majora persistentia, obovato- v. rotundato-elliptica, venulis divergentibus. Petala lateralia carina cristata 
breviora, margine interiore obscure lobata, Capsula emarginata, ciliolata. Semina hirta. 
Hab. Unyoro, Col. Grant ! 
A curious form of the species, which in the * Flora of Tropical Africa? I included under P. arenaria, 
Willd., but, I think, incorrectly. It is connected with the usual state of P. persicariefolia, DC., which 
was gathered by Col. Grant in Unyoro, common on cultivated ground, by a specimen brought home by 
the same gentleman from Ukidi, in which the leaves are more nearly linear and the racemes supplemented 
by small fascicles of flowers in the upper axils, in this respect approaching P. hypericoides, Webb, Frag. 
Fl. Æthiop. 81, which I have reduced to P. persicariefolia. 1 doubt if the true Р. arenaria has been 
found in Eastern Africa. For the synonymy of P. persicariefolia, DC., see Fl. Trop. Afr. i. 129. 
[In moist places, and by cultivation, on the plateaux at 2?-3? N. lat. This species includes the Poly- 
gale nos. 1 and 2 of Speke's Appendix.—J. A. G.]

strophiolatis. 
Frutex strictus, glaber; rami crassitie pennæ cygni, ramulis fastigiatis rigidis foliosis. Folia acicularia 
mucronata, sepe fasciculata, 3-13 poll. longa. Racemi terminales, breves, folia sæpius paullo excedentes, 
rachide compressa cicatricibus dentiformibus florum delapsorum notata. Bractee minute, rigidæ, acute, 
caducissimze. Pedicelli brevissimi sepalis exterioribus breviores. Sepala anteriora connata, posteriora 
elliptica persistentia, lateralia (ale) cæteris 3—4-plo longiora, elliptica, obtusa, cum petalis decidua. 
Carina dorso cristata. Stamina 8 monadelpha, 2 centralia ananthera, filamentis pilosis. Capsula com- 
pressa, elliptica, bidentata v. emarginata, 1 poll. longa. Semina sericeo-pilosa, strophiolo cordato albo 
coronata. 
Hab. Bare ground, Madi, Col. Grant ! 
А very remarkable plant, of which but one specimen, a very good one, was brought«home. We have 
specimens of the same, or a close ally, sent home by Mr. Barter from Nigritania.
