74 The Flora of Wiltshire. 



species. When first developed it is of a pale yellow, but very- 

 soon assuming in every part, a dingy purplish brown colour. One 

 to one foot and a half high, leafless. Flowers in a long spike. 

 Stigma of ttoo distant yellow lobes. Anthers white when dry. 



2. 0. minor, (Sutt.) lesser Broom-rape. Engl. Bot. t. 422. 

 Locality. Parasitical chiefly on Trifolium pratense, the crops of 



which it often completely over-runs. A. Fl. June, July. Area, 

 1. 2. 3. 4. 5. 



In all the Districts, and not uncommon throughout Wilts. A 

 very variable plant in size and colour, often not more than 4 or 5 

 inches, at other times more than a foot and a half in height ; 

 usually of a dingy purplish brown or bluish colour. Corolla 

 tinged with violet in its upper part, downy, with several strong 

 purple ribs. Stamens more or less hairy in their lower part. 

 Anthers yellow when dry. Stigma hilohed, lobes purple. It varies 

 according to station and the plant it afiects. I have seen some of 

 the clover-fields in the county completely infested with this 

 species. 



3. 0. Med'erce, (Duby) Ivy Broom-rape. 0. barbata Engl. 

 Bot. Siippl. t. 2859, not Poir. 



Locality. Parasitical upon Ivy, in moist shady woods, and on 

 walls and banks. P. Fl. June, July. Area, * * 3. * * 

 South Division. 



3. South-west District, On Ivy in the Rectory garden at Bishops- 

 trowe. " Cop-heap," Mr. R. C. Griffith. 



The only localities at present recorded in the county for this 

 species, which may possibly be only a variety of the last (0. minor). 

 Stems purplish, about one foot high. This is best distinguished 

 from the last by its yellow stigma, cleft only two thirds down 

 instead of to the base. Anthers fuscous, rather paler when dry. 



O. elatior, (Sutt.) Engl. Bot. t. 568. 0. major (L.) Fries, has 

 been reported to have been found in the county. I have not as 

 yet seen specimens, and should be obliged to any botanist for 

 Wiltshire examples of this species, with 0. Hed'erce. 0. elatior 

 should be looked for njaoM Centaurea Scabiosa, chiefly on balks in 

 open chalky fields.
