LIN. SYST. Tetra-Hexdndria, Monogynia. Calyx with an 

 obovate-globose tube, and a very short entire or 4-toothed limb, 

 rarely 5-6-toothed. Corolla with a short nearly terete tube, 

 and 4-6 oblong spreading lobes. Stamens 4-6 ; anthers sessile 

 within the throat. Stigma bluntly bifid. Berries globose, 

 crowned by the nearly closed calyx, smooth, 2-celled, 2-seeded. 

 Glabrous shrubs, natives of South America. Leaves on short 

 petioles, oval or ovate, acuminated at the apex. Stipulas broad 

 at the base, and subulate at the apex. Flowers sessile, crowded 

 into heads in the axils of the leaves or tops of the branches. 

 Heads propped by 4 small binately opposite bracteas. This genus 

 differs from Psychotria in the capitate inflorescence, in the 

 smooth berries, and in the number of the floral parts being 

 usually quaternary.

CLXXXI. SALZMA'NNIA (named after M. Salzmann, a 

 collector of plants in Mauritania, and afterwards in Brazil). 

 D. C. prod. 4. p. 617. 



LIN. SYST. Telrandria, Monogynia. Calyx with an oval 

 tube, and a cupular very bluntly 4-toothed or sinuated permanent 

 limb. Corolla with a short tube, and 4 oblong lobes. Alabastra 

 tetragonal. Stamens with very short filaments, and very long 

 anthers. Style 1, undivided, or the lobes are combined. Berry 

 dry, crowned by the limb of the calyx, 1 -celled in the adult 

 state by abortion, compressed, oval, 1-seeded. Seed compres- 

 sed. A glabrous Brazilian shrub. Branches at first tetra- 

 gonal, but terete in the adult state. Stipulas truncate, very

 very short, bearing dense heads composed of 10-12 flowers, 

 girded by 2-4 ovate foliaceous bracteas. Flowers sessile within 

 the bracteas, white. This genus appears to come nearest to 

 Ceph<&lis, from which it differs in the very long anthers, in the 

 compressed fruit, and in habit. 



1 S. NI'TIDA (D. C. prod. 4. p. 617.) Jj . S. Native of Bra- 

 zil, about Bahia on arid hills. Corolla a line and a half long.
