Obs. The following remarks relate to the modifications 

 of the different parts of fructification in Cyrtandrece and 

 their relative importance in characterising genera. 



The Calyx admits of every degree of depth of division. 

 Its segments are generally acute, always so when divided 

 to the base ; and wherever acute the aestivation appears to 

 be valvular. In several cases where the calyx is tubular, 

 particularly in the greater part of true Didymocarpw, and 

 in one of the sections of Mschynanthus, the segments are 

 rounded, and the aestivation necessarily overlapping. The 

 tubular calyx, when accompanying an elongated capsule, is 

 generally thrown off or separates tranversely at the base, 

 except in the few cases in which the capsule is pedicellated. 

 The deeply divided calyx of the genera with elongated 

 capsules is persistent ; as it also is, whether deeply divided 

 or tubular, in all those with short capsules and in the 

 n3] baccate genera. None of these modifications appear to 

 be of generic value, though some of them form the principal 

 characters of very natural sections of genera. 



The tube of the Corolla varies greatly in length, but 

 its various proportions, either with respect to the limb or 

 calyx, are seldom of generic importance; a difference of 

 this kind, however, forms the only distinguishing character 

 between Bcea and Streptocarjms. The limb varies con- 

 siderably in form, direction, and proportion of lips ; but 

 the most important modification occurs in Glossanthm and 

 Lozotis, in both of which the lateral lobes of the lower lip 

 are obsolete ; or, in the former genus, perhaps, altogether
