THE ANDRUCIUM. AOD 
Meiotaxy of the andrecium—Complete suppression of 
the stamens occurs normally in the female flowers of 
unisexual plants, and, as an accidental occurrence, is 
not very uncommon. Iiricw Tetraliw is one of the 
plants in which this is said to happen. ‘The variety 
anandra is said to have been known in France since 
1635. Cornuti speaks of it in his ‘ Enchiridion.’ In 
1860 M. du Parquet discovered it in peaty woods near 
Nangis (Seine et Marne). 
Many Umbelliferce, such as Trinia vulgaris, present a 
like deficiency, while it is of common occurrence 
among ftosacew and Pomacee. In the latter group 
the St. Valery apple, so often referred to, is an illus- 
tration. ‘To obtain fruits from this variety it is neces- 
sary to apply pollen from another flower, a proceeding 
made the occasion of festivity and rejoicing by the 
villagers in some parts of France. In some of the 
Artemisias, especially in Artemisia Towrnefortiana, all 
the florets have been noticed to be female, owing to 
the suppression of the stamens, and this suppression 
is associated with a change in the form of florets.’ 
Mr. Moggridge has communicated to the author flowers 
of Thymus Serpyllum from a plant in which all the 
stamens were deficient, the flower being otherwise 
normal, 
M. Dupont has given a list of nineteen species of 
Chenopodiacece in which female flowers are occasionally 
produced, owing to the entire suppression of the 
staminal whorl. 
Flowers the subjects either of regular or irregular 
peloria, g. v., are often destitute of some or all their 
stamens, ¢. 7. Calceolaria, Linaria, Viola, &e., while in 
cases of synanthy suppression of some of the parts 
of the flower, and specially of the stamens, is of very 
common occurrence. 
Suppression of the andrceecium as a teratological 
occurrence has been most frequently noticed in the 
' Moquin-Tandon, loc. cit., p. 328.
