Closely allied to Fentilago, from which it differs by its dehiscent capsule, and named in honour of 
Colonel Smythe, R.A. At present we know only one species, S. Pacifica, but it is possible that Ventilago (7) 
Vitiensis, of which the fruit is unknown, may prove to be a second species.

Catha crenata, A. Gray, Bot. Wilkes, p. 288, must rank as Gymnosporia crenata, Seemann. Forster and 
Barclay collected it in the Marquesas; but it has not been found in the Society Islands. A third Polyne- 
sian species of Gymnosporia was found in and off New Caledonia (Vieillard! n. 223; Milne! M‘Gillivray!).
