1193. C. bulbosum L. — Kirchner (' Flora v. Stuttgart,' p. 396) describes this 

 species as andromonoecious, with a similar distribution of sexes to that of C. temulum. 

 The quaternary umbels, which develop late, are almost always completely male. 



Visitors. — Loew (Berlin Botanic Garden) observed the bee Prosopis armillata 

 Nyl. 5, skg. 



1194. C. aureum L. — According to Schulz (' Beitrage,' II, p. 191), this species 

 is also andromonoecious, with protandrous hermaphrodite flowers.

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



MacLeod (Pyrenees), 7 short-tongued Hymenoptera, 5 beetles, 6 Syrphids, and 

 17 other Diptera (Bot. Jaarb. Dodonaea, Ghent, iii, 1891, pp. 415-16). von Dalla 

 Torre (Innsbruck Botanic Garden), the bee Prosopis annulata Z. 5 and $. 



1195. C. aromaticum L. — Schulz (' Beitrage ') describes this species again as 

 andromonoecious, with protandrous hermaphrodite flowers. According to Kerner 

 (' Nat. Hist. PI.,' Eng. Ed. i, II, p. 295), each umbellule contains a central and 3-5 

 marginal hermaphrodite flowers, the intermediate space being occupied by about 

 20 pseudo-hermaphrodite male ones. The hermaphrodite flowers develop earlier than 

 the male ones, their anthers having fallen off and their stigmas matured before 

 dehiscence takes place in the latter. The stigmas come into the line of fall of the 

 pollen of the male flowers, and are thus geitonogamously crossed. {Cf. Fig. 155, 

 p. 463, and Vol. I, pp. 41-2.) 



1196. C. hirsutiun L. — Schulz ('Beitrage,' II, p. 191) describes this species 

 also as andromonoecious, with protandrous hermaphrodite flowers.
