34 THE GENUS MANETTIA 



Schumann {loc. cit.) treats this and the two followhig species as 

 a single species of four varieties ; but they seem to me to be quite 

 distinct, and readily separable by the vegetative characters alone — 

 especially the leaf-venation and the indumentum of the young parts 

 (see next species). Bentham {loc. cit. supra) has fallen into similar 

 error, associating Regnell's plant with Spruce's no. 5740, which is 

 M. congestoides {vide infra). The true M. congesta has a well- 

 marked reticulum between the main lateral leaf- veins ; and the youngest 

 parts of the stem and young leaves are villous-pubescent, but not 

 clothed with arachnoid or pulverulent indumentum. 



54. M. congestoides, sp. nov. 



Frutex scandens caulibus gracilibus Isevibus sulcato-complanatis, 

 novitatibus pulverulentibus subarachnoideis mox glabrescentibus. 

 Folia plana membranacea lanceolato-elliptica utrinque acuminata 

 acutissima, demum glabra ; vence primariai laterales tenuissima? paucse 

 (utrinque 4-5) distantes ; petiolo gTacili pro rata longiusculo ; 

 stipulce breviter insuj^er deltoideo-apiculatse basi vaginantes. Flores 

 hypocrateriformes inter minimos plurimi in pedicellis longiusculis 

 glabrescentibus in axilli* fasciculati ebracteolatis. Calyx ad basin in 

 laciniis ovato-oblongis rcHexis acutis glabratis majusculis divisus. 

 Corollce tubus angustus cylindricus vix elongatus extus sparse pube- 

 rulus, lobi rotundati subreHexi nee barbati. Capsula parva sub- 

 globosa glabrata Isevis nee costulata.

Readily identified by the glabrate leaves, the absence of any 

 apparent rete between the primary leaf-veins, and the arachnoid- 

 pulverulent indumentum upon the youngest parts of the stem antl 

 the young leaves. Leaves 4-8 cm. X l"5-2'5 cm., with petiole 

 4-8 mm. long. Pedicels as much as 1 cm. long. Calyx-\ohQ% 

 2x 1"5 mm. Corolla-in\>Q 6 mm. long, limb 3 mm. in diameter. 



55. M. verticillata, sp. nov. 



Frutex scandens caule pro genere validiusculo in novitate dense 

 flavo-subtomentoso demum pubescente sulcato stfiato. Folia inter 

 majora papyracea jjlana ovata v. lanceolata apice acuminata acuta 

 basi acutiuscula, petiolo longiusculo dense hirtello, sujDra asperulo- 

 hirta subtus velutino-tomentosa ; vencd primarise laterales subtus 

 manlfestae utrinque 6-8 ; stipulce basi breviter necnon late vaginantes 

 insuper notabiliter apiculatse. Flores minimi ad nodos plurimi globi- 

 forme fasciculati, pedicellis tenuibus tardius elongatis dense flavo- 

 hirtellis. Calycis lobi pro rata majusculi lanceolati plani pilosissimi. 

 Corolla h3'^pocrateriformis lobis prsesertim versus apicem pilosis. 

 Capsula anguste oblanceolata extus pubescens, lobis cal^'cinis persis- 

 tentibus conspicuis coronata nee magna, basi in pedicellum leniter 

 insensim contracta.
