T h e wild recent fpecimens of this very rare plant, from
which our drawing was taken, were gathered July 27, I79<?,
near Middleton in Teefdale, Durham, by the Rev. Mr. Har-
riman, and Mr. Oliver furgeon, of Middleton, and fent us by our
liberal correfpondent Mr. E. Robfon. Ray and Hudfon found
this Bartfia near Orton in Weftmorland, and Mr. Dickfon firft
obferved it in Scotland. It prefers a moift ftony foil, on the
borders of alpine rills, or little boggy fpots in the interftices of
rocky precipices, flowering after the middle of fummer, and
foon ripening its feed.
The root is perennial and creeping. Stems from 4 to 8
inches high, ereft, Ample, fquare, clothed from top to bottom
with feveral pair of oppofite feflile leaves, which are, ovate or
heart-lhaped, acute, ftrongly ferrated and veined, fmooth above,
hairy beneath; the lowermoft are very fmall; the uppermoft
coloured with purple, and out of the bofoms of thefe the flowers
arife folitary, on very fhort flower-ftalks, forming a terminal
leafy fpike. The calyx is vifcid and hairy, in 4 nearly
equal fegments, tipped with purple. Corolla of a violet purple,
thrice as long as the calyx, comprefled, clothed with
glandular vifcid hairs; the lower lip reflexed. Antheras prominent,
very hairy. Style projefting beyond the (lamina,
with a blunt ftigma. Capfule ovate, downy, of two valves,
with a tranfverfe partition arifing from each. Seeds numerous,
angular, with membranous ftriated angles, more akin
to- thofe of Rhinanthus than to thofe of Melampyrum^ with
which laft genus the flower of Bartfia has great affinity.
The whole herb turns very black in drying, efpecially when
gathered young.
