Davidia Involucrata Handkerchief Tree
Davidia involucrata Handkerchief Tree Davidia involucrata is the only member of its genus but there are two varieties separated by their leaves, var. involucrata which whose leaves are short haired on the underside and var. vilmoriniana which have hairless leaves. A small/medium sized tree it is most well known for its astonishing white, large bracts that hang like pinched handkerchiefs from its branches in May. The foliage is midsized and heart shaped, of a attractive green colour in summer turning shades of orange and yellow in winter with young foliage in spring having a red/purple colour and a spicy, incense fragrance. Small inedible pear shaped fruits are produced in the spring.

This is an open-access article distributed under the terms of the Creative Commons Attribution ShareAlike (CC BY-SA) 4.0 License. ABSTRACT. Davidia involucrata, reputed to be a “living fossil” in the plant kingdom, is a relict tree endemic to China. Extant natural populations are diminishing due to anthropogenic disturbance. In order to understand its ability to survive in a range of climatic conditions and to design conservation strategies for this endangered species, we developed genic simple sequence repeats (SSRs) from mRNA transcripts. In total, 142,950 contigs were assembled. Of these, 30,411 genic SSR loci were discovered and 12,208 primer pairs were designed. Dinucleotides were the most common (77.31%) followed by trinucleotides (16.44%). Thirteen randomly selected primers were synthesized and validated using 24 individuals of D. involucrata. The markers displayed high polymorphism with the number of alleles per locus ranging from 3 to Genetics and Molecular Research 15 (4): gmr15048539 Z.C. Long et al. -

Many of these landscapes cannot be isolated from the énclave as they are integral to and part of its cultural mosaic and character. Perhaps the most important are the Penang Hill hill-station landscape and the ‗Waterfall‘ Botanic Gardens. The latter is an under-valued ‗garden of the empire‘—a garden that significantly underpinned the development and historical and botanical stature of the Singapore Botanic Gardens. This paper reviews the cultural significance of colonial botanic gardens as they were established around the world during the scientific explosion of the late 1800s. -

246 Combined Proceedings International Plant Propagators’ Society, Volume 52, 2002 The Role of the Veitch Nursery of Exeter in 19th Century Plant Introductions 247 Among interesting perennials are the luxuriant Myosotidium hortensia, the Chatham Island forget-me-not; blue poppies such as Meconopsis betonicifolia, M. grandis and the hybrid ‘Lingholm’; and many members of the Iridaceae such as Dietes, Diplarrhena, Libertia, Orthrosanthus, and Watsonia. The very distinctive Arisaema do well here, as do an increasing number of plants in the Convallaria- ceae, including Disporum, Polygonatum, Smilacina, Tricyrtis, and Uvularia. PLANTING CONDITIONS The windy conditions discourage the planting of large specimens, though the shallow soil in some places makes this physically impossible, while the severe infes- tation of honey fungus, Armillaria sp., precludes the direct transplanting of woody plants, which eventually fall victim to the fungus. Lifted rhododendrons are potted into very wide, shallow containers for a year or two before being surface planted, a method which has become the rule without cultivated beds, by simply placing the rootball on the soil and mounding up with the chosen medium. This seems to encourage establishment and may slow the invading Armillaria. Where rhododen- drons are planted on mossy rocks or stumps, particular care has to be taken during dry periods as the lack of mains water or any distribution system makes watering practically impossible and establishment unlikely.
