simplices vel dichotomi in racemum terminalem strictum 
unilateralem 3-5-florum abeuntes. Folia pubescentia, ciliata,

Caulis pilis brevissimis hirsutiusculus, superne glaber. Folia 
coriacea, patentia, lineari-lanceolata, longe acuminata, carinata, 
punctulato-scabrida. Flores bini, terminales, ut videtur, 
racemum pauciflorum formantes ; bractew parve lineares 
recurve. Calyx albido-viridis, tubuloso-clavatus basi truncatus, 
striis viridibus per totam longitudinem reticuloso-venosus, 
dentibus lanceolatis recurvis, anguste albo-marginatis. Petala 
Saturate purpurea, unguibus calycem eequantibus glabris, 
lamina obovata bifida, lobis ovatis obtusis, appendicibus binis 
fornicatis ovatis. 
A species founded by Rohrbach on a single fragmentary specimen, and 
for the present doubtfully and tentatively placed in this group: in its 
collective characters appears to be distinct from other species. 
Hab. Proy. of Ouari, in the island of Nippon, Japan.
