The Cucurbitaceae of Southern Africa
- A. Meeuse
- 18 November 1962
An investigation into the nature of the bitter principles contained in the fruits and other parts of any species of the Cucurbitaceae in connection with the incidence and occurrence of these substances in certain horticultural varieties and their related wild forms.
Bitter principles of the cucurbitaceae. VII.†—the distribution of bitter principles in this plant family
The distribution of the twelve known cucurbitacins in 45 species, belonging to 18 genera, is reported and the relation between bitter principle composition and taxonomic divisions is discussed.
Entomophily in the dioecious gymnosperm Ephedra aphylla forsk. (=E. alte C.A. mey.), with some notes on Ephedra campylopoda C.A. mey. III: Further anthecological studies and relative importance of…
The overall conclusion is that entomophily in some and conceivably in all Ephedra aphylla appears to be the most important pollinators, Hymenoptera taking a second place.
THE POLLINATION ECOLOGY OF ORCHIS GALILAEA (BORNM. ET SCHULZE) SCHLTR. (ORCHIDACEAE)
Orchis galilaea has evolved a pollination mechanism based on a sexual attraction specific for the males of H. marginatus, which is the result of the strong, musk-like scent.
New and Interesting Records of South African Flowering Plants.
Frutex multiramosus, 1-2 m., interdum usque ad 3 m., altus. Rami ramulisque teretes, cortice griseo longitudinaliter pauceque rugoso obtecti; ramuli ulteriores subtereti vel subquadrangulares,…
A NOTE ON THE POLLINATION OF NOCTURNALLY FLOWERING SPECIES OF NYMPHAEA
ANTHECOLOGICAL RELATIONS BETWEEN REPUTEDLY ANEMOPHILOUS FLOWERS AND SYRPHID FLIES
Crop and gut contents analyses revealed that some of these flies feed for some time (almost) exclusively on the pollen of the Sea Club-Rush, but there is as yet no conclusive evidence that Lejops (or any other syrphid for that matter) is an effective pollinator of this plant species.
The South African Convolvulaceae.
- A. Meeuse
- 4 December 1957
The first important contribution to the authors' knowledge of the South African Convolvulaceae was made by Thunberg who described or mentioned about 12 species, some of which were described or have since been recorded from the Union.
From ovule to ovary: A contribution to the phylogeny of the megasporangium
- A. Meeuse
- 1 September 1963
Die Herkunft der Blütenpflanzen von chlamydospermen- und bennettiteen-ähnlichen Vorfahren wird sehr wahrscheinlich da Übergänge zwischen den „nackten” Samenanlagen vomGnetum-Typ und sogenannten pseudomonomeren Griffeln von Angiospermen vorliegen.
