Schwaegrichen’s Hypuum vesiculare was published in 1827; 
a good description of the species, together with figures, being 
given. The type-specimens collected in Jamaica, and preserved 
in Schwaegrichen’s herbarium, represent a rather small state of the 
species, with branches 3.5 mm. long, which, with the leaves,
