of the Stamina of Plants. 1 
parts in animals, the G/ans Penis and Clitoris, being like them 
flaccid and evanescent when the business of impregnation is 
over: for from above 500 experiments, made by carefully taking 
away the Corolla while the flower was very young, I have kaad 
its presence to be of more importance than has been usually sup- 
posed. The remaining similarities are so obvious, and so empha- 
- tically described by our great master in his Sponsalia Plantarum, 
that I need not recall them to your memory. I would therefore 
define the Calyx, Involucrum floris exterius, herbe plerumque colore 
et substantid consimile, toro insertum, staminibus semper discretum : 
and the Corolla, Involucrum floris interius, herbe plerumque colore 
et substantià dispar, toro insertum, staminibus vel conjunctum vel in 
eodem puncto ortum. In the last definition I. have entirely omitted 
the situation of the Stamina as being alternate with the divisions 
of the Corolla, this distinction proving. too inconstant for a pri- 
mary character; a far more certain one is obtained by referring 
to their conjunction with it and joint termination. ‘The Gals 
being thus reduced within its natural limits, and the Receptacle 
brought forward to its long-neglected rights and honours among 
the other parts of the flower, the difficult and ambiguous Inser- 
tions, which Jussiew has stated with so much candour and inte- 
grity, vanish ; and all the Natural Orders which agree in that re- 
spect may be arranged in one continued series. Moreover, when 
only one Involucrum is present, and the common analogi 
colour, figure and consistence fail, far less, i: ifficulty will 
occur in determining it: thus in Profee, which have the Stamina | 
inserted near the top of the Involucrum, it. is indubitably a true 
Corolla; while in Atriplices which have the stamina inserted in — 
the receptacle, it is as surely a true Calyx, exactly corresponding 
with that of Amaranthi; in fact, Atriplices and Amaranthi are 
only divisions of one and the same Natural Order. It now only
