tomentulosi ovatis obtusissimis tubo dimidio brevloribus, fructiferis 

 auctis patentibus ; coi'olla pubescente calyce duplo longiore. — Branches 

 of the style often unequal, the upper one being smaller, as in the pre- 

 ceding. 



Phtllostegia haplostachta (sp. nov.) : cano-tomentosa ; foliis 

 cordato-oblongis seu cordato-lanceolatis crenatis ; verticillastris bifloris ; 

 floribus subsessilibus in spicam simplicem virgatam digestis ; calycis 

 dentibus lato subulatis erectis tubo 3 - 4-plo brevioribus ; corolla? tubo 

 longe exserto, lobis crispis. — Maui, on the sands of the low isthmus. 

 Also gathered by Remy on Hawaii. Calyx 3 or 4 lines long, cylin- 

 draceous, a little curved, and the flower horizontally spreading in 

 anthesis. Corolla white ; the tube 8 or 9 lines long, the lips less 

 unequal than in other species, the upper one and the three lobes of the 

 lower lip rotund and with strongly undulate-crisped margins. Style of 

 the genus. So of the fruit, which is apparently drupaceous when fresh, 

 but is included in the ovoid and nearly closed fructiferous calyx. 



Var. /3. LEPTOSTACHTA : foliis angustioribus e basi minus cordata, 

 pagina superiore calycibusque minutim tomentulosis nee incanis ; flori- 

 bus inferioribus dissitis. — On barren ridges of Kauai ; in flower. 



Phtllostegia truncata (sp. nov.) : tomentulosa; foliis lanceolatis 

 crenulatis basi truncatis vel subcordatis subtus incanis ; verticillastris 

 bifloris ; floribus in spicam simplicem digestis brevissime pedicellatis, 

 infimis dissitis ; calyce puberulo glanduloso repando-truncato, dentibus 

 brevissimis latis obtusissimis ; corollEe tubo elongato, lobis rotundatis 

 subajqualibus crispis. — Maui, Coll. Remy, no. 395. Closely related to 

 the preceding. The two would be taken for the type of a distinct 

 genus ; but I find no sufficient reason for their separation. 



Phtllostegia floribunda (Benth.) : villoso-hirsuta ; caule rigido 

 (bipedali) ; foliis ellipticis seu oblongo-ovatis acuminatis crenato-serratis 

 basi rotundatis vel obtusis ; racemis brevibus plurifloris ex axillis fol. 

 inf., rhachi pedicellis filiformibus calycibusque patenti-hirsutissimis ; lo- 

 bis calycis linearibus tubo suo et coroll^e "late violaceaB" subeequilongis. 

 — Hawaii, in woods of the district of Puna. Before known only from 

 the specimen gathered (probably on Hawaii) by Nelson in Cook's last 

 voyage, and preserved in the Banksian herbarium. Achenia fleshy, 

 projecting from the open mouth of the fructiferous calyx. 



STENOGYNE, Benth., is the other Labiate genus peculiar to the 

 Sandwich Islands. In all the species the corolla is more or less hairy 

 or downy externally towards its summit, while the lower part of the
