with close parallel pinnatiform veins, and tufts of numerous, descending, 
simple, villous roots. Capsules membranous, indehiscent, globose, 
clustered in descending panicles, singly at the end of short pedicels, 
borne among the roots, the smaller, which are fewer, superior, and on 
longer pedicels, containing few reticulated macrosporangia ; the larger, 
inferior, more numerous, on shorter pedicels, containing multitudinous, 
reticulated microsporangia. 
Like the next, all the plants of this genus bear a 
common general resemblance, differing mainly in the 
degree of elongation of the axis, and size, form, colour 
and vestiture of the leaves, &c. The capsules are 
globose, and hang in loose clusters among the leaves, 
each one on separate pedicels which radiate more or 
less from the common axis. Those containing the 
macrosporangia, though situated above, reach out beyond 
those containing the microsporangia, which are larger, 
having pedicels twice or more as long. The fruit, roots, 
and fronds all spring from the joints in the rachis, which 
is the thickness of moderately thin string, the interven- 
ing space being destitute. 
1. Salvinia auriculata, Aulet. Guian. ii. 969, t. 367. Baker 
Jour. Bot. vol. 24, p. 99. — Rachis horizontal, cord-like, nearly a line 
thick, puberulous with slight scales, extending a few inches and branch- 
ing. Fronds contiguous or apart, two at each joint, spreading at right 
angles, on petioles i-% in. 1. which are clothed like the rachis, the blades 
folded at first, rounded, cordate at the base with rounded auricles, 
i-|ths. in. each way, herbaceous, cloudy-green, pubescent beneath, 
densely strigose above with elongated glands that are divided into three 
or four filaments at the end, and mixed with finer ones ; veins very 
close and numerous. Capsules of microsporangia nearly 1 li. diameter 
about 2-6 in number, those of the macrosporangia half the size and 
about 1 -3 ; both pubescent. 
Var. S. Olfersiana, Klotzsch. — Fronds crowded, sessile, half as large 
Veinlets fewer. 
Most abundant throughout the coast region of Guiana,
