There are at Calcutta both flowering and fruiting examples of Teysmann 

 and Binnendyk's original species cultivated in the Buitenzorg garden ; these are 

 identical in every detail with this, common Sumatra and Malay Peninsula plant. 

 The pods much resemble those of M. atropurpurea, to which it comes nearest and 

 with which it has been identified by Mr. Baker. But, besides the double edge to 

 the plaits on the pods, whence the name, the Malayan differs from the Indian 

 species in having larger leaflets, shorter inflorescences, a calyx with an almost 

 truncate mouth and a collar of scaly bracts at the neck of the peduncle similar to 

 but smaller than those that occur at the base of the peduncle in M. bracteata of the 

 subgenus Stizolobium.
