BRAZILIAN REGIONS. 



41 



Trigonia (No. 1). A woody vine. 



? (No. 2). A tree. On the Organ Mountains. — In general, Polygalacece ■were 



not very prominent amid the vegetable growth. , 



Mollugo. On the sea-beach. (Compare Australia, Interior Oregon, and North California.) 



Paritium tiliaceum ? (compare No. 1 Metia and the Hawaiian Islands to Sooloo in the 

 East Indies). The flowers yellow. Submaritime ; growing in salt marshes, and in the 

 drier portions of the mangrove swamps. 



Pavonia (No. 3). 



Carolinea ? (No. 1). The leaves only, of a tree supposed by us to belong to this genus. 

 Helicteres (No. 1). 



Chorisia speciosa, St. Hil.; (No. 1). The trunk thickly clothed with large prickles. 

 Frequent in the environs of Rio Janeiro; but not seen in the " matto virgem" or pri- 

 meval forest, nor anywhere on the Organ Mountains. — Bonibacece, being usually large 

 trees, are perhaps not rare in Southern Brazil : young stocks were occasionally observed 

 that seemed to belong to this Tribe ; but we hardly met with any fallen flowers or fruit. 



Waltheria elliptica, (compare No. 1 Hawaiian and Feejee Islands, and Zanzibar). Fre- 

 quent, intermingled with the Sidas along road-sides and in open spaces : possibly 

 introduced. 



Luhea (No. 1). A forest-tree. On Mount Corcovado. 



Heisteria (No. 1). At Praya Grande, on the opposite side of the bay; rather frequent. 



Ximenia Americana ? (No. 2). A small tree. Submaritime ; growing along the bay- 

 shore, near the landing-place at Piedade. 



Hypericum (No. 16). Herbaceous and small; agreeing in habit with our Northern spe- 

 cies. Growing by the road-side, beyond the Organ Mountains. 



(No. 17) ; a second small herbaceous species, of similar habit. 



Vismia (No. 1). A small tree. Frequent. 



Clusia alba? (No. 1). A small tree, twelve to twenty feet high, with very stout leaves; 



the flowers white. Submaritime; growing abundantly along the sea-coast. 



(No. 2). On the Organ Mountains, and elsewhere. 



\ (No. 3). A small tree; the leaves small, and the flowers dull reddish-purple. 



In the Piedade Gap of the Organ Mountains, at the residence of Mr. March, "3100 



feet above the sea." 



Norantea (No. 1). A large shrub, twelve feet high. In drowned land along the Piedade 



road ; and also growing near the sea-shore, in front of the Lagoa de Peteninga. 

 Erythroxylon (No. 6). 



Stellaria media, (bis United States, &c.) Growing in the horse-path leading to the Pie- 

 dade Gap in the Organ Mountains; evidently introduced. 



Drymaria cordata, (No. 1 ; bis Luzon). Rather frequent ; but seemed discordant, hav- 

 ing much of the aspect of an introduced plant. 



Sida rhombifolia ? (No. 20). Abundant in waste ground, along road-sides, and in all 

 open spaces ; (possibly indigenous). 



(No. 21). The petals contorted. Growing intermingled with the preceding spe- 

 cies, and also abundant; (possibly indigenous). 



(No. 22); apparently a third species. Growing intermingled with the two pre- 

 ceding ; and (possibly indigenous).
