 (1889). 



EcuADOE,. Andes : Mt. Guajrapata. Fl. June. Spruce 5438 ! 

 " Suifrutex volubilis tenuis subramosus. Flores albi." 



24. M. pichiucliensis, sp. nov. 



Frutex volubilis, eaule valde complanato angulato-suleato, primo 

 dense pubescente, tardius glabrescente, cortice dilute induto brunneo 

 plus minus annulatini excorticante. Folia inter minora subcoriacea 

 margine valde revoluta, venis omnino occlusis, triangulari-lanceolata 

 acuminata acutissima, basi latissime truncata saepius cordata, petiolo 

 valido dense jDubescente brevissimo, supra glabra necnon aspera sub- 

 nitentia in siccitate nigrescentia, subtus valde discoloria densissime 

 incano-tomentella ; stipulce 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. Calycis lobi anguste lanceolati crassiusculi 

 rigidi acutissimi longiusculi, ovario sulcato hirtello. Corolla inter 

 minimas hj^pocrateriformis extus glaberrima, lobis oblongis obtusissi- 

 mis suberectis, ore dense barbata. Capsula parva p^^riformis extus 

 minute puberula. 



Ecuador. Mt. Pichincha, 10,000 to 12,000 ft, GoutliouyX 

 Fraserl Jameson 5(M 152! 287! Lelimann 495! At 13,000ft., 

 Hall 80 ! 



Allied to M. puhcscens, but readily distinguished by tbe truncate 

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

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

 Crt^y^-lobes 2-3 mm. long. Corolla-iwhQ 5-6 mm. long, lobes 

 2-2*5 mm. Capsule o-ij 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. 



Readily 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 ; stip>ul(s truncatse nee apiculatse. Flores minimi inter 

 folia passim nunc in cymulis nunc racemulis ssepius plus minus sub- 

 umbellatim dispositi, pedunculis ssepius validiusculis, nunquam tamen 

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

 CorollcB tubus pinguiusculus necnon tamen brevis insuper parum 

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

 formis vix costulata glabra Isevis. 



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

 Mus. Brit. 



Allied to Sprague's 31. evenia, but distinct in the narrow leaves 

 with flat margins, the glabrous ovar}^ etc. Leaves 2-4 cm. x 5- 

 13 mm. ; petiole 3 '5 mm. C'«/y^-teeth barely 1"5 mm. long. Corolla 

 4 mm. long. Capsule about 5 mm. long.
