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-

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

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



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 '^'^- 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 '^'^- long), 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.
