Plunta perennis, csespitosa. Radix longa, ramosa, flava, collo bipollicari 

 foliorum emarcidorum basibus fuscis obtecto. Caules plures, assurgentes, 

 filiformes, purpurascentes, 1 — 3-flori, palmares v. spithaincei, nunc pe- 

 dales, filo emporetico vix crassiores. Folia radicalia plurima, conferta, 

 erecto-patentia, lanceolata, obtusa, coriacea, glabra, viridia, subtus ob- 

 scurfe 3-nervia, margine parum recurvata, infern^ angustata, ima basi 

 tamen dilatato-membranacea, 4 — 5-uncialia, seniipollicem circiter lata; 

 caulina recurvato-patentia, linearia, obtusa, margine recurva, sesquiun- 

 cialia, basi in vaginam unguicularem connata. Calyx tubulosus, 5-den- 

 tatus, interstitiis nienibranaceis : dentibus subulatis, erectis, tubum sub- 

 aequantibus. Corolla infundibuliformi-campanulata, azurea, calyce duplo 

 longior, sesquipoUicaris, limbo 5-loba ; lobis ovatis, acutis, sinubus pro- 

 minentibus acutis integris. Filamenta canaliculata, basi dilatata. An- 

 theroe oblongae, obtuste, incumbentes, biloculares, flavse. Ovarium fusi- 

 forme, pedicellatum. Stigma bipartitum : laciniis ligulatis. Capsula

This fine species comes very near to P. adscendens, which is chiefly distin- 

 guished by its acute leaves, more numerous flowers, thrice shorter calycine 

 teeth, and by the blunt lobes of the corolla. Its root, which is intensely 

 bitter, is used as a tonic and febrifuge by the natives. This genus is princi- 

 pally distinguished from Gentiana, as now limited, by its deeply-parted stigma, 

 winged seeds, and by the presence of accessory appendages alternating with the 

 lobes of the corolla. 



2. P. depressa, subcaulis, csespitosa, uniflora, surculosa ; dentibus calycinis 

 ovato-lanceolatis mucronatis, corolla campanulata : lobis integerrimis 

 aristatis, foliis lanceolatis mucronatis margine scabris; surculinis obo- 

 vatis.
