  • Narcissus Tazetta Drought Tolerant Bulbs for the Bay Area
    NARCISSUS TAZETTA DROUGHT TOLERANT BULBS FOR THE BAY AREA Joan Zwiep February 2016 NARCISSUS TAZETTA DROUGHT TOLERANT BULBS FOR THE BAY AREA Bulbs In botany, a geophyte or bulb, is a short stem with fleshy leaves or leaf ​ ​ ​ ​ ​ ​ bases that function as food storage organs during dormancy. The ​ ​ ​ ​ ​ underground storage organs of bulbs expend their food and water storage to produce the leaves and flowers. It is these underground food and water storage organs that allow these plants to resist drought. Bulbous plant species cycle through vegetative and reproductive growth stages; the bulb grows to flowering size during the vegetative stage and the plant flowers during the reproductive stage. During the wet season, bulbs replenish their resources from soil nutrients and photosynthesis. During the hot, dry season, bulbs go dormant storing their accumulated food supply while showing little to no sign of life above ground. In autumn or spring the plants sprout again to continue the cycle. It is these characteristics which make many bulbous plants suitable for our Mediterranean climate of mild, wet winters and then hot, dry summers. Narcissus For many, daffodils are the flower of spring, the harbinger of warmer weather and longer days. They belong to one of the few plant genera that gardeners in all regions of the United States can grow successfully. That’s not to say that all daffodils will grow in all regions; it’s just a matter of selecting the ones that will thrive in a particular climate zone. Narcissus is a genus of predominantly spring perennial plants in the ​ ​ ​ ​ ​ ​ Amaryllidaceae (amaryllis) family.

In order to reduce work, I am sowing fewer seeds and concentrating on selling excess stock which has been repotted in the current year. Some are therefore in quite small numbers. I hope that you find something of interest and order early to avoid any disappointments. Please note that my autumn seed list is included below. This means that seed is fresher and you can sow it earlier. Terms of Business: I can accept payment by either: • Cheque made out to "R Wallis" (n.b. Please do not fill in the amount but add the words “not to exceed £xx” ACROSS THE TOP); • PayPal, please include your email address with the order and wait for an invoice after I dispatch your order; • In cash (Sterling, Euro or US dollar are accepted, in this case I advise using registered mail).

  • Untangling Phylogenetic Patterns and Taxonomic Confusion in Tribe Caryophylleae (Caryophyllaceae) with Special Focus on Generic
    TAXON 67 (1) • February 2018: 83–112 Madhani & al. • Phylogeny and taxonomy of Caryophylleae (Caryophyllaceae) Untangling phylogenetic patterns and taxonomic confusion in tribe Caryophylleae (Caryophyllaceae) with special focus on generic boundaries Hossein Madhani,1 Richard Rabeler,2 Atefeh Pirani,3 Bengt Oxelman,4 Guenther Heubl5 & Shahin Zarre1 1 Department of Plant Science, Center of Excellence in Phylogeny of Living Organisms, School of Biology, College of Science, University of Tehran, P.O.

This challenge is most serious in tribe Caryophylleae since the supposed genera seem to be highly artificial, and the available morphological evidence cannot effectively be used for delimitation and exact determination of taxa. The main goal of the present study was to re-assess the monophyly of the genera currently recognized in this tribe using molecular phylogenetic data. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and the chloroplast gene rps16 for 135 and 94 accessions, respectively, representing all 16 genera currently recognized in the tribe Caryophylleae, with a rich sampling of Gypsophila as one of the most heterogeneous groups in the tribe.

  • Taxonomic, Pharmacognostic and Physicochemical Authentication of Colchicum Luteum Baker (Suranjantalkh) from Its Commercial Adulterant
    Pak. J. Bot., 48(5): 2039-2045, 2016. TAXONOMIC, PHARMACOGNOSTIC AND PHYSICOCHEMICAL AUTHENTICATION OF COLCHICUM LUTEUM BAKER (SURANJANTALKH) FROM ITS COMMERCIAL ADULTERANT SIDRA NISAR AHMED1, MUSHTAQ AHMAD1*, ZABTA KHAN SHINWARI2 AND SHELA SHINWARI1 1Department of Plant Sciences, Quaid-i-Azam University, Islamabad 45320, Pakistan 2Department of Biotechnology, Quaid-i-Azam University, Islamabad, Pakistan *Corresponding author’s e-mail: [email protected] Abstract The main objective of current study is to elucidate taxonomic, pharmacognostic and physicochemical behavior of Colchicum luteum (Suranjantalkh) for its proper identification and authentication from its cheap and tasteless adulterant. Colchicum luteum is one of the most rare and hence expensive medicinal plants. It is an active part of many unani formulations due to presence of an alkaloid colchicine which is claimed to be effective in arthritis, gout, rheumatism and internal injuries. In order to overcome demand of its corm, suppliers and herb sellers adultered bulbs of a monocotyledon plant Narcissus tazetta. This type of study reveals to be helpful in differentiating plants on basis of leaf epidermal anatomy, palynology, phamacognosy and physicochemical values. It is an important step in field of herbal medicine to provide pure and original medicinal plants to yield their maximum effectiveness.
