In spite of the apparent dift'erence between the fruits of this and the next 

 species, the two are so closely allied that 1 have been unable to find any constant 

 characters by which sterile or flowering specimens can be distinguished, and 

 accordingly a number of flowering specimens which doubtless belong in part to 

 the present species, are cited below, although probably they for the greater part 

 belong to the next, which is the more common and widely distril)uted one in 

 the Philippines. The specimens cited aI)ove are all with fruit. 



Two specimens in the herbarium of the Bureau of Science sliow some steps of 

 intergradation between P. echinatus and 7*. indiciis ; the first {For. Bur. 10)25 

 Curran, Camarines Piovince, Luzon), presents the pods with numerous, very 

 short spines, less than 1 mm long, on most of the pods, but witli other pods 

 with no traces of these short spines; the second (For. Bur. 7060 Klemnte, Cagayan 

 Province, Luzon) presents pods for most part entirely smooth. l)ut 3 or 4 of 

 the 15 on the specimen have each from two to five spines in all respects similar 

 to those of /*. echinatus. 



J'leroearpus klemmei is liere reduced to /'. echinatus, as I am convinced that 

 the type of the former is only a sjiecimeii of tlie latter s])ecies with very im- 

 mature pods. 



Flowering specimens, in jiart doubtless referal)le to tlie above species, but 

 ])robal)ly for the greater part belonging to the following one:
