Sepals combined into a 4-7-toothed or lobed c a ly x ; the lobes
valvate or distant in asstivation; the sinuses sometimes produced
into accessory lobes or processes. Petals alternate with the proper
lobes o f the calyx and inserted on its throat, very deciduous, sometimes
wanting. Stamens inserted into the tube o f the calyx below
the petals, equal to them in number, or 2 -4 times as many, rarely
fewer : anthers short, introrse. Ovary enclosed in but free from
the calyx, 2-4-ce lled , with numerous ovules in each c e l l ; the
placentae in the a x is : sty le filiform, sometimes short or almost
n on e : stigma usually capitate. Capsule membranaceous, surrounded
by the calyx, often 1-celled by the obliteration o f the dissepiments,
dehiscent either longitudinally or irregularly. Seeds numerous and
small, or rarely few and large, anatropous, destitute o f albumen.
Cotyledons flat and foliaceous.— Herbs, rarely shrubs or trees, with
usually 4-sided branches, and opposite or seldom alternate entire
exstipulate leaves, without glands or dots. Flowers axillary, or
(by the reduction o f the leaves) in terminal racemes or spikes.
Lagerstrcemia Indica occurs in Drummond’s New Orleans collection; but the
plant has probably escaped from the gardens.
1. HYPOBRICHIA. M. O. Curtis, mss. (1836)
Ptilina, Nutt. mss. (1838)
Calyx hemispherical-campanulate, not bracteolate at the base, 4-lobed:
accessory teeth none or mere callous points. Petals none. Stamens 2-4.
Ovary globose, 2-celled: style almost none: stigma 2-lobed. Capsule
globose, very thin and membranous, 2-celled, bursting irregularly: placenta
globose, thick. Seeds numerous (rather large for the size of the capsule),
obovate-oblong, ascending; the testa membranaceous.—A submersed aquatic
herb (with somewhat the habit of Callitriche autumnalis), with opposite
and crowded linear pellucid leaves, and minute axillary sessile flowers.
Except in its peculiar habit, this plant differs very little from Ammannia Mr
Durt:s sent us specmens several years since, under the present name, and with
an accurate description; but he was not aware of its identity with the Penlis
diandra of Nuttall. F
