Phyllostegia hirsuta, Benth, Tliis is known only by deflorate 

 specimens of Macrae's collection ; but it is probably of this genus. 



Phyllostegia parviflora (Benth.) : molliter villosula vel pubes- 

 cens ; foliis ovatis seu ovato-oblongis serrato-crenatis basi rotundatis 

 cordatisve ; racemo laxo glanduloso- seu viscoso-villoso ; verticillastris 

 plerumque 6-floris, pedicellis gi'acilibus ; calycis lobis breviter lanceo- 

 latis tubo 3 - 4-plo brevioribus, fructiferis vix ampliatis subpatentibus ; 

 corollae tubo puberulo calyce 2 - 3-plo longiore (semipoUicari). — Under 

 this I combine the following : — 



Var. a. Gaudichaudi (P. parviflora, Benth.) : foliis subtus molliter 

 seu moUissime pubescentibus ; racemis saepe paniculatis ; floribus par- 

 vulis ; corolla gracili ; pedicellis scepius calyce {\\ lin.) multo longiori- 

 bus (3-6 lin.) nunc tantum a^quilongis. 



Var. /3. GLABRIUSCULA {P. macrophylla, Benth., prajsertim pi. 

 Macraii) : foliis cauleque subpubescentibus vel glabratis ; floribus ma- 

 joribus ; pedicellis calyce (2-3 lin.) 2 -3-plo longioribus ; verticillastris 

 interdum 8-floris. 



Var. y. MOLLIS {P. mollis, Benth.) ; undique mollissime velutino- 

 pubescen?, canescens ; pedicellis calyce brevioribus vel subaequalibus ; 

 corolla (4-5 lin.) calyce duplo longiore. 



Phyllostegia stachyoides (sp. nov.) : molliter pubescens ; foliis 

 ovato-lanceolatis acuminatis vix basi subcordatis crenato-serratis ; race- 

 mo denso; verticillastris 10-14-floris; pedicellis calyce brevioribus; 

 lobis calycis glandulosi-puberuli subulato-lanceolatis tubo paullo brevi- 

 oribus ; corollae pubescentis tubo calyce duplo longiore. — Hawaii, in the 

 district of Waimea. Leaves much like tliose of P. racemosa, but 

 tapering to an acute jioint, and scarcely at all cordate. 



Phyllostegia clavata (Benth.) : pubescens vel hirsuta pilis 

 appressis, foliis ovatis seu ovato4anceolatis subacutis basi rotundatis vix 

 subcordatis crenato-serratis; verticillastris 6-14-floris, pedicellis calyce 

 subaequilongis ; lobis calycis strigosi late triangulari-ovatis obtusis tubo 

 triple brevioribus ; corolla strigoso-pubescentis tubo calyce triplo lon- 

 giore ; stylo apice clavato. Variat 1. foliis glabriusculis pedicellis 

 fructiferis 2 -3-plo longioribus, 2. sericeo-villosa, canescens, lobis calycis 

 paullo majoribus. — Style more clavate than usual at its summit, the 

 upper lobe smaller and its stigma often abortive. 



Phyllostegia racemosa (Benth.) : villosula seu tomentoso-pubes- 

 cens ; foliis oblongis ovato-lanceolatisve obtusis basi saspissime cordatis 

 crenatis; verticillastris 8-12-floris; pedicellis brevissimis ; lobis calycis
