conspicuous. — Shrub 6-8 ft. high, Monte Cachirulo, Dept. 

 Yzabal, alt. 900 ft., Apr. 1890, J. D. S. (Ex PL cit. 1644). 



Triuris brevistylis. — About 3 in. high, aphyllous: inflor- 

 escence uniparous, twice furcate, peduncles \—\ in. long, 

 semi-amplexicaul bracts with rounded lobes at base: perianth- 

 segments with twice longer appendages -3-4 lines long: styles 

 pubescent, sub-terminal, capillary, deflexed, shorter than ob- 

 tuse carpels of ovary; stigma oblique; fruit obovate, puberu- 

 lous. — T. diapJiana Miers, one-third as large, with cauline 

 leaves, sheathing entire bracts, less developed inflorescence,
