Tricolor differs from acaulis, which appeared in the 
fasciculus of the last month, by a foliage, which is obso- 
letely villous on the upper side, not covered by a dense 
rough pile, and by a flower of a different colour; but more 
decidedly by the remarkable outer leaflets of the calyx, 
which are narrow linear subclavate recurvedly mucronate 
and of a frosted white colour; the innermost ones are also 
more pointed than in acaulis. 
The curious economy and sensitive property which we 
observed in the style and stigmas of awreola and aspera, and 
described in the 32d and 34th articles of this work, 
are likewise found in the three species since published, 
and will be so probably in many, if not all, others of 
the genus,
