the seed of which was not then known ; so that it is more than 

 probable that the two genera are identical. This opinion is 

 confirmed by some of the specific characters given in the ' Pro- 

 dromus/ — for instance, in the punctate hollows mentioned in 

 the axillary nodes of his P. foveolata, which exist in many spe- 

 cies of Adenocahjmna, and which I have not observed in any 

 other genus, DeCandolle, however, describes the capsule as 

 being somewhat flatly compressed and smooth : the flattening of 

 the valves in the dried specimens may probably arise from their 

 warping in desiccation, as I have observed in those of Adeno- 

 calymna; and the tubercular rugosities, as described in my 

 plants, may be only a specific character -, but it is impossible to 

 determine these points without comparative examination. Ade- 

 nocalymna must be placed in the division Monostictides of De- 

 Candolle, not among the Pleiostictides, where he arranged it. 

 The following is an emended diagnosis of the genus : — 



Adenocalymna, Mart. — Calyx tubuloso-campanulatus, coria- 

 ceus, ssepius 5-dentatus, rarius fissus, versus apicem glaudulis 

 grossis disciformibus viridibus semi-imraersis instructus. 

 Corolla tubulosa, imo coarctata, hiuc inde subcampanulata, 

 extus ssepius pulverulento-velutina, limbo 5-lobo, lobis sub- 

 ffiqualibus, rotundatis, quorum 3 erectioribus. Stamina 4, 

 didynama, inclusa, cum 5*° sterili inter 2 breviora ; filamenta 

 filiformia, glabra, apice incurva ; anther ce. per paria conniventes, 

 singulse 2-lob3e, lobis oblongis, apice affixis, segregatis et 

 divaricatissimis, flexione filamentorum axi parallelis. Ovarium 

 oblongum, rugulosum, 2-loculare, pluriovulatum, disco pul- 

 vinato suff*ultum : stylus filiformis, glaber, longitudine sta- 

 minum : stigma bilamellatum. Capsula cylindrica, botuli- 

 formis, ssepe tuberculis elevatis poriferis subserialibus rugosa, 

 2-locularis, 2-valvis, valvis coriaceis dissepimento crasso par- 

 allelis, replo bipartibili utrinque subtenui a valvis solubili. 

 Semina plura, in utroque margine dissepimenti 1-seriata, 

 transversa, magna, crassa, aptera, crebre coarctata, vix imbri- 

 cata, compresse suborbicularia, dorso convexiuscula, ventre 

 subangulata, hilo pergraudi ovali versus basin notata : testa 

 dura, Crustacea, nitida, longitudinalitcr 2-locularis, septo in- 

 tegro coriaceo foramine centrali pro radicula3 receptione fe- 

 nestrato : iategumentum internum conforme : embryo exalbumi- 

 nosus, testa configuratus,'/o6is cotyledonaribus 4, crassis, car- 

 nosis, plano-convexis, per paria adpressis et in loccllis integu- 

 mentorum nidulantibus, radicula perparva, tereti, loborum 

 quarta parte lougitudinis, centro inter cos prorsum adnata, et in 

 foramine septi recondita, oblique et horizontaliter centrifuga.
