Preliminary study about an endangered wild Brassica population in Albania

摘要

According to the Flora of Albania, there are existing two wild Brassica species in the Southern coast of Albania, B. incana TEN. and B. oleracea L. (PAPARISTO et al. 1988, pp. 368-369). The biennial (!) B. incana is only known from Himara, near to theIonian Sea while the wild bi- or perennial B. oleracea is distributed through the coastal rocks from Vlore up to Sarande (see the map). The authors of the Flora differentiate the two species by presence or absence of hairs, the more or less woody basisof the stem and some fruit characters which are known to be very variable. B. oleracea, of course, occurs in cultivation also. In the elder Flora of Albania by DEMIRI (1983, p. 220), both species are differentiated as follows: B. oleracea: leaves glabrous or sparsely hairy, up to 1.20m tall, cultivated. B. incana: basal leaves with hairs, upper part of the plantglabrous, about 1.00m tall, perennial, wild.
