A fungus associated with the leaf spot of German iris (Iris germanica) was identified as Cladosporium iridis based on the morphological characteristics of the condiophores and conidia. A conidial suspension of the fungus was artificially inoculated onto a healthy unwounded plant, proving its pathogenicity. This is the first record of this disease from Korea.

Several unusual fatty acids including myristic acid (14 : 0) and lauric acid (12 : 0) were investigated in the Iris family and other related plants. Especially the roots of Iris tecorum contained 75.9% myristic acid in total fatty acid contents and that of Iris germanica contained 57% myristic and 15.5% lauric acid (12 : 0) whereas 10.7% lauric acid and 9.5% capric acid (10 : 0) were detected in the roots of iris ensata as compared to the total fatty acid contents. The total fatty acid contents in the seeds of Foeniculi fructus and Torilis japonica was relatively higher 193.3 mg/g dry wt and 128.2 mg/g dry wt, respectively. 64.5% linoleic acid (18 : 2) and 48.9% ${\alpha}-linolenic$ acid (18 : 3) were observed in the seeds and leaves of iris tectorum whereas its lateral roots contained 9.5% caprylic acid (8 : 0) and 8.6% capric acid. The percentage of myristic acid of the total fatty acid in the immature seeds of iris tectorum and Iris germanica was 10.8% and 15.6%, respectively.
