rrizozanthus, Xanthorhea, and Dianella, are instances in 
Monscotyledone, where he has substituted “ petalis ” for the com- 
odious “ perianthiis" of Mr. R. Brown. The last mentioned Bo- 
tanist indeed Peg to believe in this vegetable transubstantiation, 
though he differs with A. L. DE JussrEU, concerning the mode in 
which the miracle is performe d, renouncing that celebrated French- 
man's supposed origin of the floral Envelope. He says in the preface 
to his < * Prodromus, p p. vi. “ doctri rina. de — cal» yeind (minime de 
Sentonee mihi videtur ; risit um autem in Familie ‘ntegumento 
Jlorali simplice instructis pro calyce substitui ;’ " but a 
. 352 when falsely o my own de nitions 
on this head, forgets that under Seitaminea p p. 808, he had himself 
really fallen into that error; for notwithstanding they have two 
floral Envelopes of as different a nature, if we are to credit the usual 
evidence of our senses, as any in Dicotyledones, he calls both a Peri- 
anthium, which to adopt DRYANDER’S emphatical words respecting 
the passage, “is inconsistency with a vengeance.” As for analogy, 
Sane Amaryllis, Narcissus, Hemerocallis, Polianthes, Conval- 
a, Erythronium, Lilium, Tulipa, Colchicum, Crocus, Gladiolus, 
Tigridia, and Iris, all prove that to be in favour of my side of this 
citaminece, or Fluviales, is surely not less paradoxical, than it 
few interesting facts on the subject. The chief argument by which 
the venerable A. L. pz Jussrev, &c., support his opinion, namely the 
absence of an inner Bark in Monoco nocotyledones, i is completely subverted 
by several genera already mentioned, in the stems csi — an inner 
k is just as evident as in ‘yledones. The inner Bark more- 
over of all vegeta differs in nothing whatever fm the outer, 
know a single proof, that the Corolla is an — of it pts cn 
sively. On the contrary, several deviations from course 
of nature warrant me in believing, that the Calyx, Co uc Stamina, 
and Pistillum, are all an elongation of the outer Bark. The first 
is in Primula, which affords numerous instances, but the most 
ous and decisive is a variety of elatior, our common com 
which i is P in abundance every spring to Covent Garden mar 
ket, with a Calyx so exactly like the Corolla in colour, figure, - 
, that they cannot be distinguished. I have seen a second 
in Rosa Canina, w where the leaflets of the Calyx were flesh-coloured 
and iiec their dise, but green and calycine at their margin. 
A third instance occurred in Cheiranthus Cheiri, the Calyx 
of which was petaloid at the top with perfect polliniferous Anthers
