CARYOPHYLLEAE 195 



gynodioecious, more rarely gynomonoecious. At Ruppin, according to Wamstorf, 

 there are hermaphrodite flowers of two sizes, respectively 15 mm. and 10 mm. in 

 diameter. The small-flowered variety is further characterized by the possession 

 of glandular hairs on the stem, especially on the upper part of this.

Herm. Miiller saw 20 Diptera, 2 bees, and 3 Lepidoptera in the Alps ('Alpen- 

 blumen,' p. 171).

MacLeod saw a bee, an ant, 3 Syrphidae, an Empid, and 7 Muscidae in the 

 Pyrenees (Bot. Jaarb. Dodonaea, Ghent, iii, 1891, p. 378), and 4 Diptera, a Lepi- 

 dopterid, and a beetle in Flanders (op. cit., vi, 1894, p. 167). 



In Dumfriesshire, several Diptera have been recorded (Scott-Elliot, ' Flora of 

 Dumfriesshire,' p. 27). 



484. C. triviale Link (=C. vulgatum Z. and C. caespitosum Gilib.). (Axell, 

 ' Om Anordning. for Fanerog. Vaxt. Befrukt.,' pp. 16-17 ; Herm. Miiller, ' Fertilisa- 

 tion,' p. 132; Kirchner, 'Flora v. Stuttgart,' p. 240; Schulz, 'Beitrage,' I, p. 24.) 

 Hermann Miiller says that the flowers have the same mechanism for pollination 

 as those of C. arvense, but they are smaller, in accordance with which protandry 

 is less pronounced, and the visits of insects less numerous. Failing insect-visits, 

 automatic self-pollination takes place and is effective (Axell). The stamens of the 

 hermaphrodite flowers are often more or less vestigial. Protogyny has been observed
