"Rhytidocaulon elegantissimum Hanacek & Ricanek, a new species from Yemen" . "In this paper we describe a new species of Rhytidocaulon known from two localities in the Hadramawt Governorate of Yemen in the Arabian Peninsula. On the basis of our current knowledge, we suggest that the wider surroundings of the Ras Huweira settlement in the Hadramawt Governorate is a centre of Rhytidocaulon diversity in the southern part of the Arabian peninsula. R. elegantissimum differs from R. ciliatum mainly by the longer pedicel, the larger, pale green flowers with more slender corolla lobes and more obviously pentagonal corona." . . . .
