Zygopetalum africanum. Hooker in Bot. Mag. t. 3812. 
A native of Guatemala, whence it was sent to Mr. Bate- 
man by his correspondent Mr. Skinner. Having however 
been also communicated at the same time to Lord Rolle and 
Sir Charles Lemon, it first flowered at Bicton, whence the 
beautiful specimen figured in Mr. Bateman's work, t. 6, was 
sent. That now represented was given me by Mr. Bateman 
in April, 1837. 
It has already been observed, in the Miscellaneous notices 
of this work, No. 139, for the present year, that the Zygo- 
petalum africanum, sent to Sir W. Hooker from Mr. F orbes 
of Woburn, as a Sierra Leone plant, collected by Mr. Whit- 
field, is no other than a pale variety of this species. Upon 
turning to Mr. Bateman's work I see that he speaks of a 
variety * with a pure white lip, and pale green sepals and 
petals faintly blotched with a darker colour :” and it is pro- 
bable that the Woburn plant belongs to that very variety. 
Most assuredly it never came from Sierra Leone. Those 
who have charge of imported plants ought to be very careful
