2135. V. Ponae Gouan. (MacLeod, ' Pyreneenbl.,' p. 38.) The flowers of 

 this species are reddish-violet in colour. 



Visitors. MacLeod observed 4 Diptera (a Bombylius, 2 Syrphids, and an 

 Empid) [in the Pyrenees. 



2136. V. gentianoides Vahl. 



Visitors. Loew observed the Dermestid beetle Anthrenus scrophulariae Z. in 

 the Berlin Botanic Garden. 



2137. V. Sanderson!. (Ludwig, Biol. Centralbl., BerHn, vi, 1886-7.) 

 Ludwig describes this species as bearing protandrous flowers, in which at first the 

 corolla is bright red, the filaments and style being also red, and about 7 mm. long. 

 Later on these parts become white, and the style elongates to 13 mm.

665. Paederota L. 



2138. P. Bonarota L. (Loew, ' Bliitenbiol. Floristik,' p. 50 ; Kerner, * N; 

 Hist. PI.,' Eng. Ed. i, II, pp. 334-5.) This species is native to Camiola, Carinthi 

 and adjacent regions. Loew examined cultivated plants, and found the flowers to be 

 homogamous. The corolla-tube is 4 mm. long. Kemer says that the anthers do 

 not at first reach the level of the stigma, but subsequently attain this by elongatio^ 

 of the filaments, so that automatic self-pollination takes place. 



2139. P. Ageria L. (Kemer, op. cit., p. 402.) This species is native to 

 Camiola and Lower Steiermark. Kerner observed plants cultivated in the Innsbruck 

 Botanic Garden to be infertile. Automatic self-pollination is excluded. 



666. Wulfenia Jacq. 



2140. W. carinthiaca Jacq. This species is native to Upper Carinthi 

 Cultivated plants observed by Hildebrand and Loew were protogynous. 

 pollination is possibly excluded. 



667. Tozzia L. 



Homogamous or feebly protogynous fly flowers; with nectar secreted by the 

 base of the ovary. 



2141. T. alpina L. (Herm. Miiller, ' Alpenblumen,' pp. 277-9.) The flo^ 

 of this species are homogamous or feebly protogynous. The three lower lobes of I 

 brilliant yellow corolla present dark purple blotches serving as nectar-guides. Nect 

 is abundantly secreted, and is easily accessible to insects with a proboscis only a fel 

 millimetres long. At first the style projects considerably beyond the stamens, so th 

 insect visitors touch the stigma before the anthers. During subsequent growth
