NEW OR NOTEWORTHY PLANTS FROM COLOMBIA 
AND CENTRAL AMERICA—6.’ 
By Henry PITtier. 
INTRODUCTION. 
In this sixth contribution to the Colombian and Central American 
flora, further new species from recent collections made by myself 
and others are described and a few old types, hitherto imperfectly 
known, are redescribed. There is also proposed a new arrangement 
for a section of the genus Combretum.
