Caliphruria teñera is the smallest-flowered Colombian Colombian
representative of Caliphruria. It is readily
distinguished by its hysteranthous leaves and the
long teeth of the androecium which greatly exceed
the short free filament (Fig. 104A). Unfortunately,
C. teñera has not been re-collected since 1853.
The hysteranthous leaves of this species suggest
adaptation to drier habitats than usually characteristic
of the genus. Pockets of xeric vegetation
do occur in the vicinity of the type locality (Cuatrecasas,
1958).
