A P. Timoutou Aubl., foliis haud obovatis, fere omnibus alternis, racemis magis 
comosis, petalis superioribus acutis nec rotundatis, crista haud laciniata valde 
differt; ad eam accedit alis acutis, sepalisque, racemis longis, cylindricis. 
Radix perpendicularis, fusiformis simplex vel ramosa, lutea, 1-1,5 mm. crassa, 
5 cm. longa. Caulis unicus, simplex vel ramosus, distincte alatus, alis eis in 
P. Timoutou haud dissimilibus, sæpe superne corymbose ramosus, vel à basi 
ramosus, 20-35 cm. altus. Folia inferiora sæpe verticillata vel etiam omnia alterna, 
ovato-lanceolata, acuminata, leviter petiolata vel subsessilia, pellucide punctata, 
numerosa, 15-20 mm. longa, 5-8 mm. lata, vel in ramis minora. Racemi juven- 
tute, bracteis 3 mm. prominentibus, filiformibus, longe comosi, subconici, dein 
elongati, cylindrici apice tantum comosi, 4-7 cm. longi, 40 mm. lati, densiflori, 
compacti, pedunculati. Sepala exteriora ovato-lanceolata, cuspidata, inæqualia.
