brevi pilosa, subtus sericeo- vel subvelutino-tomentosa, albida vel canescentia, terminale e basi sub- 
cordatâ ovato-oblongum, acuminatum. — Rami floriferi tomento cinereo obducti, aculeis sparsis c 
basi latâ recurvis armati. Folia Lernata, interdum quinatis singulis immixtis, illis ramorum sterilium 
similia. Inflorescentia terminalis composita, ad basin saepe ramis axillaribus longis dense panniculato- 
multifloris lateralibus aucta, praeter illos vulgo aphylla, densa, elongata, apicem versus decrescens; 
rami cum rhachi strictâ appresse tomentosi, aculeati, ceterum erecto-patentes, subglomerato-multi- 
flori; bracteae parvae, ovato-lanceolatae vel ovatae. Flores breviter (fructus paullo longius) pedicellati, 
parvi; sepala ovata, tomentosa, in flore et fructu patentia; petala obovata vel suborbicularia, sepalis 
longiora, alba vel rosea, fugacia; stamina in flore suberecta, stylis breviora; fructus e carpellis numerosis 
(80 — 100) parvis glabris compositi, diam. ca. 1 cm. 
Floret in Peruviâ aprili et majo, in Bolivia julio et augusto.

Rami subangulati, crebre fusco-setosi, aculeis sparsis recurvis vel deflexis basi compressis in- 
structi. Folia longe petiolata, ternata; petioli subcanaliculati, aculeati, crebre setosi, villosi; stipulae 
lanceolatae, acuminatae; foliola elliptica, acuminata, argute serrata, utrinque fere 15— 20-costulata, 
supra glabrata, subtus reticulato-venosa, pubescentia, ferrugineo-tomentosa vel saepius pallide cano- 
virentia. Inflorescentiae erectae oblongae multiflorae ramuli suberecti, setosi, villosi; bracteae lanceo- 
latae vel lineares, acuminatae, externe villosae. Flores paru m conspicui. Calyx villosus, sepalis lanceo- 
latis acuminatis brevioribus quam petala. 
Plantam foliis subtus ferrugineis insignem, qualem Wikström descripsit, nuper nemo colligisse 
videtur. — Fl. a martio ad majum.
