    Appendix Color Plates of Solanales Species The first half of the color plates (Plates 1–8) shows a selection of phytochemically prominent solanaceous species, the second half (Plates 9–16) a selection of convol- vulaceous counterparts. The scientific name of the species in bold (for authorities see text and tables) may be followed (in brackets) by a frequently used though invalid synonym and/or a common name if existent. The next information refers to the habitus, origin/natural distribution, and – if applicable – cultivation. If more than one photograph is shown for a certain species there will be explanations for each of them. Finally, section numbers of the phytochemical Chapters 3–8 are given, where the respective species are discussed. The individually combined occurrence of sec- ondary metabolites from different structural classes characterizes every species. However, it has to be remembered that a small number of citations does not neces- sarily indicate a poorer secondary metabolism in a respective species compared with others; this may just be due to less studies being carried out.

  • Checklist of the Vascular Alien Flora of Catalonia (Northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3
    BOTANICAL CHECKLISTS Mediterranean Botany ISSNe 2603-9109 https://dx.doi.org/10.5209/mbot.63608 Checklist of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3 Received: 7 March 2019 / Accepted: 28 June 2019 / Published online: 7 November 2019 Abstract. This is an inventory of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) updated to 2018, representing 1068 alien taxa in total. 554 (52.0%) out of them are casual and 514 (48.0%) are established. 87 taxa (8.1% of the total number and 16.8 % of those established) show an invasive behaviour. The geographic zone with more alien plants is the most anthropogenic maritime area. However, the differences among regions decrease when the degree of naturalization of taxa increases and the number of invaders is very similar in all sectors. Only 26.2% of the taxa are more or less abundant, while the rest are rare or they have vanished. The alien flora is represented by 115 families, 87 out of them include naturalised species. The most diverse genera are Opuntia (20 taxa), Amaranthus (18 taxa) and Solanum (15 taxa). Most of the alien plants have been introduced since the beginning of the twentieth century (70.7%), with a strong increase since 1970 (50.3% of the total number). Almost two thirds of alien taxa have their origin in Euro-Mediterranean area and America, while 24.6% come from other geographical areas. The taxa originated in cultivation represent 9.5%, whereas spontaneous hybrids only 1.2%. From the temporal point of view, the rate of Euro-Mediterranean taxa shows a progressive reduction parallel to an increase of those of other origins, which have reached 73.2% of introductions during the last 50 years.

Pollen tube growth rates (PTGRs) of angiosperms are exceptionally rapid, a pattern 25 attributed to more effective haploid selection under stronger pollen competition. Paradoxically, 26 whole genome duplication (WGD) has been common in angiosperms but rare in gymnosperms.

Here we provide keys to all 135 species of Solanum native and naturalised in Africa (as defined by World Geographical Scheme for Recording Plant Distributions): continental Africa, Madagascar (incl. the Indian Ocean islands of Mauritius, La Réunion, the Comoros and the Seychelles), Macaronesia and the Cape Verde Islands. Some of these have previously been pub- lished in the context of monographic works, but here we include all taxa.

  • Flowering Vines for Florida1 Sydney Park Brown and Gary W
    CIRCULAR 860 Flowering Vines for Florida1 Sydney Park Brown and Gary W. Knox2 Many flowering vines thrive in Florida’s mild climate. By carefully choosing among this diverse and wonderful group of plants, you can have a vine blooming in your landscape almost every month of the year. Vines can function in the landscape in many ways. When grown on arbors, they provide lovely “doorways” to our homes or provide transition points from one area of the landscape to another (Figure 1). Unattractive trees, posts, and poles can be transformed using vines to alter their form, texture, and color (Figure 2).Vines can be used to soften and add interest to fences, walls, and other hard spaces (Figures 3 and 4). Figure 2. Trumpet honeysuckle (Lonicera sempervirens). Credits: Gary Knox, UF/IFAS A deciduous vine grown over a patio provides a cool retreat in summer and a sunny outdoor living area in winter (Figure 5). Muscadine and bunch grapes are deciduous vines that fulfill that role and produce abundant fruit. For more information on selecting and growing grapes in Florida, go to http://edis.ifas.ufl.edu/ag208 or contact your local UF/IFAS Extension office for a copy. Figure 1.

The compound, named luciamin, was characterised by NMR spectroscopy, mass spectrometry and chemical methods, as (22R,25S)-spirost-5-en-3 b,15a- diol 3-O-{b-d-glucopyranosyl (1!2)-b-d-glucopyranosyl-(1!4)-[a-l-rhamnopyranosyl-(1!2)]-b-d-galactopyranoside}. The com- pound was tested against the aphid Schizaphis graminum by incorporation in arti®cial diets. It showed a deterrent (toxic) activity against the insect and is the ®rst spirostane glycoside reported to have this activity. # 2000 Elsevier Science Ltd. All rights reserved.

Several classes of compounds, including alkaloids (ZuÂnÄ iga et al., 1985), ¯avonoids and related compounds (Dreyer and Jones, 1981), and diterpenes (Rose et al., 2. Results and discussion 1981), are toxic for and/or deter feeding of herbivores and insects. The Solanaceae family is a rich source of The material obtained after ethanolic extraction of active secondary metabolites.
