?What we know about desmids of Mozambique

Exploration of desmid flora in Moza mbique started in 1898 when Wilhelm Schmidle cite d in his article [1] 15 genera (89 species, 93 varieties and 97 forms) of Desmidiales. Among them Cosmarium abruptum Lund. var. supergranulatum, C. decac hondrum Roy et Biss. var. striatum, C. ellipsoideum Elfg. var. borgei, C. emarginatum West et Wes t var. curtum, C. kilimanense, C. praegrandiforme, C. pseudodecoratum, C. subbalteum, C. subbinale (Nordst.) Lagerh. var. abyssinicum L agerh. f. minor, C. subtriordinatum West et W est var. rotundatum, C. taxichondrum Lund. v ar. ocellatum, C. taxichondrum var. compressum West et West f. maxima, C. wellheimmii, Xa nthidium cristatum Bréb. var. delpontei Roy f. africana, Staurastrum engleri, St. hieronymusii, St. mossambicum, St. quadrifurcatum, St. securiforme, St. subprotractum, Sphaerozosma depres sum (Bréb.) Rabenh. f. rectangula, Onychone ma leave Nordst. f. minima, Hyalotheca recta a nd Phymatodocis irregulare were described as a new for science. Later Prof. G. Evelyn Hutchinson with coauthors [2] noted 5 genera (6/6/6), and Florence Rich [3] published 4 genera (6/6/6). DR. BELA JENÖ CHOLNOKY [4] F OUND 19 SPECIES OF DESMIDS FROM 5 GENERA (21 VARIETIES AND FORMS) AND DESCRI BED AS A NEW FOR SCIENCE FROM MANICA P ROVINCE PENIUM CUCURBITINUM BISS. VA R. AFRICANA, P. JENNERI RALFS VAR. GARUSICUM, EUASTRUM CUNEATUM JENNER F. M AIOR AND COSMARIUM QUADRIMAMILLATUM WEST ET WEST VAR. ANGUSTUM. Finally Prof. Jorge Almeida Rino i n his fundamental works [5, 6] documented 2 3 genera (202/320/328). Pleurotaenium multit aeniatum, Euastrum bombayense (Gonzalves et Gangla) Brandham var. simplex, Eu. oculatu m Börges. var. gronbladii, Micrasterias bourrellyana, Cosmarium askenasyi Schmidle f. undulatum, C. pseudobiremum Boldt var. punctatum Fritsch et Rich f. medioscrobiculatum, Staurastrum petsamoense Järnefelt var. biverticillatum N yygard f. trispinosum, Staurastrum sebaldii Rei nsch var. gracile Messik. f. africanum were described as a new for science, and a few taxa also were recombined. Our original studies of Trans-Zambezia freshwaters added 22 species to the checklist of desmids which encountered now in total 25 genera, 291 species, 344 varieties and 350 forms.
