Further notes on Cereus giganteus of Southeastern California
and a short account of another allied species in Sonora.
by Dr George Engelmann of St Louis, Missouri.

Specimens of flowers and fruit, together with interesting notes and drawings
communicated by Mr George Thurber, and specimens of ribs of the plant with
spines
presented by Dr Parry enable me to perfect the history of this giant Cactus.*
Mr Thurber travelled through the Gila country and Sonora as one with Mr
Commissioner
Bartlett's party in the summer of 1851, and is believed to be the only
scientific gentleman, who has seen the plant in question in flower.
