Planta haec pluribus notis ad R. Duriaeanam accedit, sed radice lignosa, partibus 
omnibus papilloso-hirtellis (nec glaberrimis), pedicellis longioribus (se. racemo multo 
latiore), petalorum forma et ovarii indumento diversa.

Descriptio: 
Radix annua v. biennis, parvula, superne multiceps. — Caules pumili (in spe- 
ciminulo unico quod coram habeo) 10—15°" longi, adscendenti-erecti, simplices v. 
ima basi ramosi, subtereles v. decursu foliorum obiter striato-angulosi, glaberrimi, 
parce foliosi, superne in axillis foliorum ramulos steriles abbreviatos gerentes. — 
Folia subearnosula, glauca, glaberrima v. margine interdum minute et parce papil- 
loso-asperula, inferiora integra, 2—3°" longa, basi longe attenuata, spathulata, ro- 
tundato-obtusa, caulina basi brevius angustata, cire. 2° longa, usque ad medium 
ternato-incisa, laciniae laterales rhombeo-lanceolatae subacutae quam terminalis obo- 
vata suboblusa paulo breviores; superiorum laciniae omnes acuminatae. — Flores 
albi, magnitudine eorum R. odoratae, primum dense ovoideo-racemosi, dein laxiores ; 
racemus fructiferus (junior) fere dimidium caulem aequans. - Bracteae lineari- 
subulatae, glabrae, cire. 3°” longae, pedicellis florigeris sesqui v. duplo breviores, 
albido-hyalinae, sub fructu deciduae. — Pedicelli tenues, subflexuosi, erecti v. 
erecto-patuli, sulcato-angulosi, in angulis dense sed minute papilloso-asperuli, flori- 
geri 4—5"" aequantes, fructigeri paulo longiores. — Calyx hexasepalus, sepala per- 
sistentia subaequalia, cire. 3°" longa, obovato-oblonga v. ovato-oblonga, glabra, 
v. dorso griseo-papillosula. — Petala alba, 3—31,"" longa, superiorum lamina ap-
