HAMAMELIS. Linn.

Char. Gen. Petala 4 , elongata, aestivatione valvato-involuta ! Capsula 
semiinfera, bilocularis. Semina solitaria. 
ORD. Nat. HAMARIELJDEiE, Br. 
Char. Gen. Petala elongata, aestivatione valvato-involuta ! 
Obs. Hamamelideae notis praesertim sequentibus distinguuntur. Flos semi- 
superus, completus, tetrapetalus. Stamina antherifera quatuor, petalis 
alternantia : Antheris basi insertis, biloeularibus, loculo singulo dehiscenti 
valvula unica medio semiseptifera, et vel altera sutura incompleta persistenti, 
vel utraque solubili decidua. Ovarium biloculare, loculis monospermis, 
ovulis pendulis (v. appensis). Styli duo. Fructus semiinferus, capsularis. 
Embryo longitudine fere albuminis : radicula supera. 
Huic ordini, cui referenda Hamamelis Linn., Dicoryphe Aub. Du Petit- 
Thouars , et Dahlia Tlninb., forsan adjicienda, in distincta tamen sectione, 
Fothergilla Linn., pericarpio, semine ? necnon habitu similis ; petalorum 
defectu, staminibus numerosis et dehiscentia antherarum diversa. 
Hamamelideae hinc affines, Bruniaceis, (ordo cui pertinent Brunia, Staavia, 
Linconia, Thamnea et Erasma,) ab iisdem distinguuntur autherarum inser- 
tione et dehiscentia, ovarii loculis monospermis, capsulae dehiscentia, floribus 
quadrifidis et habitu: inde accedunt Corno, Marleae Roxb. (qum Stylidium, 
Lour., fide exempl. ab ipso auctore,) generibusque affinibus, et quodammodo 
Araliaceis ; diversae structura antherarum, fructu capsulari aliisque notis.
