plants, often attached to the roots of other plants. — Named from 
opoSnc, a leguminose or pea-like plant , and ayyar, to strangle ;

and apex. Osproleon. 
1. O. major L. ? ( greater -B.); stem simple, sepals 2-nerved

corolla campanulate ventricose at the base in front curved on 
the back, lips wavy scarcely denticulate, upper one concave

not unfrequent in England. If.. 5 — 7. — Stem 1 — ft. high, leafless. 
Whole plant dingy purplish-brown, pubescent. Stetn swelling at the 
base and very scaly ; scales more distant upwards and becoming

2. O. caryophylldcea Sm. ( Clove-scented B.) ; stem simple, 
sepals many-nerved lanceolate equally bifid shorter than the 
tube of the corolla touching each other or combined in front, 
corolla campanulate curved on the back, limb spreading un- 
equally toothed, upper lip broad 2-lobed, lower 3-lobed, the 
segments erect obtuse nearly equal wavy, stamens inserted 
above the base of the corolla, hairy below, their upper part

On the roots of Galium Mollugo, in South Kent. If . 7. 
3. 0. rubra Sm. (red B.)-, stem simple, sepals 1 -nerved subu- 
late acuminate longer than the tube of the corolla undivided,

upper lip within glandular-pubescent, lips acutely toothed and 
crisped, upper one 2-lobed, lower 3-lobed the middle segment 
rather longer than the lateral ones, stamens inserted near to 
the base of the corolla slightly hairy below, their upper part 
and the upper part of the style glandular-hairy, stigma pale red 
the lobes close. E. B. t. 1786. 
Frequent upon basalt and trap rocks in the Hebrides and adjacent 
shores of the mainland, parasitical upon Thymus Serpyllum. Near 
Kirkaldy. Cave-hill, near Belfast, Ireland. Cornwall. If. 7, 8. 
— We have no doubt of this and O. Epithymum DC. being the same ; 
but they differ in character as much as some of the other species.
