Lindl. bot. reg. t. 1962.
Tube of the calyx prolonged beyond the ovary, filiform, deciduous ; the
limb 4-parted. Petals 4, unguiculate, 3-cleft. Stamens 4, opposite the sepals:
filaments filiform-subulate, shorter than the petals : anthers oblong, fixed

by a short cylindrical disk : stigma 4-lobed, 2 of the lobes smaller. Capsule
oblong-linear, somewhat cylindrical, 4-celled, 4-valved. Seeds numerous,
imbricated upwards, with a narrow membranaceous wing-like margin.—A
small annual ascending herb, with opposite or mostly-alternate ovate petio-
late entire leaves. Flowers axillary, sessile, about the length of the leaves :
petals purplish-rose-color, marked with 3 white lines and 2 purple spots.
E. condnnum (Fisch. & Meyer, 1. c.)

Subtribe 3. Gaurineæ, Spach.—Calyx deciduous from the summit of
the ovary after flowering. Petals somewhat unequal or turned to one side.

8. GAURA. Linn. ; Geertn. fr. t. 127 ; Lam. ill. t. 281.
Gaura & Schizocarya, Spach.
Tube of the calyx much prolonged beyond the ovary, cylindraceous or
sometimes infundibuliform, deciduous ; the segments 4, or rarely 3, about
the length of the tube, reflexed. Petals 4, rarely 3, unguiculate, mostly a
little unequal or one-sided. Stamens 8, rarely 6, somewhat declined; those
opposite the petals a little shorter : anthers fixed near the middle. Ovary 4-
(rarely 3-) celled, with 1-2 suspended ovules in each : style filiform, declined
or deflexed, thickened at the apex ; stigma 4- (rarely 3-) lobed. Fruit
3-4-ribbed or angled, somewhat ligneous* indehiscent and nut-like, or sometimes
2-4-cleft at the apex, usually by abortion 1-celled and 1-4-seeded.
Seeds not appendiculate or comose.—Perennial, or sometimes annual or
biennial, herbs, or suffruticose plants, with entire or toothed mostly sessile
alternate leaves. Flowers in terminal spikes or racemes: petals white or
rose-color, usually changing to red.

obtuse ribs, and 4 inconspicuous intermediate ones, slightly acuminate, tapering
at the base, almost sessile.—Linn. ! spec. 1. p. 347 ; Lam. ill. t. 281 ;
