IV. on the Proteaceć of Jussieu. by Mr. Robert Brown, Lib. LS
IV. On the Proteacea of Jussieu. By -Mr. Robert Brown, Lib. L.S. Read Jan. 17, 1809. THELinnean system of botany, though confessedly artificial, has not only contributed more than all others to facilitate tlie knowledge of species, but, by constantly directing the attention to those essential parts of the flower on which it is founded, has made us acquainted with more of their important modific-a t’ ions than we probably should have known, had it not been generally adopted, and has thus laid a more solid foundation for the esta- blishment of a natural arrangement, the superior importance of which no one has been inore fully impressed with than Linnzus hiinself. There are still, however, certain circumstances respccting the stamina and pistilla, which appear to iiie to havc been much less attended to than they deserve, both by Linneus and succeeding botanists. What I chiefly allude to is the state of these organs before the expansion of the flower. Tlie utility of ascertaining the internal condition of the ovarium before fecundation will liardly be called in question, now that the immortal worlis of Gxrtner and Jussieu hare demonstrated the necessity of minutely studying the fruits of plants in attempting to arrange tlicin ac- cording to tlic sum of their affinities, as in many cases the true nature of tlie ripc fruit, cspecially witli respect to the placenta- tion of the seeds, can oiily be detcrniined by this mc;~ns. Its importance is indeed expressly inculcated by many l~ot:inists, Tf’llO, 16 Mr. BROWN,on the Proteacee of Jussieu. -

Lizeth Swart Thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Agriculture at the University of Stellenbosch Supervisor: Prof. P. W. Crous Decem ber 1999 Stellenbosch University https://scholar.sun.ac.za DECLARATION 1, the undersigned, hereby declare that the work contained in this thesis is my own original work and has not previously in its entirety or in part been submitted at any university for a degree. SIGNATURE: DATE: Stellenbosch University https://scholar.sun.ac.za PATHOGENS ASSOCIATED WITH DISEASES OF PROTEA, LEUCOSPERMUM ANDLEUCADENDRONSPP. SUMMARY The manuscript consists of six chapters that represent research on different diseases and records of new diseases of the Proteaceae world-wide. The fungal descriptions presented in this thesis are not effectively published, and will thus be formally published elsewhere in scientific journals. Chapter one is a review that gives a detailed description of the major fungal pathogens of the genera Protea, Leucospermum and Leucadendron, as reported up to 1996. The pathogens are grouped according to the diseases they cause on roots, leaves, stems and flowers, as well as the canker causing fungi. In chapter two, several new fungi occurring on leaves of Pro tea, Leucospermum, Telopea and Brabejum collected from South Africa, Australia or New Zealand are described. The following fungi are described: Cladophialophora proteae, Coniolhyrium nitidae, Coniothyrium proteae, Coniolhyrium leucospermi,Harknessia leucospermi, Septoria prolearum and Mycosphaerella telopeae spp. nov. Furthermore, two Phylloslicla spp., telopeae and owaniana are also redecribed. The taxonomy of the Eisinoe spp. -
Blushing Bride FAMILY NAME: Proteaceae Species and Cultivars Of
Plant Profile Botanical Name: Serruria florida Common Name: Blushing Bride FAMILY NAME: Proteaceae Species and cultivars of special interest: Serruria florida hybrids and cvv. such as ‘Sugar ’n’ Spice’, ‘Pretty in Pink’, ‘Super Blush’, ‘Carmen’ Origin: South Africa Availability: May to October Foliage Characteristics: Stem length is 30- 60 cm. They have papery white bracts or floral leaves surrounding the flower. The sugar and spice variety has pink on the white bracts too. 5- 10 stems per bunch. Floral Characteristics: Blushing bride have feathery tufts of white to pinkish flowers. Sugar and spice variety has pink flowers. Special features and characteristics of special interest: It is thought that blushing bride got its name because of its traditional use in Africa as bridal bouquets. The species was near extinction due to being over exploited until conservation measures in the 1960s and 70s kicked in. Botanical name given in honour of James Serrurier, an 18th century professor of Botany at the Unisversity of Utrecht. Maintenance, Cultural requirements and Post Harvest Treatments: Blushing Bride is grown on large bushes in plantations across Australia. They are also grown in South Africa, Israel and the US. Handle blushing brides gently as flowers dry out quickly. They can have floral preservative. It is unknown whether it is Ethylene sensitive. When stored in cool storage keep at at 2- 4 degrees. Strip leaves from water level down. Pest and Diseases: The pedicels are vulnerable to Botrytis infection, which causes them to collapse. They do not suffer from leaf blackening like protea species do but the leaves may turn black if submerged in buckets of solution or if held for too long. -

Anatomical Adaptations in the Leaves of Selected Fynbos Species
S.Afr.J.Bot., 1994, 60(2): 99 - 107 99 Anatomical adaptations in the leaves of selected fynbos species Al ison M. van der Merwe (nee Summerfield),· J.J.A. van der Walt and Elizabeth M. Marais Department of Botany, University of Stellenbosch, Stellenbosch, 7600 Republic of South Africa Received 23 August 1993; revised 6 December 1993 Fynbos plants experience very harsh conditions during the hot and dry summer months and their leaves are adapt ed to reduce the loss of water due to transpiration. The leaves of 46 selected fynbos species of 24 families were examined to determine which anatomical adaptations contribute to the reduced rate of transpiration and subse quent reduced water loss. Without exception, all species examined show leaf adaptations typical of xerophytic species. Four typical leaf types are recognized and proposed as models of leaf adaptation: 1. Myrsine type - dorsi ventral or isobilateral leaves; more palisade parenchyma present than spongy parenchyma; tissues contain large amounts of phenolic substances. 2. Meta/asia type - small dorsiventral leaves with involute margins and a single groove in the adaxial surface; mesophyll is usually inverted. 3. Retzia type - dorsi ventral or isobilateral leaves with revolute margins and one or two grooves in the abaxial surface; spongy parenchyma is the main component of the mesophyll. 4. Spatalla type - small centric or near-centric leaves; little or no spongy parenchy ma tissue. Fynbos plante ondervind uiterste toestande tydens die warm, droa somermaande, en hulle blare is aangepas om waterverlies tydens transpirasie te beperk. Blare van geselekteerde fynbos-spesies uit 24 families is ondersoek am die bydrae van die verskillende anatomiese aanpassings tot verminderde transpirasietempo en gevolglike water verlies, vas te stel. -
