 foliola 2 caeteris longiora, paniculam superantia. Spicules \ unc. longa?, ovato-oblonga;, compresses, biflorae, infe- 

 riores lonoius et graciliter pedicellatae. Squama sub 6, atro-castanese, concavse, ovatae, acuta; v. sub-acuminatae, 

 nitidaa, inferiores vacuae. Stamina 3. Seta hypogyna 4-6, rigidse, scabridee. Nux breviter stipitata, late ellipticn, 

 angolis costatis, stylo elongato stigmatibus 3 capillaribus exsertis tenninato. 



One of these two species of Chatospora may be considered the Antarctic representative of the Sclicenus nigricans 

 of Europe. Neither of them appears to inhabit a high south latitude, though the C. Antarctica, ascending to an 

 elevation of 2,000 feet in South Chih, might have been expected to grow at the level of the sea in Fuegia.

The Carpha schomoides of the hills of Fuegia, and the C. alpina, Br., of the loftier mountains of Tasmania, are 

 two closely-albed representative species, both apparently very rare and local plants. C. alpina is replaced further 

 north, in Australia, by the C. deusta, Br., a native of the colony of Port Jackson, but hitherto no South American 

 species except the one here described has been noticed. These three form together a very distinct group, as 

 Mr. Brown has indicated (Prodi-, p. 230).
