 all floriferous below. 



Adolphia, Meisn. — Cahjx campanulatus, brevis, ultra medium 

 5-fidus, laciniis acutis, iutus carinatis et callosis, festivatione 

 valvatis. Petala 5, ovata, cucuUata, imo unguiculata, stamina 

 amplectentia. Stamina 5, inter lacinias calycinas cum petalis 

 infra marginem disci inserta ; filamenta complanata, erecta, 

 apice inflexa ; anthercE rotuudatfe, cordatre, 2-lob?e, connectivo 

 reniformi dorsali affixae, rima liippocrepica 2-valvatim dehis- 

 centes, et hinc demum peltatim apertse. Discus crateriformis, 

 carnosulus, magnitudine tubi calycis, et ei arete adnatus. 

 Ovarium in fundura disci insitum, et paululo immersum, 

 depresso-globosum, 3-loculare; ovula in quoque loculo soli- 

 taria, erecta. Stylus hrevis ; 5^?^7?za obtusum, 3-lobum. Fruc- 

 tus capsularis, 3-coccus, ut in CoUetia. 



Frutex Mexicanus, ramosissimm, spinosus, ramulis oppositis, te- 

 retibus, sapius spina terminatis; spinis patentibus, decussatim 

 oppositis, rigidis; folia opposita, longe linearia, integoritna ; 

 flores solitarii, axillares, quasi fasciculati.

 integris, ci-assiusculis, pilosulis, demum glabrescentibus, sub- 

 tus pallidioribus, brevissime petiolatis ; stipulis parvis, oppo- 

 sitis, gibbosis, squamiformibus, fusco-rubellis, 2-fidis, laciniis
