crown placed on the neck of the corolla uniting the bafes of 

 the ttamens, thus making it a diftincl appendage. Solander 

 Bank/. MJf* fpeaks of it ajs a fniall ne6tariform ringlet, created 

 by a flight cohefion of the dilated bafes of the filaments. 

 Tussieu, on the other band, calls the part we allude to, "faux 

 " prominens" and fays it is formed by the reflex curvature of 

 the bafe of the fegments, which afterwards becomes upright, 

 and adds, that it is Thunberg's ne£tary ; but here he is 

 wrong. — From all the above Botanilts we in fome meafure 

 diffent. The corolla we hold to be completely monope- 

 talous, and that there is no ne&ary confidered as a diftinft 

 appendage; but in many fpecies (of which the prefent is 

 the molt remarkable inftance known to us) the outer cuticle 

 detaches itfelf from the, inner and is rolled back for a greater 

 or lefs diftance; of this the fix flaccid fegments are the diftinft 

 and immediate continuation, fhrivelling almoft as foon as ex- 

 panded in our fpecies ; the upper part of the inner cuticle 

 thus bared affords the neclary-like appearance authors allude 

 to, and is (as are alio mofi probably the filaments) the feparate 

 and uninterrupted continuation of that membrane, the whole is 

 firmer, of a diftin£t colour, and remains in vigour until the ufual 

 procefs of impregnation is completed. — However wide the chafm 

 may appear between this and Massonia enfifolia> it is naturally 

 enough filled up by a feries of fpecies, in which the denuda- 

 tion of the faux gradually diminifhes till it difappears in enfi- 

 folia, where the bafes of the filaments are even below the 

 bafes of the fegments : as the faux decreafes fo the elongation 

 of the tube increafes, and the neclareous liquid finks deeper 

 and deeper till it is quite out of fight in enfifolia and 

 unijlora. The whole of this natural clafs is, according to 

 Jussieu's fyitem, corollalefs ;. but as it confifts of herbaceous 

 thin-rinded plants and fomewhat fucculent, we fufpe6l the outer 

 cuticle above mentioned is the continuation of the exterior 

 rind (cortex) too fine to produce a more fubftantial covering, 

 and that it correfponds with his Calyx ; that the inner one, 

 on the other hand, is the continuation of the interior rind 

 (liber) and that it may be his Corolla, both being thus united 

 to afford a fuffkiendy fubftantial protection to the parts of 

 fructification j if fo, the fame will apply to the whole clafs ; 

 it is evident in this genus the two coats are fpontaneoufly 

 feparable, of different degrees of duration, the inner one abid- 

 ing the procefs of impregnation, then withering. We merely 

 offer this hint for the prefent, nor do the limits of the work 

 permit the infertion of fome further obfervations we have made 

 on this fubjeft. Our drawing was made in die garden of
