ANGIOSPERMAE—DICOTYLEDONES 



i6. Syrphus balteatus Deg.; 17. S. ribesii L. C. Hymenoptera. Apidae: 

 18. Andrena sp. 5, repeatedly, po-cltg. ; 19. Bombus terrester Z. $, freq., po-cltg. ; 

 20. Eucera longicornis L. t>, vainly searching for nectar; 21. Halictus albipes F. 5, 

 repeatedly, po-cltg. ; 22. H. cylindricus i^. $, do. ; 23. Megachile circumcincta .S'. 5. 

 D. Lepidoptera. Tineidae: 24. Micropteryx, sp., numerous (Budd.). 



The following were recorded by the observers, and for the localities stated. — 



Lindmann (Dovrefjeld), a nectar-seeking moth. Herm. Miiller (Alps), 2 beetles, 

 5 flies, and 4 bees. MacLeod (Pyrenees), 2 short-tongued bees and a fly (Bot. 

 Jaarb. Dodonaea, Ghent, iii, 1891, p. 323). 



2395. P. montana Huds. (Schulz, 'Beitrage,' II, p. 198.) — The herbarium 

 material of this species examined by Schulz bore a proportion of female flowers, and 

 seemed to be protogynous and anemophilous. 



2396. P. alpina L. (Herm. Miiller, ' Alpenblumen,' pp. 256-7; Loew, 

 ' Bliitenbiol. Floristik,' p. 396 ; Kirchner, ' Beitrage,' p. 58.) — The reddish coroUa- 



FlG. 347. Planlago alpina^ L. (after Herm. Miiller). A. A bud with projecting stigma, seen 

 from the side. B. Do., with parts separated. C, A homogamous flower (x 7). D. Pollen-grains, 

 further enlarged. E. A piece of the stigma. a, anthers ; Ar, bract ; Ji^ filaments ; ov^ ovary ; p, corolla- 

 lobes ; J, sepals ; .?/, stigma. 



lobes render the anemophilous flowers of this species tolerably conspicuous, so that 

 pollen-collecting insects are now and then attracted, and sometimes bring about 

 fertilization. The course of maturation of stamens and stigma varies between 

 homogamy and protogyny. The flowers observed by Kirchner near Zermatt were 

 protogynous with persistent stigmas, which still remained receptive when the anthers 

 dehisced.
