Fleurya Gaud. 



F. aestuans Gaud, in Freyc. Voy. Bot. 497 (1826); Rob. 

 (1), 132.— Abingdon Isl. : common, 800-1100 ft, (no. 1172). 

 Albemarle Isl. : Iguana Cove, abundant from the beach to 

 600 ft. (no. 1325) ; Tagus Cove, common in lava crevices in 

 shade, 300-2900 ft., (no. 1177); Villamil, abundant among 

 rocks, 300-1300 ft, (nos. 1174-1175). Charles Isl.: occa- 

 sional among rocks at 1550 ft. (no. 1326). Chatham Isl.: 

 Basso Point, occasional in shady places at 900 ft. (no. 1327). 

 Duncan Isl. : common on the sides of steep lava cliffs at 1000 

 ft, also common around 1250 ft., (no. 1328). Hood Isl.: 

 occasional in lava crevices, 400-600 ft., (no. 1329). Indefat- 

 igable Isl. : Academy Bay, occasional among rocks at 50 ft. 

 At this elevation the specimens are low and with many stinging 

 hairs on the stem. This same species also grows very abund- 

 antly around 600 ft., where it attains a height of 3-4 ft. and 

 has fewer stinging hairs on both the stems and leaves than 

 do the specimens taken from the lower elevations, (nos. 1130- 

 1331 ). James Isl. : James Bay, Snodgrass and Heller. Nar- 

 borough Isl. : south side, Snodgrass and Heller. This species 

 shows much variation both in size and in the arming of the 

 stem and leaves, but the differences are not sufficient to be of 

 formal value. Further distr. Mex., W. Ind., S. Am.
