Tree (?) ; leaves ovate-oblong or elliptic, 10 to 20 cm. long, 6 to 10 cm. 

 wide, shortly obtnse-acuminate, entire, 5 or 7-nervecl, glabrous ; flowers usu- 

 ally 6-parted, in open terminal panicles 10 to 30 cm. long, puberulent ; liral>

Triolena radicans T. S. Brandeg. Univ. Calif. Publ. Bot. 4: 379. 1913. 



Veracruz and Chiapas. 



Plants lierbaceous, ascending, the stems simple; leaves long-petiolate, oblong 

 or oblong-ovate, 5.5 to 13 cm. long, acute, undulate-dentate, 5 or 7-nerved, 

 emarginate and unequal at base, setose above, hirtellous beneath along the 

 nerves: flowers 5-parted, in long-pedunculate scorpioid racemes; calyx turbi- 

 nate, furfuraceous-puberulent, the lobes short; petals pink, 5 to 6 mm. long; 

 capsule 3-valvate, included in the finally 3-winged calyx. 



It is possible that T. radicans is a distinct species, but the material at hand 

 affords no basis for such a belief.

 narrow, acute ; stamens subequal ; fruit a small berry.

 to 20 cm. long, long-acuminate, 5 or 7-nerved, subentire. sparsely setulose above, 

 hirtellous beneath ; panicles narrow, becoming lateral ; calyx setulose, the tube
