Tinclude (Hook. f. Fl. Brit. Ind. v. p. 607) under C. Rumphii the 
Asiatic forms from the Andamans eastward. I conjecture there- 
fore that Hancock’s Hainan plant (C. circinalis teste Maximowicz 
in litt.), and that which according to Hance (teste Bretschneider) 
“ grows wild in Formosa,” belong to it.

Closely allied to C. pectinata, Griff. (Kurz, l. c. p. 503; Dyer, 
l. c. p. 657), and perhaps only a southern geographical form; 
it has usually shorter stems often swollen at the base. Plants 
have been introduced in quantity from the island of Pulo Condor 
into European horticulture and sold under various names, amongst 
others of C. Boddami which (Dyer, l. c. p. 656) is a reduced form 
of C. circinalis from S. India. I suspect C. Bellefonti, Lind. & Rod. 
(ZU. Hort. xxxiii. (1886) t. 586), from Tonkin to be C. siamensis.

Carruthers states (7. c.) “ that the specimens were collected in 
the island of Formosa by Mr. Swinhoe, and sent to Dr. Hance 
in the autumn of 1867 . .. . on which the species is founded." 
In the Kew Herbarium there is a single carpophyll of .this 
species accompanied by a letter from Swinhoe. written from 
Amoy, Aug. 21, 1867, in which he says :—“ The Chinese call it 
the Hai-te-koe or Sea-iron fow] (sea-iron is the name given to
