Szujkó-Lacza, J.: Revision of three Astragalus taxa (Leguminosae) and their cenological relations

species of high mountains and in the Mediterranean area independent from the taxonomical status. The heigth of the Astragalus species decreased from the small shrub to annual species (cf. CHATER 1 .c.) and we suppose that the acaules character of the perennials is young in the evolution process as a consequence of the variability of this character. Astragalus dasyanthus PALL. Syn. : A. eryocephalus W. et K. Plant. Rar. Hung. I. Table 46 (1800) A. pannonicus Schult. (1814) A. Stolzenburgensis In Schur (1853): Über J. Lerchenfeld p. 94. Besides the description of species PALLAS (1778) published a good drawing also from A. dasy­anthus but showing a young plant. PALLAS (1800) In: "Species Astragalorum" the picture is good, except the legumen of species. "Icônes. .." of WALDSTEIN & KITAIBEL (I.e.) was given an exact drawing on Table 46, as A. eriocephalus. In the "Icones. .." of BECK (1903) the drawing is not suitable. (BORBÁS, 1886, described the A. dasyanthus var. monocephalus but according to the Hun­garian text it seems to be an aberration. I could not find it among the herbarium sheets.) The sum total of the investigated morphological characters is 28 (Table 1), out of these four was quantitative ones. The three taxa have 9 similar characters (1, 2, 5, 6, 16, 19, 20, 23 and 25). Astragalus exscapus and A. e. var. caulifer has similarités by the No. 4, 7, 14, 18 and 21. A. exscapus and A. dasyanthus are similar in character No. 12. Between taxa pairs i.e. A. exscapus var. caulifer and A. dasyanthus there are no common characters. The own qualitative character is only one of the A. exscapus, two of the A. e. var. caulifer and 6 of the A. dasyanthus. The seeds of A. exscapus show some nuance of brown colour, less variable from this point of view the A. dasyanthus with its brown seeds, and more variable the A. exscapus var. caulifer because it has seeds from light-yellow to dark lilac, including brown too.
