Pindus Tymphaeus: in summi montis Zigós supra Metzovó regioné silvatica, alt. 4500 — 5000', substratu siliceo-serpentino. Legit Dr. TH. DE HELDREICH, 19-20 Jul. 1885. Schedula DOMINÍ: Koeleria grandiflora BERTOL. DOMIN (BP); Kajabasa. 5 Juli. 1886, Formanek. Manuscr. Domini: Koel. grandiflora var. pyra­midata (duplicatum, Herbarium K. DOMIN) (PRC). Description of the leaf-epiderm: On the abaxial and axial sides of the innovation­al leaves the cells are large, the cellular walls strongly sinuous and densely, incras­sately pitted. In the senile leaves, the costal zone is 2—4-seriate, the parenchymatous cells sporadically alternating with silica-bodies or here and there with an initial hair. Silica-bodies cubic or cubicoid, their walls strongly sinuous. Intercostal zone 4—6-seriate, with sporadic small macro-hairs and some large macro-hairs, present as mere vestiges. One or two rows with stomata. Costal zone of juvenile leaves 3—6­seriate, silica-bodies regularly alternating with parenchymatous cells, elongately oblong, longitudinal walls strongly sinuous, transversal walls straight; rarely with vestiges of hairs. Intercostal zone 4—5-seriate, the elongated parenchymatous cells alternating with small macro-hairs; stomata in 2 or 3 rows, immersed. Cellular walls rugulose (Plate VI, Figs. 2,3). The definitely robust plant is densely cespitose, the innovation strong, the rhizom­atic system also compact. The plant is 47 cm high, its culm strong. The senile blades of the basal leaves are about 17 cm long and 3 mm wide, flat, marginally with a strong, rough rib. The blades are green or slightly greyish, the vaginae whole. The juvenile leaves may attain 22 cm, they are 2 mm wide, flat or convoluted, basally and on the undersides hirsutely margined due to infrequent pili; the vagina is about 4 cm long, subglabrous. The developed culm is foliose up to about half of its length. The uppermost blades are 5—6 cm long and even longer at lower points, the sheaths 12 cm long, the leaves 2.5 mm wide, ribbed, acute. Ligula well developed, 0.8 mm long, rotundate, entire. The culm of the Kajabasa and Valamare specimens are smaller, the holotype reaches 38 cm. The panicle of the holotype is elongately cylindrical, tapering apicad, that of the other two exemplars compact, cylindrical, stramineous, with some brownish hue. Glumae sericeous, dorsally rough, inferior glume 6 mm, superior one 7.2 mm long, acute; lemmae narrow, 6.2 mm long, acute, surface pubescent due to very short hairs; paleae 5.4 mm long, hyaline, bilobate. Antherae 2.8 mm long. The three members of the Series indubitably exhibit another evolutional line. The diploid, tetraploid, and hexaploid grade plants display, similarly to the series discussed in my earlier papers, similarities and differences of the same character as the other series of the genus. By the clarification of this series, I was able to clear simultane-
