154 MISSOURI BOTANICAL GARDEN. 
sometimes entire, 6-9 cm. long, attenuate to a long petiole; 
calyx tube 8-9 cm. long, the lobes purple spotted, tips free 
and slender ; flowers 4-5 cm. in diameter; capsules oblong, 
about 3 cm. long, wings less than 1 cm. wide, short pedicelled ; 
seeds crested but scarcely tuberculate. — Specimens exam- 
ined: Waugh, Marena, Oklahoma, 1893, No. 183; Hitch- 
cock, Barber Co., Kan., 1895, No. 165a.—Plate 47. f. 1-3. 
Differs from M. Missouriense (Sims) Spach, in the ab- 
sence of all pubescence, the smaller flowers and fruit, the 
latter oblong and more tapering at the apex, and the thick - 
more dentate leaves with a thick marginal line. 
MercapTerium Fremonti (S. Wats.) Britton. 
Watson describes the seed as ‘* not crested nor tuber- 
culate.’’ In specimens from Kansas (Hitchcock, no. 165) 
the seeds are prominently crested and also somewhat tuber- 
culate.— Plate 47. f. 4. 
Mecaprerium MissouriensE (Sims) Spach. 
There seems to be a marked difference in the seeds of 
different forms of this species, but I have not had oppor- 
tunity to examine enough material to see whether the char- 
acters remain constant for the different forms or not. 
The seeds of the narrow-leafed Texan forms (var. A, 
Gray, Boston Jour. Nat. Hist. 6: 188) are light colored 
and have a crest sometimes 2 mm. broad with dentate or 
entire margin and extending almost the entire length of the 
seed. The seeds of the form common further north are 
smaller, darker colored and have a laciniate or lobed crest 
extending about half the length of the seed.— Plate 47.

Linaropsis CaROLINENSE Coulter and Rose. 
In the Joor herbarium is a specimen of this species 
recently described from plants collected on the Atlantic 
coast. The plant bears the following label in Dr. Joor’s 
handwriting: ‘‘Crantzia, n. sp.? Peduncles less than } 
length oflvs. Lvs. flat, with distinct lamina. Fs. pinkish.
