OLDENLANDIA CORYMBOSA 141 



Naylor extracted another principle which he found combined 

 with the alkaloid in a soda precipitate of the latter ; it is a 

 product of the decomposition of a glucose, the formula of which 

 is C 2 _H 49 O 7 . This compound remains insoluble when the alka- 

 loid is treated with ether. Repeated boiling in alcohol renders 

 it colorless. It is bitter, soluble in alcohol and dilute acids ; 

 insoluble in ether and chloroform. Reaction, neutral. 



BOTANICAL DESCRIPTION. A large tree, with leaves oppo- 

 site, oval, entire, acute, downy. Petioles long, flat above, with 

 2 stipules. Flowers axillary, in compound verticillate racemes. 

 Calyx adherent, with 5 promptly deciduous teeth which leave 

 a scar that also disappears. Corolla much longer than the calyx, 

 funnel-form, the limb 5-cleft. Stamens 5, inserted near the 

 middle of the tube. Filaments rudimentary. Anthers 2- 

 celled. Style longer than the corolla. Stigma globose. Seed- 

 vessel rather rough, ovoid, flattened, of 2 compartments, where 

 are inserted numerous seeds, imbricated, circular, encircled by 

 an entire wing. 



HABITAT. Angat and the woods of San Mateo. Blooms 

 in August. (P. Blanco states further that this tree grows to a 

 height of about 3 yards in Angat and that it exhales a strong 

 odor resembling that of vinegar at times, and again like that of 

 tobacco.)

USES. The Sanscrit writers often mention this plant as an 

 important remedy for the fevers due, according to their theo- 

 ries, to disordered bile, i. e., remittent fevers, accompanied by 

 gastric irritability and nervous depression. The entire plant is 

 used to make a decoction, often combined with aromatics. 

 Dymock observed in Goa that this plant could be gotten in all 

 the shops of the herb-venders, and that it was widely used as
