2286. C. Nepeta Savi. (= Melissa NepetaZ.). (Herm. Miiller, ' Alpenblumen,' 

 p. 321; Schulz, 'Beitrage,' II, p. 196.) This species is gynodioecious with large 

 hermaphrodite and small female flowers. Schulz says that it is sometimes gyno- 

 monoecious in the South Tyrol, with about 25 % female flowers.

Herm. Miiller (Alps), 5 humble-bees, a fly, and 5 Lepidoptera. Loew (Berlin 

 Botanic Garden). A. Diptera. Syrphidae : i. Eristalis nemorum Z. B. Hymeno- 

 ptera. Apidae : all skg. : 2. Apis mellifica Z. 5 ; 3. Bombus agrorum F. $ ; 

 4. B. terrester Z. i ; 5. Psithyrus vestalis Fourcr. 5 and $. 



2287. C. grandiflora Moench. Schulz says that the hermaphrodite flowers 

 of cultivated plants of this species (indigenous to Croatia and the Siebengebirge) are 

 protandrous. Female stocks also occur. 



2288. C. umbrosa Fisch. et Mey. 



Visitors. Loew (Berlin Botanic Garden) observed the humble-bee Bombus 

 agrorum F. 5, skg. and po-cltg. 



2289. C. Clinopodium Benth. (= C. vulgare Z.). (Herm. Miiller, 'Fertili- 

 sation,' p. 476, 'Alpenblumen,' p. 321 ; Schulz, ' Beitrage,' p. 83, II, pp. 135, 154, 

 196; Kirchner, 'Flora v. Stuttgart,' p. 614; Knuth, 'BloemenbioL Bijdragen'.) 

 Hermann Miiller describes the corolla-tube of the purple-red flowers of this species 

 as 10-13 mm. long, and not infrequently filled to a height of 3 mm. with nectar. 

 The lower stigmatic branch of the style is a broad, lancet-shaped plate bending 

 downwards and devoid of noticeable papillae ; the upper is much narrower and 

 shorter, and even almost absent. Schulz states that there are two different forms 

 of hermaphrodite flowers (i) Large (16-17 mm. long), strongly protandrous, and 

 (2) small (12-13 ^^^- lo^g)> feebly protandrous, rarely homogamous. The female 

 flowers also vary in size ; sometimes they are associated with hermaphrodite ones on 

 the same plant, sometimes they are only found on separate stocks. Schulz occasion- 

 ally saw the flowers perforated by Bombus terrester Z. and B. lapidarius Z.
