 Title    Verbreitung von Iridoiden in der Gattung Verbena und einigen anderen Verbenoideae Iridoids in Verbena and Some Other Verbenoideae  
 Abstract    12 species of the genus Verbena and one Citharexylum species have been examined for iridoids. Besides the known compounds verbenaline, hastatoside, griselinoside, lamiide, ipolamiide and brasoside, two new iridoids, pulchelloside I (1) [2] and pulchelloside II (2) [3] have been isolated from Verbena species. The structures and absolute configurations of pulchelloside I and II have been determined by spectroscopical methods and some chemical reactions. Citharexylum solanaceum has been shown to contain lamiide and durantoside I. The distribution of the iridoids is in excel­ lent agreement with the taxonomic treatment of the genus Verbena by Schauer. The taxonomic significance of our data and some data from the literature regarding the classification of the sub­ family Verbenoideae is discussed.

 Title    Accumulation of Photoassimilatory Products by Phycobiliprotein- Containing Algae with Special Reference to Cyanidium caldarium  
 Abstract    Representatives o f phycobiliprotein-containing algae such as Anabaena cylindrica, Anacystis ni-dulans, Gloeotrichia echinulata (Cyanophyceae), Chroomonas spec., H em iselm is rufescens, Rhodo-monas spec. (Cryptophyceae), Porphyridium cruentum, Rhodella violacea (Rhodophyceae) along with the unicellular Cyanidium caldarium (unspecified systematic status) have been investigated for their typical photoassimilatory accumulation products. While the red algal species synthesize a rather specific heteroside, 2-O-D-glycerol-ar-D-galactopyranoside (= floridoside), not encountered in the other species analyzed, blue-green algae accumulate fructose, glucose, and sucrose, while the cryptomonads accumulate only glucose and. to a lesser extent, fructose. Cyanidium synthesizes neither disaccharides, nor a heteroside, but shows rapid 14C-labelling o f fructose and glucose. These results are compared with further biochemical and structural findings and are discussed with emphasis on chemotaxonomic implications. Cyanidium caldarium is proposed as an endocya-nome consisting o f a single endocyanella providing less (apoplastidal algal?) host cell.
