2277. O. Majorana L. (Kirchner, ' Beitrage/ pp. 54-5 ; Knuth, ' Bloemen- 

 biol. Bijdragen.') Such cultivated plants of this species as have been observed were 

 protandrous. The small white flowers do not protrude far beyond the green bracts, 

 which are arranged in four rows. Only the corolla-limb and the mouth of the flower 

 are visible, the corolla-tube, which is 4 mm. long and funnel-shaped, being hidden 

 between the bracts. The stamens project beyond the four almost equal corolla- 

 tubes, the two longer ones diverging laterally. When the white anthers dehisce, the 

 style with immature stigma is still hidden in the corolla-tube. After the anthers have 

 shrivelled, the style elongates so far that it projects 2 mm. beyond the corolla, and 

 presents its now diverging stigmatic branches to visitors.

2278. S. hortensis L. (Darwin, ' Diff"erent Forms of Flowers,' pp. 303-4 ; 

 Herm. Miiller, ' Weit. Beob.,' Ill, p. 56; Schulz, 'Beitrage,' II, p. 196; Breitenbach, 

 Kosmos, Stuttgart, xiv, 1884.) The flowers of this species are lilac or white in 

 colour, with red dots in the throat serving as nectar-guides. Breitenbach states that 

 there are three kinds of flowers, large hermaphrodite, small female ones, and some 

 with two reduced anthers. Darwin says that the plant is gynodioecious, and that the 

 female flowers are more fertile than the protandrous hermaphrodite ones. 



Schulz found 15-20 % of female flowers in plants cultivated at Halle.
