 able, small, angular, inserted in the placentas, which are spongy, 

 and fixed to the middle dissepiment. Smooth Australian sub- 

 shrubs. Leaves opposite. Stipulas solitary on each side, acute,

 margins ; flowers few, terminal ; capsule beaked at the apex.

 acute, obtuse at the base, on short petioles ; stipulas membra- 

 nous, deciduous, toothed a little on both sides ; cyme thyrsoid,

Cult. None of the species are worth cultivating, except in 

 botanic gardens. They will grow in any light soil ; and will be 

 easily increased by cuttings planted under a hand-glass, or by 

 seed, which latter mode will be preferable. 



LXXXI. ANOTIS (from a priv. owe woe, ous otos, an ear ; 

 there are no accessory teeth to the calyx). D. C. prod. 4. p. 431. 

 Hedyotis species, Ruiz et Pav. and Cav. Houstonia species, 

 Lin. and others. 



LIN. SYST. Tetrdndria, Monogynia. Calyx with an obovate 

 tube, and a 4-toothed limb (f. 96. a.) ; teeth acute, separated 

 by acute recesses, with no accessory ones. Corolla salver-shaped 

 (f. 96. 6,), having the tube a little longer than the lobes ; limb 

 4-cleft ; throat almost glabrous. Anthers inclosed or a little ex- 

 serted (f. 96. c.). Stigma somewhat 2-lobed (f. 96. e.). Cap- 

 sule ovate, crowned by the calyx, 2-celled, with a loculicidal 

 dehiscence at the apex. Seeds 4-8 in each cell, ovate, and rather 

 angular. Subshrubs and herbs, natives of America. Leaves 

 opposite, linear, mucronate or oval. Stipulas undivided or 

 toothed. Flowers terminal, solitary or corymbose. This genus 

 is nearly allied to Rachicdllis, but differs from that genus in the 

 want of accessory teeth to the calyx, whence the generic name. 

 The genus probably contains the types of 3 different genera, 

 which it may hereafter be necessary to separate. 



SECT. I. ERICIOTIS (this name has been given to this sec- 

 tion on account of the plants contained in it having the habit of 

 heaths). D. C. prod. 4. p. 431. Heath-like small shrubs, rarely 

 herbs. Leaves linear, mucronate. Corolla salver-shaped, hav- 

 ing the tube longer than the lobes (f. 96. d.) Tube of calyx almost 

 adnate with the ovarium to the apex.
