My living plant I have brought from Bulgaria in 1969 has reached this height in my experimental garden at the time of ripening of achenia. The whole plant is densely villous, has a brownish colour or is silvery green. It has a thick, short — 2 to 3 cm long — rhizome out of which grows the later lignifying radix eormiferous. This, in turn, develops upwards blooming, and partly sterile cormi, and downwards adventive roots. At the original location, in the dry and warm ambiance, these horizontal roots bring the cormi in a relatively short time. The horizontal roots of the Achillea bidgarica (DEG. et URUM.) UJH. were several metres long in the loose, fertile soil of my experimental garden developing one cormus at a time. These informed me where does the original plant expands. The caule of the sterile plants is about 5 cm long and 1.8 mm thick with the internodes having a length of about 3 mm. The circumference of the laminae of sterile cormi is an elongated elliptic having a length of about 4 cm and a width of e. 8 mm; the leaves are sessile, the lamina is three- or four-fold parted, the individual laciniae having a width of 0.5 mm with sharp apices and very small cartillages on their ends; the rachis is slightly alated. The blooming cormi are simple, having a length of 25 to 30 cm, and a thickness of 2.5 mm; their lower part is sublignous, and at the top of the eaulis is the corymbus. The complex corymbus has a diameter of about 5 to 6 cm; the eauli of the primary corymbus are 2 cm long and 0.3 mm thick; these are slightly sulcated. The secondary and tertiary eauli are, however, pedunculi bearing the capitula. The lower leaves of the fertile eauli are similar to the sterile ones, the bases of the petioli are more wide, and the stipulae are laciniated; the laminae have a rather cylindrical form, and sometimes the segments of leaves are longer, making, thus, also the circumference more oval shaped. The lamina has a width of 1 to 1.5 cm, the laciniae having deltoid shape, with sharp apices and very small cartillages on their ends. The upper leaves are similar to the lower ones, except that these are shorter, c. 4 cm, and are tripartita; the bracteae of the branches of the corymbus are similar to the leaves of the eauli, but are smaller. The corymbus has a diameter of 5 to 6 cm, the capitulums are cylindrical with a length of 4 mm, and a thickeness of 2 mm. The involuerum leaves of the capitulum are half-imbricated, have a faint yellow colour, are shining, sometimes are covered with hair. These have a length of 3.5 mm, and a width of 1 mm, have blunt apices, the edges are lacerated, and the margins are sometimes ciliolated. The ligulate flowers are yellow, the
