THE BROOM-RAPE FAMILY 
83 
a variety, differing in its pale colour, and in the purple stigma-lobes just touching one another. 
The whole plant is whitish ; it is, in fact, the palest of our native Broom-rapes. ( Under Orobanche 
minor , var. Picridis. Benth. and Hook) 
Very rare, local. A parasite on the Hawkweed Ox-tongue (Picris hieracioides), found in the 
Isle of Wight, Kent, Cambridgeshire, and Pembrokeshire. July. Perennial. 
7. Ivy Broom-rape. (Oroban'che Hed'erse. Duby.)— Another similar species which 
chiefly differs from the Lesser Broom-rape in having the central lobe of the lower lip of the corolla 
larger than the side ones, in the lobes of the stigma being yellow and touching one another, and 
in the stem and bracts being purple, and the cream-coloured flowers being tinged with purple. 
( Under Orobanche minor , var. Hederce. Benth. and Hook) 
Rare, local. A parasite on Ivy (Hedera), in the south-western counties of England, in the west 
up to Carnarvon, and in Ireland. Tune — July. Perennial. 
8. Purple Broom-rape. (Oroban'che amethys'tea. Thuill.)— . Another species often 
regarded as a variety of the Lesser Broom-rape, which differs from it in the flowers being more 
strongly tinged with purple, in the corolla-tube being curved directly from the base and then being 
straight, and in the central lobe of the lower lip being much larger than the side ones. ( Under 
Orobanche minor, var. amethystea. Syme, and Benth. and Hook) 
Very rare. A parasite on the roots of the Seaside Carrot (Daucus gummifer), in Cornwall, 
Devonshire, and Kent, and on Sea-Holly (Eryngium maritimum) in Jersey and Guernsey. June. 
Annual. 
9. Blue Broom-rape. (Oroban'che purpurea. Jacquin.) — Flowers |-i inch long, pale 
blue with purple veins, in a rather dense spike, with 3 bracts below each flower. Calyx of 5 sepals, 
narrow and pointed, only united at the base ; corolla narrowing and curving at the top, the two 
lips with pointed lobes, all being more equal than in the preceding species although still divided 
into 2 lips ; the stamens smooth, inserted just below the middle of the corolla-tube ; the stigma 
scarcely lobed, white ; and the capsule opening by 2 valves from the top. [As described in the 
genus Broom-rape (Orobanche).] The stem is unbranched, from 6 inches to 1 foot high, slender, 
and tough, with narrow lance-shaped scales ; the whole plant is downy with gland-tipped hairs. 
{Orobanche carulea. Vill) 
Rare. A parasite on the roots of the Common Yarrow (Achillea Millefolium) in meadows and on 
grassy walls near the sea, in some of the southern and eastern counties of England, and in the 
Channel Isles. June- — July. Perennial. 
10. *Sand Broom-rape. (Oroban'che arenaria. Borkh.)— Not a native. A very 
similar species to the last, with paler blue flowers, i-i^ inches long, the corolla less curved and 
more gaping, the anthers hairy, the stigma yellow (?), and the whole plant larger, 12-18 inches 
high, white or tinged with blue. ( Under ccerulea. Benth. and Hook) 
A native of the Continent. A parasite on the roots of the Field Wormwood (Artemisia campestris) 
which has been found in Alderney. June — July. Perennial. 
1 1 . *Branched Broom-rape. (Oroban'che ramdsa. Linn.)— Not a native. A species 
somewhat similar to the Blue Broom-rape (Orobanche purpurea), but with much smaller, rather 
more yellowish flowers tinged with blue, the calyx of only 4 broader sepals which are united 
halfway up into a tube, the corolla-lobes blunt ; and the yellowish stem branched, and seldom 
more than 6 inches high. 
A native of southern Europe. A parasite on Hemp, Lucerne, and other plants, which has 
been found in some of the southern and eastern counties of England. August — September. 
Annual.
