 tissima petiolo brevissimo ; stipulce obsolet*. Flores inter minores

A much more delicate plant than the allied M. coccinea, with its 

 small lanceolate leaves, 2-5-5 cm. X 1-1 '7 cm., on j^etioles rarely 

 longer than 2 or 3 mm. The rather showy corolla, with tube 

 1*2 cm. long, and wide round lobes 5 mm. in diameter, is a critical 

 feature. Vediceh 1-2 cm., or longer. Flowering ovary 2'7 mm. 

 deep ; calyx-\o\)&%, to 3 mm. Capsule about 6 mm. in diameter. 



7-1. M. orbifera, sp. nov. 



Frutex scandens glaber caiile filiformi. Folia majuscula tenuiter 

 membranacea ovata acuminata acutissima basi nonnunquam inaqualia 

 petiolata ; stipulce ad vaginam brevissimam reductte arcuatim trun- 

 catam, in novitate nonnunquam glanduloso-fimbriatam. Flores 

 majusculi singuli in axillis dispositi siepius longe pedicellati. Calyx 

 longe infra medium in laciniis 5-8 lineari-lanceolatis acuminatis 

 acutissimis elongatis glaberrimis divisus. Corollce hypocraterifoi'mis 

 tubus latus extus glaber intus in ore dense pilis barbatus erectis, lobi 

 ampli orbiculares vix acuminati subacuti, tubi dimidium excedentes.

 Kevv. 



Distinct in the large orbiculai- corolla-lobes, giving the upjter part 

 of the bud a bulbous appearance. Leaves 4-7 cm. x 2-3 cm., with 

 petiole upwards of 1 cm. Pedicels to about 2 cm. CV//y.r-lobcs 

 6 mm. or longer. Corolla-iviiM I'o cm. nearly, the average width 

 4 mm. : lobes 8 mm. long and wide. 



This species, as the tubular base of the calyx indicates, is allied to 

 M. coccinea, which it seems to connect with M. hispiJa. The llowcr 

 suggests also certain species — M. iiijlata, for instance — of the second 

 main group (§ Heterochlora). 



75. M. divaricata, s]). nov. 



Frutex glaberrnnus caule complanato sulcato. Folia mediocra 

 papyracea ovato-elliptica apice acuminata acuta, basi acuta petiolo 

 longiusculo gracillimo ; stipulce \\w\ dociduie brevissime vaginantes. 

 Flores in cymulis ramulis perpendicularibus disj)ositi notabile divari- 

 catis alaribus, pedunculo validiuseulo pedicellis suba-quante longius- 

 culis ; pedicellus leniter glaberrimuiu in ovarium angustatus co.stu- 

 latum, hructeis bracteolisque setacete exigua;. Calyx basi tubularis 

 disco adnatus, lobis 4 parvis carneis crassis ovatis acuminatis acutis
