v <il (type, in hb. Gray). // Four species of Rinorea or Alsodeia are now 

 definitely known from north of Panama. One of them, the Mexican 

 plant described by Watson as Alsodeia parvifolia, is of very doubtful 

 generic affinity. The other old species are Rinorea sihatica (Seem.) 

 ( ). K. and Rinorea guatemalensis ( Wats. ) Bartlett, n. comb. 1 . 1 lsod\ ia 

 guatemalensis Wats., Proc. Am. Acad. xxi. 458). Points which distin- 

 guish R. deflexiflora from the former are that in II. silvatica the 

 spikes are nodding, the flowers are nearly sessile, and the sepals are 

 almost as Long as the petals. In /<'. guatemalensis the leaves are 

 broadest at the middle and are acute at the base, as contrasted with 

 the more cuneate, subcordate Leaves "l B. deflexiflora.
