flowers formed several complete whorls near the top, of 7 or 8 flowers in each 

 whorl. 



3. 0. HedercB, Duby. Ivy Broom-rape. " Stem simple, sepals 

 1 -nerved ovate below suddenly contracted into 1 — 2 subulate 

 points nearly as long as or longer than the tube of the corolla, 

 corolla tubular curved, limb denticulate wavy, upper lip 2-lobed 

 its sides straight, lower of 3 roundish nearly equal lobes, middle 

 lobe rather the longest, stamens inserted above the base of the 

 corolla glabrous with a few scattered hairs on the lower half, style 

 glabrous downy or with a few hairs on the upper part, lobes of 

 the stigma (yellow) cohering to near the middle." — Br. Fl. p. 286.

At the roots of Ivy, in moist shady woods, on damp rocks, walls and hanks, 

 chiefly at the back of the island, hut prohahly only a variety of the last species. 

 Fl. July— October. ? 



E.Med. — At East-end. Common at Bonchurch, and on banks at Venlnor. 

 Abundant about Steephill, in Pelham woods, and in general throughout the 

 Undercliff. 



Stem 1 or frequently 2, 3, or more from the same swollen base, beneath which 

 are a few short, stout, yellow fibres, attaching the plant to some creeping filament 

 of the root of Ivy at a few points only, the rest striking into the earth in the usual 

 way ; erect, from a few inches to nearly 2 feet in height, simple, and mostly slen- 

 derer than in O. minor, bluntly angular, purple and very downy with gland-tipped 

 hairs. Scales most numerous about the base of the stem, pale, fleshy, ovate and 

 imbricated, those higher up lanceolate, scattered, withering to a dark brown colour. 

 Flowers in an elongating spike, usually more distant and less numerous than in 

 O. minor, occasionally very few and remote, sessile, alternate, pale cream-coloured, 

 afterwards purplish, finally brown, the corolla strongly veined with purple. 

 Brads solitary, ovato-lanceolate, purple, with slender often deflexed points as long 

 as or longer thau the corolla. Sepals ovate, fringed, each terminating above in 

 one or two long subulate points, the lower, when two are present, shorter than its 

 fellow, and continued downwards into a less prominent nerve ; where there is but 

 one point the rudiment of a second usually exists as a more or less distinct tooth 

 or angle, which is rarely quite obsolete ; the upper or longer point of the sepal is 

 about equal to the tube, and is continued to the base of the calyx as a strong rib 

 or nerve keeled anteriorly. Corolla cylindrical or tubular, scarcely at all enlarged 

 or dilated upwards, arched or curved, very hairy, and having mostly 6 strong pur- 

 plish ribs with a few obscurer intermediate ones ; of these ribs the three most 

 conspicuous occupy the under side of the tube, one running up into the centre of 

 each division of the trifid lower lip ; upper lip of the corolla slightly 2-lobed, the 

 lobes deflexed, crisped, notched or toothed on the margin ; under lip in 3 very 

 distinct segments, of which the centre one is the largest and longest, fan wedge- 

 shaped, the 2 lateral more or less lobed, rounded, all variously plaited, cut or 

 notched on their edges. Stamens in all the very numerous specimens before me 

 inserted much higher on the tube than described by Mr. Babington, quite 

 as much so indeed above the base as in the equally numerous examples of O. 

 minor also before me for comparison (the point of insertion of these organs is per- 

 haps variable, as in some PrimulacesB and Boraginaceje) ; filaments compressed, 

 dilated at the base as in O. minor, but far less hairy beneath at the inner side 

 than in that;* anthers with very prominent awns. Style incurved at the apex, 

 minutely downy in the upper part or very nearly quite glabrous ; stigma 2-lobed, 



* Posterior filaments, according to Lloyd (' Flore de la Loire Inferieure,) 

 widely separated at the base ; in 0. minor the posterior filaments are approximate 

 and parallel, as the same author remarks 1. o. c. pp. 191, 192.
