A comparative study of Grewia bicolor Juss. and Grewia flava DC

Author: Bartsch, Silke Date: 2000 Grewia bicolor and Gewia flava have been recognized by earlier authors as separate species on the basis of the shape of the leaf base, the number of flower stalks on the peduncle and reticulate venation of the tertiary veins. These two "species" ... Read more
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora

Author: Warren, Ben ; Bakker, Freek ; Bellstedt, Dirk ; Bytebier, Benny ; ClaSZen-Bockhoff, Regine ; Dreyer, Leanne ; Edwards, Dawn ; Forest, Felix ; Galley, Chloe ; Hardy, Christopher ; Linder, H Peter ; Muasya, A Muthama ; Mummenhoff, Klaus ; Oberlander, Kenneth ; Quint Date: 2011 BACKGROUND: The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at ... Read more c b
Evolution of floral morphology in Brunsvigia and Crossyne (Amaryllidaceae)

Author: Raimondo, Domitilla C Date: 1998 Floral morphology and its relationship to pollination syndromes is examined, for the genera Brunsvigia and Crossyne (Amaryllidaceae). These two genera have similar vegetative morphologies and share the same mode of seed dispersal (anemogeochory). ... Read more
The functional, ecological and evolutionary significance of culm structures in the Cape Floristic Region

Author: Yates, Megan J Date: 2011 The Cape Floristic Region lies in the southwestern Cape, South Africa, and is known for its high species richness and endemism. This Mediterranean-type climate region receives winter rainfall that averages between 250 and 650 mm annually over ... Read more
A molecular phylogeny of the subfamily Arundinoideae (Poaceae)

Author: Barker, Nigel Paul Date: 1995 The subfamily Arundinoideae has long been considered to be an unnatural assemblage of genera, the relationships of which are obscure or unknown. Because morphological and anatomical data have, to date, been unable to elucidate relationships ... Read more
Optimising regionalisation techniques: identifying centres of endemism in the extraordinarily endemic-rich Cape Floristic Region

Author: Bradshaw, Peter L ; Colville, Jonathan F ; Linder, H Peter Date: 2015 We used a very large dataset (>40% of all species) from the endemic-rich Cape Floristic Region (CFR) to explore the impact of different weighting techniques, coefficients to calculate similarity among the cells, and clustering approaches on ...

The phylogeny of Brachycorythis Lindl. and Neobolusia Schltr

Author: Chuba, David Date: 1999 The monophyly of the genus Brachycorythis has been tested. The phylogeny of the African genera of Orchidinae - Orchideae - Orchidaceae (Schwartzkopffia, Brachycorythis, Neobolusia, Schizochilus, Dracomonticola, Holothrix and Bartholina is ... Read more
Questioning the Cunonia in C. capensis

Author: Kruger, Lynette Date: 1995 All members of Cunonia, excluding C. capensis, occur on the island of New Caledonia. Dickison has repeatedly noted (1973, 1975, 1980, and 1984,) that evolutionary patterns may have led to incorrect systematic conclusions among many cunoniaceous ... Read more
Species limits in the Rhodocoma gigantea (Kunth) Linder complex

Author: Mafa, Paseka Date: 1999 Rhodocoma gigantea and Rhodocoma foliosus have been recognised by earlier authors as separate species on the basis of perianth length and shape. Linder (1985) superficially lumped these two species under Rhodocoma gigantea arguing that the ... Read more
The structure of the perennial growth of Disa uniflora Berg. (Orchidaceae)

Author: Thomas, Janet Clare Date: 1990 The perennation of orchids is poorly understood, in particular that of the Orchidoidae. The understanding of perennation in the Orchidoidae is important because the root-stem tuberoid is used as the one character defining the Orchidoidae as ... Read more
A taxonomic study of the genus Lotononis (DC.) Eckl. & Zeyh. (Fabzceae, Crotalarieae)

Author: Van Wyk, Ben-Erik Date: 1989 The approach and methods used in a taxonomic study of the genus Lotononis (DC.) Eckl. & Zeyh. and related genera of the tribe Crotalarieae (Benth.) Hutch. are briefly introduced in Part 1. Morphological, cytological and chemical data was ... Read more
Variation in Thamnocortus insignis - genetically and environmentally plastic?

Author: Mgidi, Theresa Nobuhle Date: 1999 Environmental variation of Thamnocortus insignis Mast. (Restionaceae) is presented, by using average dry weight measurements of six populations of this species found along the coast of the Cape Province. The dry weight measurements were used ... Read more
