 " SufErutex volubilis tenuis subramosus. Flores albi." 



24. M. pichinclieiisis, sp. nov. 



Frutex volubilis, caule valde complanato angulato-sulcato, primo 

 dense pubescente, tardius glabrescente, cortice dilute induto brunneo 

 plus minus annulatira excorticante. Folia inter minora subcoriacea 

 margine valde revoluta, venis omnino occlusis, triangulari-lanceolata 

 acuminata acutlssima, basi latissime truncata ssepius cordata, petiolo 

 valido dense pubescente brevissimo, supra glabra necnon aspera sub- 

 nitentia in siceitate nigrescentia, subtus valde discoloria densissime 

 incano-tomentella ; stipulcB triangulares acuminatse acutse, vix primo 

 vaginantes, tandem circum nodo cupulam sublignosam formantes 

 tumidiusculam. Flores parvi singuli v. pauci in axillis gracilibus in 

 pedicellis oriundi hirtellis. Cali/cis lobi anguste lanceolati crassiuscuh 

 rigidi acutissimi longiusculi, ovario sulcato hii'tello. Corolla inter 

 minimas hypocrateriformis extus glaberrima, lobis oblongis obtuslssi- 

 mis suberectis, ore dense barbata. Capsula parva pyriformis extus 

 minute puberula. 



Ecuador. Mt. Picbincha, 10,000 to 12,000 ft., Conthouy\ 

 Fraserl Jameson 56! 152! 287! Lehmann 495! At 13,000ft., 

 Hall 80 ! 



Allied to M. pubescens, but readily distinguished by the truncate 

 or cordate leaf -base. Leaves l'5-2 cm. x 4-9 mm. broad at the base, 

 which is the broadest part ; stijjule 5 mm. x 3 mm., on an average. 

 C'al//jr-\ohes 2-3 mm. long. Corolla-tuhe 5-6 mm. long, lobes 

 2-2'5 mm. Capsule 5-6 mm. long, 4 mm. wide. 



25. M. EVENIA Sprague, in Bull. Herb. Boiss. ii. v. 835 (1905). 

 Ecuador. In valle Lloense, 8000 ft. Fl. Aug.-Sept., Jameson 



352 ! Pichincha, 12,000 ft., Jameson 74 ! In herb. Kew. 



Ileadily distinguished by the apparently veinless condition of the 

 leaves, and the truncate stipules. 



26. M. corticifer, sp. nov. 



Frutex volubilis, ipsis in novissimis glaberrimus, caule in juventute 

 filiformi mox tamen cortice dilute flavo nitente induto subannulato. 

 Folia parva crassiuscula evenia lanceolata acuminata, basi acuta 

 petiolo brevi ; stipiilce truncatae nee apiculatse. Flores minimi inter 

 folia passim nunc in cyniulis nunc racemulis sa-pius plus minus sub- 

 umbellatim dispositi, pcdunculis sicpius validiusculis, nunquam tamen 

 fasciculati, inter minimos. Calycis dentes parvi subulato-lanceolati. 

 CorollcB tubus pinguiusculus necnon tamen brevis insuper parum 

 ampliatus, lobi parvi obtusi intus pubescentes. Capsula parva pyri- 

 formis vix costulata glabra Isevis. 



Colombia. Pasto, 8800 ft., ex parte Triana 1795 ! In herb. 

 Mus. Brit. 



Allied to Sprague's M. evenia, but distinct in the nan*ow leaves 

 with flat margins, the glabrous ovary, etc. Leaves 2-4 cm. x 5- 

 13 mm. ; petiole 3'5 mm. Cft/y.r-teeth barely 1*5 mm. long. Corolla
