108 COLLECTED DESCRIPTIONS OE CUSCUTA. 
From Watson’s Contributions to American Botany, XI. (Proc. Amer. Acad. Arts and Sci., Yol. XVIII. Aug. 1883.) 
✓ C. Potosina, Schaffner mss.: stems capillary; the flowers minute (scarcely a line long), short-pedicelled [124] 
in small, rather loose clusters; calyx-lobes triangular, acute, scarcely equalling the deeply campanulate corolla- 
tube, which is rather longer than its erect, ovate, acute, somewhat indexed and at last connivent lobes ; stamens short, 
the subglobose anthers nearly as long as the filaments ; scales broad, deeply fringed, slightly exceeding the tube; capil¬ 
lary styles nearly as long as the depressed ovary; capsule covered by the marcescent corolla,, extremely thin, easily 
tearing off from its base, but not circumscissile, 1-seeded. — One. of the smallest-flowered species, closely allied to 
C. arvensis, from which the very fragile, 1-seeded capsule, covered by the hood-like corolla, principally distinguishes 
it. —Near San Luis Potosi (779 Schaffner); growing on some labiate, probably a Scutellaria. 
. C. MiTRiEFORMis, Engelnj.; stems thick; flowers short-pedicelled, crowded in large glomerules; calyx-lobes 
orbicular, unequal, the outer cafinjate, fully as long as the short-campanulate corolla-tube ; lobes of the corolla as 
long as the tube, broadly oval, founded, at last spreading or reflexed; subulate filaments as long as the linear-oblong 
anthers; scales very broad, deeply fringed, exsert, incurved; ovary with very short subulate styles; capsule large, 
exsert, 2-horned with the broad-spreading conical styles, regularly circumscissile. — Between San Luis Potosi and 
Tampico, in May ; Dr. E. Palmer. Flowers 3 lines and capsule 4 lines long ; clusters ini fruit 10 to 12 lines thick. 
Nearly allied to G. Xalapensis, but distinguished by its much larger flowers and fruit, and by its short, thick, almost 
cSnical styles.
