Memoranda of an Excursion 
9^9 
As they did not, however, assemble together till near 
evening, I had a little time to botanize, and which, I 
trust, I fully used. It was, indeed, a lovely spot: that 
constant humidity, so requisite for the full development 
of the varied tribes of the Cryptogamic Family in all 
their beauty, was ever-present in these umbrageous so¬ 
litudes. Commencing at the water’s edge, I gathered 
specimens of a peculiar Rumex- like herbaceous plant, 
which grew within the water. Close by a small Mgr- 
taceous shrub, clothed with Lichens and Jungermannice , 
attracted my notice; this shrub attained to the height 
of seven feet. Several beautiful Mosses and Junger- 
mannice , next entered my vasculum. A beautiful folia- 
ceous Lichen grew here on the trunks of living trees, 
having spherical black soredice on its under surface, 
which appeared quite unique. Another fine species, 
bearing scutellce on the edges of its thallus , grew also on 
these trees. I here obtained fine specimens of A. Cun¬ 
ningham’s new genus Ixerba; and, in doing so, almost 
dared to hope that I had gained a second species of this 
peculiar and handsome genus. This differs from I. 
Brexioides, Cunningham’s plant, in its anthers being 
almost elliptical scarcely ovate, its twisted style, its 
larger corymbs containing 5-10 flowers, its lanceolate 
leaves shorter and broader, its much larger size, and 
robust habit, attaining the height of 40-50 feet, and 
being, too, one of the commonest trees of these woods.* 
* Ixerba brexioides, Cunningham’s plant, is, in these particulars, 
thus described by him:—“ Antherce ovatm acuminatae. Stylus, 1, an- 
gulatus, continuus, versus apicem attenuatus. Flores, corymbosi, pe- 
dunculis (uncialibus) plerumque trichotomis. Folia , elongato-lanceo- 
lata acuminata, 4-5 uncialia.” [5-6£, IV. C T .] n Arlor clegans viginti 
pedalis et infra. A tree of very rare occurrence.”-— A. C. in Ann. Nat. 
Hist. Vol. iii., p. 250.
