ssienatiate on depriving Flowers of their Anthers. 47 
four. No stamen, or rudiment of the germ, was discovered in the 
lai of the flower, The Sie are the most nierenieg re- 
marks on the subject. 
1. To succeed in these experiments, you must cut out the cated 
from the closed flower, when they are almost formed, but have not yet 
spread out the pollen. The Gillyflower (Cheiranthus annuus) suc- 
ceeded in the best manner, just when the petals were about 33-4” 
(linee Parisienses) long, already a little colored, but still closed and 
folded; the petals must rts cautiously be opened witha payontiay . 
and the anthers taken out. 
2. If you cut off the saileage when the pollen is already spread out 
in some measure, then large and perfect pods are produced, but the 
_ single flowers are mingled with double ones. 
3. If you take them before the anthers are formed, and the ied 
still colorless, or only whitish green, and about 1-14/” (Paris meas- 
ure) in length, standing out of the calyx, then no seed at all is pro- 
duced, and the germ after some time drops off sterile. This obser- 
vation proves that the fructification must be acbarding to the : 
method certain, though imperfect. 
_ 4. If you observe the further growth of as oade th sk daceed 
flowers, you will remark, that they grow less regular than natural 
ones; they thicken and swell up, sometimes on the upper more than 
on the under part 5 they are jpegs shorter than ae and vary 
very much in size on the same plant 
_ 5. In the state of maturity, you find less seeds in pods of mutila- 
ted flowers than in those not so. We find the seeds sometimes only 
attached to one side, the other side of the dissepiment being empty 5 
sds contained. from five.to seven seeds, when natural ones 
“4 curved, and imperfect : ‘the weight of one thousand ordinary 
seeds of the Gilly flower, in a dry state, attached for ten months to 
the dissepiment, was in the month of aul 26 grains. One seed 
had a weight of about .026 gr. or near to ;'; gr- ‘The same num- 
ber of seeds from double flowers was 22 6 24 a ; single seed, 
. We observed sometimes, in natural pods of the Cheiranthus 
he curved and imperfect seeds, which produced double flow- 
ers also. i
