and paler" than in C. latijlora is very indefinite, for we have 

 nothing in literatnre which indicates the. size of, the flowers in 

 the type of that species. It was practically a nomen nudum 

 until the Synoptical Flora was issued, and the description there 

 does not mend matters much, for it is made to include several 

 forms, distinct enough in the field, and never growing near each 

 other so far as I have observed. Jones' plant is evidently dis- 

 tinct, even if it is not the same as ours, which may be charac- 

 terized as follows: 



Annual, varying in height from i to 2 dm., branched from 

 the base, the spread often equaling the height, somewhat woolly 

 below, and sometimes more or less glandular: leaves thin, mostly 

 basal, oblong, 4 cm. long or less, maximum width about i cm., 

 pinnatifid or variously sharply cut and lobed, the divisions acute 

 and spinescent, woolly but the green color not obscured, or some 

 plants nearly smooth; upper leaves when present small and bract 

 like, or some on the middle part of the stem with one or two 

 short lobes: pedicels slender, almost filiform, 2 cm. long or less, 

 glandular above: calyx narrowly campanulate, 3 mm. long, 2mm. 

 wide, glandular, green except the narrow scarious intercostal 

 spaces, the short, lanceolate lobes awn pointed: corollas about 

 15 mm. long, 10 or 12 mm. wide wdien fully expanded, the slen- 

 der tube proper i mm. across, 6 to 8 mm. long, purple, the fun- 

 nelform throat yellow at base, dark violet-purple above, merging 

 into the pale violet-purple of the lobes, which are broadly ob- 

 ovate, 5 mm. long and about as wide, the rounded apex tipped 

 with a short broad point: stamens a little exserted from the 

 throat, the anthers purplish or bluish: styles commonly almost 

 as long as the corollas, the slender linear stigmas 2 or 3 mm. 

 long, downcurved. 



This is distinct from any of the various forms cf G. latiflora 

 known to me, and if it should prove different from the type of 

 G. caua^ a name will be supplied later.
