NATURAL HISTORY OF PLANTS. 



flowers ' are collected in a terminal false capitule of glomerules or 

 cymes with very short pedicels, the whole accompanied with two 

 pairs of rather large decussate bracts forming an involucre (fig. 263). 

 Little consistent as are the stems of the preceding plant, there are 

 congeners from nearly the same countries with still softer stems.

They are creeping herbs implanting themselves in the soil by their 

 adventitious roots. Aublet named some Tapogomea^ and ranged 

 others in the great genus Psychotria of Linn.s;us.^ More recently the 

 name Qeopliila* has been given to the creeping and rooting herbaceous 

 species of Psychotria ; they are abundant in all the tropical regions of 

 both worlds. 



The woody Uragogas, also abundant in the same regions, especially 

 the tropical, vary: 1. in the position of their inflorescences, which 

 may be axillary,' instead of terminal, pedunculate or sessile, and may
