COMPILATIONS 
Under this head it is our intention to publish each month, 
or as often as space may permit, either entire reprints or synop- 
ses-of. articles which appear in journals not accessible to those 
who have limited library facilities. Other botanists are cord- 
ially invited to contribute, both by sending material for this de- 
partment, or by pointing out where it may be obtained.

The above description is copied from Willdenow, and both 
Britton in the Illustrated Flora, and Piper in the Flora of Wash- 
ington, cite it as the original one. If the name in Ind. Hort. 
Cantab. is without description, or if a description is given there 
‘and differs from that of Willdenow, I should consider it a great 
favor to have the facts communicated to me. According to the 
description, the plant we have conimonly called Claytonza per- 
fotiata, then Montia perfoliata, and now Limunia perfoliata, is 
probably some other species.
