By this rule the tube and six segments of a Narcissus, t. 17, 275 and 276, constitute the Calyx, and then surely what Jussieu calls a Crown, and Linnæus a Nectary, must be allowed the name of Corolla. On the other hand, the Spatha becomes a Bractea. Consequently the whole order of Liliaceous flowers in general have a coloured Calyx only, which seems hardly admissible; and yet I cannot conceal a recent discovery which strongly confirms the opinion of my acute and candid friend. Two species of a new genus, found by Mr. Menzies on the West coast of North America, have beautiful liliaceous flowers like an Agapanthus, with six internal petals besides! I must however protest against the idea of the Corolla originating exclusively from the inner bark, as well as of the cuticle not being continued over it, for reasons sufficiently apparent from the former part of this work.
It is a Linnæan rule that the Stamens should be opposite to the segments of the Calyx, and alternate with the parts of the Corolla. Its author nevertheless seems of
