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

 stated. — 



Schulz (S. Tyrol), Lepidoptera and long-tongued bees. Knuth (Capri, early 

 April, '92), 2 bees — Anthophora femorata Oliv., and A. pilipes F. 5 and S. With 

 extended bodies and loudly humming they flew very rapidly about in the mature 

 flowers, usually only touching them for a moment with their forelegs (more rarely 

 clinging to them), and probing them deeply with their long, widely extended proboscis. 

 They did this with great rapidity, and as quickly hurried away to visit a distant plant 

 of the same species. To catch some of these bees was a very tedious matter. Friese 

 (Fiume), 2 bees — Andrena juUiani Schmiedekn., and A. tscheki Mor. 



2789. M. tenuiflorum Tausch (= M. comosum Mill., according to the Index 

 Kewensis). (Schulz, op. cit., I, p. 99, II, p. 200.) — In this species the grey-greenish- 

 brown flowers, with a touch of violet, are feebly protogynous. As the stigma is 

 situated just beneath or between the anthers, automatic self-pollination is easily 

 possible. There are also flowers with reduced pistils above those with complete 

 stamens and carpels, and other apical, long-stalked, bud-like ones, completely closed, 

 and serving only for attraction. 



3790. M. racemosum Mill. (=Hyacinthus racemosus L). (Herm. Miiller, 

 ' Weit. Beob.,' I, p. 278; Schulz, op. cit., II, pp. 168-70.) — The perianth in this 

 species is about 6 mm. long and 3 mm. broad, and dark-violet in colour. The 

 flowers are protogynous, the stigmas being mature before anthesis. The anthers 

 are at first apposed to the perianth, and bend later towards the stigma, so that 

 automatic self-pollination takes place. Insects searching for the sparingly secreted 

 nectar at first efi"ect cross-pollination more easily, touching stigma and anthers with 

 opposite parts of their bodies. Above the normal flowers are partially reduced ones, 

 and at the top 3-9 completely neuter open ones.
