(2.) Viscum falcifrons, (Hook. et Arn.); ramis tereti- 
bus junioribus compressis, foliis anguste lanceolatis 
obtusiusculis recurvato-falcatis basi in petiolum attenu- 
atis obscure 3—-5-veniis, spicis axillaribus solitariis op- 
positis folio subduplo brevioribus, vaginulis truncatis.— 
Upon Laurels by the River Uraguay, Tweedie.—The 
vaginulz of the spikes are here formed of two opposite 
and equal portions: in V. Liga they are carinate at 
the back and acute at the extremity; in the present 
they are convex, without a carina, and the apex is trun- 
cate or rounded. We suspect that many species belong- 
ing to the tribe * ramulis ancipitibus compressisve,” 
are inserted by DeCandolle elsewhere.

(4.) Viscum ambiguum, (Hook. et Arn.); aphyllum, ra- 
mis teretibus inarticulatis evaginatis, spicis apicem versus 
ramorum alternis oblongo-linearibus evaginulatis, flori- 
bus trinerviis sessilibus squama concava obtusa paullo 
longioribus.—Upon Myrtles by the River Uraguay, 
Tweedie.—The flowers (of which we have only seen the 
female state) are very minute, and each situated on the 
spike, in the bosom of a concave scale. The whole, in- 
cluding the germen, is plano-convex, the inner or flat 
side being marked with a longitudinal furrow. The two 
lateral petals are carinate, the dorsal one nearly plane. 
Style short and thick; stigma truncated. In Viscum 
the margin of the calyx in the female flowers is usually 
. conspicuous, but in this species it is so entirely wanting

as almost to induce a belief that the three petals, which 
are apparently of the same texture as the tube of the 
calyx, form itslimb; and if this really were so, it ought 
to form a genus next to Tupeia, Cham. et Schl. (Lin- 
ned, v. 3. p. 203.), which seems in the same predica- 
ment.
