47 O. ? HISPIDA (Roth, nov. spec. p. 95. under Hedyotis) 

 the whole plant is hispid from bristles ; stem ascending, dicho- 

 tomous, terete ; leaves petiolate, ovate-lanceolate ; stipulas se- 

 tosely toothed ; peduncles axillary, bearing few-flowered umbels; 

 corolla twice the length of the calycine lobes. Native of the

 whole plant is roughish from papilla- ; stem straight, filiform, 

 terete ; leaves linear-subulate ; stipulas linear-subulate, a little

 teeth of calyx linear, 4-times shorter than the tube of the 

 corolla. Native of the East Indies. Hedy6tis aspera, Spreng. 

 syst. 1. p. 415. The stamens being inclosed, it is very doubtful

 Hedyotis) plant erect, much branched ; branches rather tetra-

 nov. spec. p. 93. but the Oldenlandia dichotoma of Spreng, now 

 called V&hlia dichotoma, is a very distinct plant. Corolla blue. 

 Anthers inclosed, and therefore it ought to be excluded from the 

 present genus, but it is said to be nearly allied to 0. biflora and 

 0. herbacea.
