Pods few, usually one or two in each raceme, reflexed, narrowly oblong,

lJill Ramos, August, 1906.

at all glandular beneath, and absence of stipules.

Indigofera zollingeriana Miq-, has not only page priority over I. teysmanni, 
but the part of the volume containing the description of it antedates the part 
containing the description of I. teysmanni by about three years. This is much 
the largest of our Philippine species, sometimes reaching a height of about 8 m. 
It extends from sealevel to an altitude of at least 1000 m. It differs from all 
the other Philippine species in its short calyx-teeth, and in its pods being 
pointed forward in the direction of the main axis of the raceme, or more or less 
spreading, but not reflexed.
