This has very much the general habit of Abronia arenaria, but appears to 
be quite destitute of pubescence, although, if we may judge from the 
sand adhering to the stems, it is equally glutinous with that species. 
The leaves afford the most essential specific character; for here they 
are ovate or oblong, not by any means cordate, somewhat acute both 
at the base and the extremity. The flowers, too, besides being some- 
what larger, are of a fine rose colour, with a white eye in the centre. 
The seedvessels, according to Lamarcx’s figure, are longer and nar- 
rower. 
This seems sufficiently’ to accord with the figure and de- 
scription of Lamarcx’s Abronia umbellata, which is probably 
a copy of L’Hrnririer’s plate. Sir James Smitru considers 
that this plant was perhaps the only fruit of La PryRousE’s 
unfortunate expedition: the seeds, as is related under A. are- 
naria, having been sent to Kurope by M. CoLicNon, gardener
