species. Growing on rocks, and rocky bluifs facing the sea. 

 (No. 5) ; "a second species," Brackenridge. 



"Melocactus" (No. 1). Submaritime. Buried to the crown of flowers, in the sands near 



the Lagoa de Peteninga ; rare, once only met with. 

 Cereus (No. 1). Columnar. Frequent along the sea-shore. 



(No. 2). Columnar. Growing on rocks along the sea-shore, at the Lagoa de 



Peteninga and elsewhere. 

 (No. 3). Scandent; the stems quadrangular. Frequent along the sea-coast. In 



some instances fairly epidendric, having made a lodgement in tree-tops. 



(No. 4) ; "a fourth species. Scandent; the stem triangular," Brackenridge. 



(No. 5) ; a fifth species. 



Epiphyllum (No. 1). Met with in the neighborhood of the Organ Mountains; epiden- 

 dric on the roots and trunks of trees in the forest. 



(No. 2) ; "a second species " observed by Mr. Brackenridge. 



Rhipsalis (No. 1). Epidendric, pendent from the trunks of trees ; frequent. 

 (No. 2) ; a second species. 



(No. 3). At the summit of one of the peaks of the Organ Mountains. 



(No. 4). On rocks, near the Lagoa de Freitas. 



(No. 5) ; a fifth species. 



Belangera speciosa, St. Hil.; (No. 1). A tree. Rather frequent at Tijuca, and elsewhere 

 in the environs of Rio Janeiro; observed also, among the Organ Mountains. 



Psidium guayava, (No. 4 ; bis Taheiti, Hawaiian Islands, Luzon, Hindostan, and Zanzi- 

 bar.) Cultivated; and besides, abundantly naturalized in somewhat open situations, 

 as far as we journeyed beyond the Organ Mountains; perhaps not indigenous in this 

 part of Tropical America. 



(No. 5). A small tree; (the fruit unripe, perhaps not esculent). Planted in a 



garden at Tijuca. I had previously seen specimens collected by the late Dr. Wm. 

 Baldwin, and attributed, perhaps through some displacement, to Florida. 



Carica papaya, (No. 1 ; bis Metia and the Hawaiian Islands to the East Indies, Hindos- 

 tan, and Zanzibar.) Seen only under cultivation; it being "considered necessary to 

 plant in proximity" the kind with paniculate flowers.
