LIN. SYST. Pentdndria, Monogynia. Calyx profoundly 5- 

 parted (f. 77. a.), spreading, permanent, closed when in fruit. 

 Outer petals 5 (f. 77. 6.), equal, spreading, ovate, or ovate- 

 lanceolate, deciduous. Inner corolla monopetalous (urceolus ?), 

 ovate-conical, narrowed at the apex (f. 77. c.) and toothed, per- 

 manent, without any filiform appendages between the outer and 

 inner corolla. Stamens 5, alternating with the petals of the 

 outer corolla, but inclosed within the inner corolla ; permanent 

 filaments very short, adhering to the base of the inner co- 

 rolla ; anthers fixed by their base, elliptical, 2-celled, opening 

 lengthwise at the sides. Style erect (f. 77. rf.) permanent, 

 crowned by a scarcely manifest stigma. Ovary (f. 77. e.) 1- 

 celled at the top and 3-celled at the base, many-seeded. 

 Capsule ovate, 3-lobed, acute, 3-valved, and empty at the 

 top, but with the valves bent inwards at the base, even to the 

 centre of the capsule, therefore the capsule is 3-celled at the 

 base, dissepiments lunulately truncate, and bearing the seeds 

 at the top. Seeds, albumen, and embryo as in Sauvagesia, 

 Elegant, smooth, subshrubs. Leaves simple, on very short 

 footstalks. Stipulas lateral, twin, ciliated, permanent. Flowers 

 axillary or terminal, disposed in racemes, rarely in panicles, but 

 in both cases they are bracteate ; they are either white or red. 

 Parts of flowers twisted in the bud.

Calyx of 4 (f. 79. a.) but usually of 5 sepals (f. 81. 6.), con- 

 tinuous with the pedicel, never free, sometimes united together 

 into a tube, which is 4-5-toothed, constantly imbricate in aestiva- 

 tion, usually permanent. Petals equal in number to the teeth 

 or sepals of the calyx, and alternating with them, inserted 

 in a more or less elevated torus, unguiculate, with an entire (f. 

 80. d. f. 81. b.) or bifid (f. 79. rf.) spreading limb, usually 

 furnished with petal-like scales at the throat (f. 78. d. f. 79. c.). 

 These scales are seldom absent. Stamens equal in number with 

 the petals, or double that number (f. 79. e. f. 81.6.), inserted in the 

 torus, those that are alternate with the petals are much earlier 

 than the others and free, those that are opposite the petals are 

 sometimes adnate to their base, sometimes these last are abortive ; 

 filaments awl-shaped (f. 80. c.), sometimes monadelphous at the 

 base ; anthers 2-celled (f. 8 1 . e.), birimose, usually inserted by their 

 base. Ovary inserted on the top of the torus, simple, ovate, or 

 oblong (f. 81./.), 2-5-valved, crowned by an equal number of 

 stigmas (f. 81. g.), these are filiform or clavate, distinct from the 

 base, stigmatose and papillose inside. Capsule 2-5-valved,
