1978 1(3) 77-85 Harald Riedl Heinrich Wilhelm Schott as a developmental morphologist (Buy)
ABSTRACT: Heinrich Wilhelm Schott is well known as the first important monographer of the family of Araceae who also had proposed a great number of generic names still in use in this family. In numerous publications ranging from short notes covering less than one page to magnificently illustrated volumes in quarto and the voluminous Prodromus systematis Aroidearum he contributed more to our knowledge of aroids than any other botanist with perhaps the exception of A. Engler.

1980 3(1) 19-23 Harald Riedl On two aroids described in Russell's Natural History of Aleppo (1794) (Buy)
ABSTRACT: Biarum syriacum (Sprengel) H. Riedl. comb.n. and Eminium intortum (Banks et Soland.) O. Ktze. are discussed.

1980 3(1) 25-31 Harald Riedl Tentative keys for the identification of species in Biarum and Eminium (Buy)
ABSTRACT: The following keys have been prepared for purely practical pur: poses during a visit to the herbarium of Kew Gardens in 1978. They are based on the collections I found there, and on relevant literature published since Engler's 1920 monograph.

1980 3(2) 49-54 Harald Riedl The importance of ecology for generic and specific differentiation in the Araceae-Aroideae (Buy)
ABSTRACT: It is Meusel's (1951) merit to have pointed out the significance of growth-habit for interpreting the evolution of a particular group of plants. In his paper he chose Araceae and Lemnaceae as striking examples to prove his point. While it is rather difficult to translate the German terminology he used for those plants which produce persistent parts above the ground, the term "geophytes" fits well for all those which persist with their subterranean parts alone. Among Araceae, rhizomatous and tuberous geophytes are known. Subfamily Aroideae is composed almost entirely of members of the latter group with the exception of plants growing in water or at least swampy ground, like Lagenandra. While, according to Meusel, intermediates between rhizomatous and tuberous geophytes are found in Colocasioideae, geophytes are rare or absent in the rest of the family.
