FLORAL, STRUCTURE AND AFFINITIES OF SAPOTACEiE. 69 



and those of the next but one." * In this last case, the two latter 

 whorls may be viewed as forming a false whorl, and the new 

 one may be termed an augmented whorl. The androecium of 

 certain species of Bassia, of Pijcnanclra, Crijptogjjne, and Omphalo- 

 carpum, still appear to me abnormal, or at least to need further 

 explanation. 



As regards the classification of the Order, we find three well- 

 marked divisions, as follows — the names being on the whole those 

 of Bentham and Hooker's ' Genera' : — 



I. IsoNANDRE^. — Petals exstipulate ; stamens all fertile (in- 

 cluding Isonandra, DicJwpsis, Pi/cnandra, Bassia, Dasyauhts, 

 Paijena, and Lahourdojmaisia as limited by Bojer. 

 II. Chrysophylle^. — Petals exstipulate ; alternipetalous stamens 

 sterile or abortive (including Chrijsophijllum, EccUnusa, 

 Lucuma, Sarcosperma, Sideroxijlon, Argania, Labatia, 

 Achras, Butyrospermum, Leptostylis, Cryptogyne (?), He- 

 noonia (?) 

 III. MiMusoPE^. — Petals with lateral appendages ; alternipetalous 

 stamens fertile in EicMeria f only (including Mimusops, 

 Imbricaria, Eichleria, Labramia, Bunielia, and Dipholis). 



The structures and arrangements above described are exhi- 

 bited in the following diagrams : —
