In article twenty-seven of these Leaflets were enumera- 
ted the Gesneraceae from the Horn of Negros—listing seventeen 
species of which fifty per cent were described at that time as 
new. It was indicated that most of our Philippine species 
prove new to botanical science, especially of certain genera. 
In the mount Apo region which has the richest and most 
interesting flora of any other equal mountainous area in these 
islands, the writer collected twenty species of this family, 
fourteen of which are here proposed as novelties. 
Typical Rhynchoglossum  klugioides Clarke was only once 
seen, and grew in masses in rich moist humus covered soil 
along the Colon creek of dense mossy forests. Jsanthera dis- 
color Maxim. has often been met between 2000 and 3000 feet 
altitude. Paraboea ridleyi Elm. is here described for the first 
time, and formed dense clusters on the upper edge of a 
bluff along the Sibulan river at about 1000 feet altitude, 
where the cool wind of the river current was constantly felt. 
Stauranthera philippinense Elm. is likewise here reported and de- 
scribed for the first time; only a few plants were noticed here 
and there in water soaked fine gravelly or sandy soil along 
streamlets in darkly shaded ravines. Of T'richosporum philip- 
pinensis (Clk.) O.K. only one plant was found in the rainy 
forests at 3750 feet. The exquisite Trichosporum cardinale Copel.
