 creeping below, clothed with hairy pubescence ; leaves opposite, 

 very unequal, one of which in each pair hardly exceeds a sti-

 pilose; peduncle terminal, 1-flowered. Q. S. Native of Java, 

 in woods on the higher mountains. 



One-flowered Argostemma. PL creeping. 



Cult. For culture and propagation, see Ophiorhiza, p. 523. 

 The species are all remarkable in their appearance. 



LXXII. SPIRADI'CLIS (from airtipa, speira, a spire, and 



-\(c, diclis, valves with folding doors ; in allusion to the valves 

 being divided into 2 parts, and also twisted at the apex). Blum, 

 bijdr. p. 975. D. C. prod. 4. p. 418. 



LIN. SYST. Pentdndria, Monogynia. Calyx with an oblong 

 turbinate tube, and a 5-toothed limb. Corolla with a short 

 tube, and a 5-parted spreading limb. Stamens 5, inclosed. 

 Style girded by 4 glands ; stigma 2-lobed in the throat. Capsule 

 oblong, crowned by the calyx, 2-celled, 2-valved ; valves bipar- 

 tite, at length twisted. Seeds numerous, angular. This genus 

 is nearly allied to Tula, with the tufted habit of Nertera. 

 Leaves opposite, ovate, rather undulated, glabrous. Spikes ter- 

 minal and lateral, few-flowered. Flowers small, secund, each 

 furnished with one bractea. 



1 S. C/ESPITOSA (Blum. 1. c.) Native of Java, at the foot of 

 Mount Salak in humid places. 



Tufted Spiradiclis. PL tufted. 



Cult. For culture and propagation see Tula below. 



LXXIII. TU'LA (like the rest of Adanson's names this is 

 also probably without a meaning). Adans. fam. . p. 500. Juss. 

 mem. mus. 6. p. 385. Roam, et Schultes, syst. 4. p. 25. D. C. 

 prod. 4. p. 418. 



LIN. SYST. Penldndria, Monogynia. Limb of calyx 5-toothed. 

 Corolla with an oblong tube, and a 5-cleft blunt toothed curled 

 limb. Anthers inclosed. Capsule 2-celled ; cells many seeded. 

 A small procumbent branched tufted herb. Leaves reniform, 

 petiolate. Pedicels axillary, short, 1-flowered. This genus was 

 alone known to Feuillee, and is therefore very doubtful. Habit of 

 Nertera, but differing in the flowers being pentamerous, and in 

 the cells of the fruit being many seeded ; it is perhaps, however, 

 01 ly that genus badly described.

 Native of Peru, on rocks by the sea-side. Soldanella facie, 

 Feuill. obs. 3. pt. 2. p. 63. t. 44. 



Adanson's Tula. PL tufted. 



Cult. A mixture of loam, peat, and sand will be a good soil 

 for this little plant ; and it may either be increased by cuttings 

 planted in sand under a hand-glass, or by seeds. The pot in 

 which it is grown should be half filled with sherds. 



LXXIV. DENTE'LLA (a dim. of dens, a tooth ; the lobes or 

 segments of the corolla are furnished with a small tooth on each 

 side). Forst. gen. p. 26. t. 13. Lam. ill. t. 118. D. C. prod. 4.

 globose tube, and a 5-cleft limb. Corolla funnel-shaped, 5-cleft ; 

 lobes furnished with a small tooth on each side ; throat hairy.

 thick. Capsule almost indehiscent, nearly globular, 2-celled, 

 crowned by the limb of the calyx. Placentas fleshy, prominent 

 on both sides within the cells. Seeds small, ovate. A creeping 

 tufted marsh annual herb. Stems filiform, glabrous. Leaves 

 oblong, glabrous, ciliated at the base, as well as the petioles. 

 Stipulas small, acute. Pedicels axillary, alternate, 1-flowered,

Creeping Dentella. Fl.July. Clt. 1802. PL creeping.
