Momordica zeylanica Mill. Diet. ed. 8: no. 3. 1768. Momordica, charantia ahbre- 

 riata Ser. in DC!. Prodr. 3:311. 1828. 

 A low-climbing plant, at least in cultivation; stem angled, puberulent; leaves 

 deeply 3-lobed, crenate; the lateral lobes again lobed; the base with broad open 

 sinus: blade somewhat puberulent ; flowers solitary ; peduncles with minute bracts 

 (a line or two long). 



Collected by Dr. Edward Palmer near Acapulco, Mexico, March, 1895 (No. 555) ; 

 also by Dr. Palmer at Cnliacan, August 27 to September 15, 18111 (No. 1522). 



Tliis plant is the same as Wright's No. 1206 from Mazatlan, Mexico, which is re- 

 ferred as M. charantia abbreviata by Dr. B. L. Robinson. 



The plant appears to me to he quite distinct from Momordica charantia, from which 

 it differs in the shape and much smaller size of the fruit, and in the smaller leaves 

 and bracts as also in the seeds. 



This form has a wide range, being reported from many places in the Old Worbl. 

 The only stations known in Mexico are the three named above.
