 longifolium Nees is given for Ceylon, but no specimen cited. 

 Thwaites 61, referred to E. zeylanicum by Hooker in Trimen, 

 Flora Ceylon, V., 3, is described as anew species, E. subglaucum 

 Ruhl. Thwaites' name E. atratum var. major is restored for 

 E. caulescens Hk. f. and Th. Gardner's No. 972 is given 

 for E. atratum instead of 932. Thwaites 796 is referred to 

 E. trilobum Buch.-Ham. (Central Province, also Walker); 

 it was referred to E. collinum by Hooker. E. nilagirense Steud.

 PI. Zeyl., 1 (1864), 341 = E. atratum Thw. pr. p., ibidem non 

 Koern. -= E. zaylanicum Hook. f.,Trm. Fl. Ceylon, V. (1900), 

 3, non Koern. ; Nuwara Eliya (Gardner) ; Ramboda, Central 

 Province (Derselbe, C. P. 789). C. P. 789 is Thwaites, not 

 Gardner. On the other hand, E. ceylanicum Koern. is given 

 for Ceylon, Nuwara Eliya, Gardner, without citation of any 

 specimen. E. intermedium Koern. is also cited for Ceylon 

 (Walker, &c.) without mention of specimen. E. Thwaitesii 

 Koern. and E. Neesianum Koern. are maintained distinct, 

 to the former being allotted " Ambagamuwa, Kitulgala 

 (Thwaites)," and to the latter Gardner No. 936 in Herb. Berol. 

 from Ramboda. E. capillus-naiadis Hook, f . is united to E. 

 setaceum L. E. collinum Hook, f . is retained in the Ceylon list, 

 but no specimen is cited ; the localities Ramboda, Amba- 

 gamuwa, are quoted from Trimen and attributed to Gardner, 

 but the C. P. specimen cited in Trimen is transferred to E. 

 trilobum. 



As a result of this revision, one Ceylon species E. capillus- 

 naiadis disappears, another, E. caulescens, is reduced to a 

 variety, and seven names, one a new species, are adtled. 

 According to Ruhland, the number of species of Eriocaulon 

 known from Ceylon is twenty-three.
