3. D. benifobmis, Kurz in Pegu Eep. App. A. 49. and B. 45. 

 {Balbergia reniformis, Koxb. Fl. Incl.'III. 226 ; Wight Icon. t. 261 ; Hf. 

 Ind. Fl. II. 238 ; Balbergia jlexuosa, Gran, in Wall. Cat. 5875 ; Bth. in 

 Linn. Proe. IV. Suppl. 48). 



Hab. Frequent in the swamp-forests and around lakes and marshy 

 grounds, especially in the alluvial lands, all over Pegu and Martaban down 

 to Upper Tenasserim. — Fl. Febr. March ; Fr. Apr. — June. 



Curious on account of the joints being dimorphous on the same or 

 on different pods. They are either normally thick-coriaceous and as flat as 

 those of the following species, and have the seeds much compressed ; or 

 they are firmly fleshy and up to half inch thick, in which case the seeds are 

 larger and scarcely compressed. This latter state is not attributable to the 

 agency of insects, but seems to be normal development. The full-grown 

 foliage so much resembles that of Bep. inunclatus, Mart., that I should 

 experience some difficulty in distinguishing between the two species when 

 out of flower or fruit.

 My plant is Miquel's B. Zollingeriana, which Bentham connects 

 with the Philippine plant.
