6 Mr. SArisBUnRY on the Perigynous Insertion 
whether it be one or two, should in future be described by the 
common name of Perianthium, including both Calyx and Corolla 
under that appellation. Ventenat in the Magasin Encycl. lre 
année, tome xi. gives as an essential characteristic of the Corolla its 
Trachee or spiral vessels : but to say nothing of the practical dif- 
ficulties attending such a distinction, they have since been found 
not only in some true and legitimate Calyces, but even in the Brac- 
tee of Strelitzia by Mr. Bauer; from whose observation as well 
as my own I am quite convinced that they are not the common 
tubular vessels of the plant in a state of decay, as Mirbel sup- 
poses. Adanson noticed these T? ache in his Familles des Plantes 
Jong before Ventenat, quoting the original observer, Saussure. 1 
believe I have now mentioned all the opinions hitherto promul- 
gated on this subject, none of which have ever appeared quite 
satisfactory to me: for, the overpowering similarity between 
many Monocotyledonous and Dicotyledonous flowers forcibly with- 
holds me from distinguishing them 
whilst the widely different organization of their Stems totally 
-overturns the Linnean hypothesis of the Corolla being invariably 
a continuation of the Liber or inner bark. In this difficulty I 
have.no guide but analogy to lead my dim and imperfect re- 
searches after the truth: yet it is from pure analogy, that we 
dare to entertain some of the most sublime opinions; for, what 
astronomer doubts of the numerous stars before him being inha- 
bited ? .1 therefore consider all the different parts of the flower 
as proceeding: from 
animals have one common origin under the Venter.’ Of these 
parts, the Calyx, or oiftet cover, answers pretty nearly to the Pre- 
putiun and Labia Pudendi, being like them continuous with the 
exterior muscles of the whole. individual: the Corolla, or. inner 
cover, seems to have no less analogy w ith the two next. important
