* Dicerandra odoratissima sp. nov. 



Annual. Base of stem enlarged, and, like the larger roots, 

 covered with sinuous longitudinal ridges : stem 2-4 dm. tall, 

 fastigiately branched from the base : leaves opposite, linear, 2-1 

 cm. long, with a few smaller ones fascicled in their axils : flow- 

 ers odorous, very short-pedicelled, in 3-5 -flowered sessile axil- 

 lary cymes, becoming crowded toward the summits of the 

 branches, the uppermost opening first : calyx ascending or erect, 

 about 8 mm. long, 13-nerved, somewhat bilabiate, the upper lip 

 rounded and entire or nearly so, the lower of two slender incurved 

 teeth, exceeding the upper ; limb of the calyx white, the re- 

 mainder green : corolla about twice the length of the calyx, 

 white, sprinkled with numerous minute purple spots ; tube straight, 

 included in the calyx ; upper lip arched, the lower spreading or 

 deflexed, and 3-lobed: stamens 4, the anterior pair longest, but 

 not exceeding the corolla ; anthers purple, 2-celled, with short 

 purple horns : style bifid, slightly exceeding the corolla. 



A beautifully distinct species, differing from its two congeners 

 (D. linearifolia (Ell.) Benth. and D. densiflora Benth.) more than 

 they do from each other, so much so that the generic characters 

 will have to be somewhat modified. Among the characters by 

 which it differs from both are the nearly sessile flowers, white- 

 limbed calyx, white corolla, and included stamens. The odor of 

 the flowers of D. odoratissima is peculiar, suggesting that of the 

 insect Cimex lecttdarins, but not unpleasant. I do not remember 



lected that species a few years ago. 



'ifolia 



D. odoratissima differs further from D. linearifolia 



D. linearifolia 



and perhaps in D. densiflora also), and from D. densiflora in its 

 linear leaves. Some specimens of Z>. densiflora which I have ex- 

 amined have an enlarged stem-base approaching in size that of 

 D. odoratissima, but I have not observed this character in D. 



v 'ifolia. 



Dicerandra odoratissima ^rows in abundance in dry
