Order CXXXV. STYLI'DEZ (plants agreeing with Sty- 
lidium in important characters). R. Br. prod. fl. nov. holl. 
p. 565. 
Calyx superior, 2-6-parted, bilabiate or regular (f. 123. a.), 
permanent. Corolla monopetalous, with a 5-6-cleft, irregular 
(f. 123. b.), rarely equal limb, which is imbricate in æstivation, 
and at length falling off. Stamens 2 (f. 123. d.); filaments 
combined with the style into a column. Anthers didy- 
mous (f. 123. d.), and sometimes simple, lying upon the stigma. 
Pollen globose, simple, sometimes angular. Ovarium 2-celled, 
but sometimes almost l-celled from the middle dissepiment 
being short, many-seeded ; furnished with a gland in front, or 
crowned by 2 opposite glands. Style one; stigma undivided or 
bifid. Capsule 2-valved, 2-celled, with a parallel dissepi- 
ment; or almost 1-celled from the dissepiment being short, 
or at length released from the inflexed margins of the valves. 
Seeds fixed to the axis of the dissepiment, erect, small, some- 
times pedicellate. Albumen conforming to the seed, fleshy, and 
rather oily. Embryo inclosed, minute.—Caulescent scarpigerous 
nonlactescent herbs or shrubs, beset with simple hairs, which 
are either tipped with capitate glands or acute. Leaves usually 
Scattered, but sometimes verticillate, entire, with naked or 
ciliated edges; radical leaves crowded in the scapigerous 
Species. Flowers spicate, racemose, corymbose, and solitary} 
terminal, rarely axillary ; pedicels usually furnished with three 
bracteas. 
This order is nearly allied to both Campanulacee and Goo- 
dendviee, from both of which it is distinguished by the gynan- 
drous stamens, and from the latter by the want of an indusium 
to the stigma. The structure of the sexual organs is highly 
curious; the stamens and style are closely combined into a solid 
irritable column, at the top of which is a cavity, including the 
stigma, and bounded by the anthers. 
Synopsis of the genera. 
1 Srytr'pium. Calyx 2-parted, bilabiate (f. 123. a.). Column 
with a double flexure. Anthers 2-lobed (f. 123. d.); lobes 
divaricate. Stigma undivided. Capsule 2-celled. 
2 Levennodxia. Calyx 5-parted, bilabiate. Column erect, 
adnate to the lower side of the tube. Lobes of anthers one above 
the other, divaricate. Stigmas 2. Capsule 1-celled. 
3 Forste’na. Calyx double, both composed of 2-3 sepals.

Lin. syst. Gyndndria, Diéndria. Calyx bilabiate (f. 123. a.). 
Corolla irregular, 5-cleft (f. 123. b.); the fifth segment or label- 
lum dissimilar to the others, deflexed, smaller, rarely stretched 
out; the rest spreading, rarely joined by pairs. Column recli- 
nate (f. 123. d.), with a double flexure. Anthers 2-lobed (f. 123. 
d.); lobes divaricate. Stigma obtuse, undivided. Capsule 2- 
celled, having the dissepiment sometimes incomplete above.— 
Scapigerous or caulescent herbs or subshrubs. Radical leaves 
crowded, sometimes attenuated into the petioles; cauline ones 
scattered, and sometimes verticijlate, often small and bractea- 
formed, rarely cirrhose at the apex or ‘loosened at the base. 
Inflorescence variable. Outer lip of calyx bidentate or bipartite, 
inner one tridentate or tripartite. Corollas purple, white, viola- 
ceous, rarely yellow, usually beset with pili on the outside, which 
are tipped with capitate glands: tube twisted at the base, some- 
times very short; throat usually crowned by teeth or glands, 
but sometimes naked: the 4 larger segments of the limb ap- 
proximating by pairs, one of the pair often smaller than the 
other. Labellum or lip narrower than the other segments, op- 
posite the front of the calyx, but from the contortion of the tube 
has at length become lateral, with its disk often thickened, and 
rather convex inside, usually appendiculated by a small segment 
on each side, but sometimes simple. Column linear, longer than 
the limb of the corolla, on the same side as the labellum, ex- 
serted, reclinate, having the outer bend so irritable that if touch- 
ed with a pin it instantly starts from its place to the opposite 
side of the flower with great impetuosity. Anthers dehiscing 
lengthwise. Stigma at first obsolete, and hidden by the incum- 
bent anthers, but exserted at length, and sometimes hispid or 
papulose.
