222 FLORA NIGRITIANA. 
2. Polygala nutans, Hook. fil. ; annua, pubescens, caule erecto 
parce ramoso, foliis oppositis patulis subsessilibus linearibus 
v. lineari-lanceolatis obtusis utrinque pilosis, racemis axillari- 
- bus erectis 8-10-floris foliis dimidio brevioribus, floribus im- 
bricatis deflexo-nutantibus, sepalis ext. liberis int. late elliptico- 
ovatis hirsutis eiliatisque capsula pilosa breviter oblonga pro- 
funde emarginata 3 longioribus, carina dorso longe cristata.— 
— Accra, Vogel. 
Caulis gracilis, 6-uncialis, patentim pubescens. Folia uncialia, 
2-4 lin. lata. Racemi 4 unc. longi. Flores albidi v. vi- 
rescentes, 2-3 lin. longi, alis obtusis. 
Also an Abyssinian plant, and closely allied to P. erioptera 
and P. arenaria. The flowers are similar in all, but are not so 
densely imbricated in this as in the latter, from which it further 
differs in the narrower foliage; a variable character however.
