Orbán Sándor: Studies on African Calymperaceae, V. Syrrhopodon species by S. Lisowski in tropical Africa

- 82 ­vaginae ad partem mediam dentibus aculeatis longis hyalinis numerosis. Cellulae cancellinarum ad ventrem 8-10 seriatae, rectangulae versus limbidium quadratae vel subquadratae. Cancallina apice rotundata. Lamina lanceolata, limbo laminae polistrato geminatim serrato, marginibus involutis dentatis e medio subtubulosa . Cellulae chlorophyllosae laminae quadratae rectangulares vel hexagonales 9,1x10,1 fj,m, irreguläres, magnae » et acute pluripapillosae . Costa lata, superne et dorso aculeato papillosa, apice dilatato. Propogulae fusiformes, 6-7 septatae. Caetera ignota. Holotypus: "Zaire, Haut Shaba. Env. de Kasumbalesa . Colline Kibwe I. 1400 m. leg. S. Lisowski 1971" (EGR). In appearence similar to Syrrhopodon aculeato-serratus, forming dul l green cushions of 1-2 cm height. Stem near the apex branching, covered by rhisoids. Upper leaves, when dry, are bent or curled, in wet condition straight patent, 3-4 mm long 0,5-0,6 mm broad, their margins strong incurved. The sheating part is scarcely broader than the lower part of lamina, obovate occupies 1/5 of the whole leaf length and bordered by 4-6 cells of broad, unistratose limbidium. The margin of the sheating part is armed by upward directed, acute teeth. Tha blade is ligulate-lanceolate, with short, mucronate apex, bordered by pluristratose margin. The border has double teeth becoming denser near apex. Chlorocysts small, rounded 4-6 angular, 9,1x10,1 >tm ornated by 1-2 large branched apiculata papillae on each side. Midrib vigorous, at base 73,7 m, near apex 52,6 /am, dorsaily V and ventrally covered by spinose papillae. The cancallinae are arranged in 8-10 rows on each side of midrib quadrate or rectangular, shorter near the margin. Sporophyte unknown. Vegetative reproduction by clubshaped propagulae, which develop on the upper third of the midrid and leaf blade, forming small groups. The propagulae are 102,6 Um long, divided into 6-7 i / septae, similar to the propagulae of Syrrhopodon insularum. The S. lisowskii is a corticolous species, which grows in submontane rain forest. Observations: Syrrhopodon lisowskii differs in several aspects from the other species of Section Syrrhopodon. The most conspicuous feature are the strong incruved margin, the spinose midrib and the clubshaped propagulae, which develop on the upper third of the leaf blade.
