is said to be exactly like that of Colletia, Adolphia, and some 
other genera of the ColletiecE. Brongniart’s remark* on this 
point is more conclusive ; for he states that Adolphia differs from 
Ceanothus and Colubrina in the form of its calyx and petals, its 
simple style, opposite leaves, and spinose branchlets, which are 
all floriferous below. 
Adolphia, Meisn. — Calyx campanulatus, brevis, ultra medium 
5-fidus, laciniis acutis, intus carinatis et callosis, aestivatione 
valvatis. Petala 5, ovata, cucullata, imo unguiculata, stamina 
amplectentia. Stamina 5, inter lacinias calycinas cum petalis 
infra marginem disci inserta ; filamenta complanata, erecta, 
apice inflexa ; anthera rotundatse, cordatse, 2-lobse, connective 
reniformi dorsali affixse, rima hippocrepica 2-valvatim dehis- 
centes, et hinc demum peltatim apertse. Discus crateriformis, 
carnosulus, magnitudine tubi calycis, et ei arete adnatus. 
Ovarium in fundum disci insitum, et paululo immersum, 
depresso-globosum, 3-loculare; ovula in quoque loculo soli- 
taria, erecta. brevis ; obtusum, 3-lobum. Fruc- 
tus capsularis, 3-coccus, ut in Colletia. 
Frutex Mexicanus, ramosissimus, spinosus, ramulis oppositis, te- 
retibus, seepius spina terminatis) spinis patentibus, decussatim 
oppositis, rigidis-, folia opposita, longe linearia, integeirima-, 
flores solitarii, axillares, quasi fasciculati.
