Close as this species stands to C flexmsas, it has so peculiar an aspect,
that we prefer to keep them separate, basing the distinction on the short
straight leaves of C. paradoxus, with the lamina distinct to the apex. The
original specimens are scarcely an inch in height, and amongst the stems
are some with terminal rosettes of short ovate leaves more laxly areolate,
these are probably abortive males ; Whitehead’s specimens are in. high,
and Wesley’s nearly as tall. It is probable that it may eventually have to
sink to a Var. of C. fiexuosus.

serrated hispid subula.

A form parallel to the variety of C. Shawii. The comal leaves of the
ordinary state are frequently more or less secund, and slender flagelliform
ramuli are also common. When the fragile hair points are lost, it is best to
examine the young apical leaves, on which they are usually retained, otherwise
there might be a difficulty in the determination of the species.
