PRODROMUS FLORiE NOVO-GRANATENSIS. 295 



ramis sœpeexpansis. Caulis tetragonus, pleurotropus, clorso con- 

 vexus vel planus, facie minus profunde trisulcatus. Folia inferne 

 longe remota, nec non superne et in ramulis parum' distantia, 

 opaca, subtuspaulo pallidiora et vix nitentia ; lateralia «antica» 

 (potius exacte lateralia), sub angulo fere recto patentia vel (in 

 caule primario) parum retrorsum directa, 4-5 millim. longa, 

 1 1/2-2 1/2 millim. lata, oblonga, inferiora latiora et evidentius 

 inaequilatera, superiora angustiora, margine superiore versus 

 basin dilatata, usque ad médium remote denticulata, margine 

 iuferiore integerrima et revoluta, obtusa vel acutiuscula, prope 

 apicem minute et confertius denticulata, basi superiore adnata 

 (nec auriculata), inferiore paululum excisa etrotundata, supra 

 convexiuscula, nervo (prsesertim versus apicem folii) prominente. 

 Folia axillaria lateralibus paulo breviora, sed non angustiora, 

 ovata, subsequilatera, exauriculata. Folia intermedia inferne 

 duplo, superne triplo-quadruplo minora, obovata, margine in- 

 teriore remote denticulata, exteriore subintegerrima, apice in 

 aristam lamina breviorem incurvam subinlegerrimam attenuata, 

 dorso versus apicem subcarinata, basi biauriculata, auriculis 

 dilatatis rotundatis, exteriore plerumque majore, interiore non- 

 nunquam denticulis nonnullis instructa. Spicse ramulis breviori- 

 bus (supremis brevissimis) insidentes, brèves. Bracteae ovato- 

 triangulares, sensim acurninatae, obtuse carinatœ, serrulatâe. 

 Macrosporse (in var. peruviana tantum observatee) 0,85-0,90 

 millim. crassse, albidse, demum fusco-cinerascentes, angustius 

 elevato-reticulatae. Microsporœ fuscescentes, 0,03 millim. crassse, 

 dense muriculatee. 



In Andibus Quitensibus (Jameson in h. Boiss.); ad montem Pichincha 

 (Jameson sec. Hook. et Grev.}, in suburbanis Quitensibus (Francis Hall. 

 in h. Ber.) ; in Andibus Ecuadorensibus (R. Spruce, ^385, in h. Boiss.) ; 

 prope Tocarema altitudine 2500 metr. (Lindig., n. 1508 ). 



Species, ut videtur, polymorpha. Varietas peruviana (Lechler, PL 

 Peruv. éd. Hohenacker, n° 2015, prope ïabina lecta) differt habitu den- 

 siore, surculis magis adscendentibus, ramis minus expansis, foliis latera- 

 libus toto margine superiore denticulatis , nec non margine interiore 

 remotissime denticulatis basi interiore potius angulatis quam rotundatis, 

 foliis intermediis in cuspidem latiorem vix aristifbrmom abeuntibus,
