 petiolatis crenato-serratis reticulatis nunc rugulosis ; verticillastris ple- 

 rumque 6-floris ; pedicellis calyce brevioribus ; calyce subinaequali, 

 lobis saepius mucronato-acutis vel acutissimis tubura sub^quantibus ; 

 coroUse breviusculoe labio inferiore paullo breviore. — Variat, 1. fere 

 omnino (corolla excepta) glaberrima, laevis, seu pedicellis calycibusque 

 hirsutulis : 2. hirsutula vel hispidula, foliis nunc rugosis asperulis : 

 3. pube brevi molli induta, verticillastris 6 - 10-floris. — Hawaii, 

 brought by most collectors. 



Stenogyne angustifolia (sp. nov.) : glaberrima ; caulibus filifor- 

 mibus sarmentosis saepius procumbentibus ; foliis coriaceis oblongo- 

 linearibus seu lineari-lanceolatis crenulato-serratis basi in petiolum 

 angustatis ; verticillastris bifloris ; floribus fere S. rugosce, lobis calycis 

 inferioribus tubo paullo longioribus ; corolla glabrata. — Hawaii, in the 

 district of Waimea. Possibly an extreme form of the preceding. 



Stenogyne microphylla (Benth.) : glabra, diffuso-ramosissima, 

 subscandens ; foliis parvis (^ - j-poU.) oblongis grosse serratis vel 

 incisis basi in petiolum marginatum angustatis ; verticillastris bifloris ; 

 corolla extus puberula, labio superiore falcato longe producto ; stamini- 

 bus exsertis. — Hawaii. 



Stenogyne crenata (sp. nov.) : hispida, ramosissima, foliosis- 

 sima; foliis parvis oblongis seu ovalibus obtusis grosse crenatis bre- 

 viter (nunc brevissime) petiolatis ; verticillastris bifloris ; corolla extus 

 hispida, labio superiore longiuscule producto ; staminibus exsertis. — 

 Maui, on Mouna Haleakala. Differs from the preceding in the his- 

 pid hairiness, which is retrorse and aculeolate on the acute angles of 

 the stems, in the blunt and crenate leaves, less unequal lips of the 

 corolla, &c. 



Stenogyne diffusa (sp. nov.) : moUiter villoso-pubescens, divari- 

 cato-ramosissima ; foliis parvis rotundis grosse crenatis basi truncatis 

 vel subcordatis (1^ - 2 lin. latis) petiolatis ; verticillastris bifloris ; 

 calycis lobis obtusis ; corolla extus pubescente, labio superiore longe 

 producto ; staminibus exsertis. — Hawaii, in forests of the district of 

 Waimea. 



A specimen of what may be still another species of this small-leaved 

 section was gathered on East Maui, with ovate-subcordate or deltoid 

 leaves, incisely lobed, and with the diffuse branches cinereous-pubes- 

 cent ; but the flowers and fruit are unknown.
