  • Heptacodium Miconioides
    photograph © Peter Del Tredici, Arnold Arboretum of Harvard University An old multi-stemmed specimen of Heptacodium miconioides growing in woodland on Tian Tai Shan, Zhejiang, September 2004, probably the first wild plant ofHeptacodium to be seen by a Western botanist since its discovery by Ernest Wilson in 1907. Heptacodium miconioides Rehder In his last ‘Tree of the Year’, JOHN GRIMSHAW discusses what distinguishes a shrub from a tree and writes about a large shrub introduced to cultivation first in the early twentieth century and again in the late twentieth century, that is rare in the wild. Introduction When the terms of reference for New Trees were drawn up (see pp. 1-2), having agreed that the book would contain only trees, we had to address the deceptive question ‘what is a tree?’ Most of us ‘can recognise a tree when we see one’ and in many ways this is as good an answer as one needs, but when is a woody plant not a tree? When it’s a shrub, of course – but what is a shrub? In the end we adopted the simple definitions that a tree ‘normally [has] a single stem reaching or exceeding 5 m in height, at least in its native habitat. A shrub would normally have multiple woody stems emerging from the base or close to the ground, and would seldom exceed 5 m in height’ (Grimshaw & Bayton 2009). In most cases this served to make a clear distinction, but one of the casualties that fell between the two stools was the Chinese plant Heptacodium miconioides, a significant recent introduction described by theFlora of China (Yang et al.

    J. AMER. Soc. HORT. SCI. 116(4):646-650. 1991. Growth Responses of Heptacodium miconioides to Various Photoperiods and Day/Night Temperatures Chin Chin Leel, Ted E. Bilderback2, and Judith F. Thomas3 North Carolina State University, Raleigh, NC 27695-7609 Additional index words. long-day plant, Heptacodium jasminoides Abstract. Photoperiod treatments of 10, 12, 14, and 16 hours and a field control were used to determine the photope- riodic response of Heptacodium miconioides Rehd. The F values for vegetative growth responses under various pho- toperiods exhibited a highly significant linear effect. Leaf count, area, and weight, shoot length, and stem weight were lower for plants exposed to the 10- or 12-hour photoperiod than those of plants grown under the 14- or 16-hour photoperiod or in the field. Plants under the 10- or 12-hour photoperiod became dormant after 5 weeks of treatment. The growth responses for the 10- and 12-hour photoperiods were similar. There also were no differences in growth responses of plants from the 14- and 16-hour photoperiods or from the field. A favorable photoperiod for growth of Heptacodium must exceed 12 hours; thus, it can be classified as a long-day plant in reference to vegetative growth. Leaf tissues under the 10- and 12-hour photoperiods were significantly thicker than those under the 14- and 16-hour periods or under field conditions due to longer cells of the palisade mesophyll layer. Plants grown in the field and under the 14- or 16-hour photoperiods were the only ones that initiated inflorescences. With days at 30C, leaf and stem dimensions were larger than those at 22C.

Relationships within Caprifolieae, however, remain quite uncertain, and the monophyly of Lonicera, the most species-rich of the traditional genera, and its subdivisions, need to be evaluated. In this study we used sequences of the ITS region of nuclear ribosomal DNA and five chloroplast non-coding regions (rpoB–trnC spacer, atpB–rbcL spacer, trnS–trnG spacer, petN–psbM spacer, and psbM–trnD spacer) to address these problems. Our results indicate that Heptacodium is sister to Caprifolieae, Triosteum is sister to the remaining genera within the tribe, and Leycesteria and Symphoricarpos form a clade that is sister to a monophyletic Lonicera. Within Lonicera, the major split is between subgenus Caprifolium and subgenus Lonicera. Within subgenus Lonicera, sections Coeloxylosteum, Isoxylosteum, and Nintooa are nested within the paraphyletic section Isika. Section Nintooa may also be non-monophyletic.

  • Dipsacales Phylogeny Based on Chloroplast Dna Sequences
    DIPSACALES PHYLOGENY BASED ON CHLOROPLAST DNA SEQUENCES CHARLES D. BELL,1, 2 ERIKA J. EDWARDS,1 SANG-TAE KIM,1 AND MICHAEL J. DONOGHUE 1 Abstract. Eight new rbcL DNA sequences and 15 new sequences from the 5' end of the chloroplast ndhF gene were obtained from representative Dipsacales and outgroup taxa. These were analyzed in combination with pre- viously published sequences for both regions. In addition, sequence data from the entire ndhF gene, the trnL-F intergenic spacer region,the trnL intron,the matK region, and the rbcL-atpB intergenic spacer region were col- lected for 30 taxa within Dipsacales. Phylogenetic relationships were inferred using maximum parsimony and maximum likelihood methods. Inferred tree topologies are in strong agreement with previous results from sep- arate and combined analyses of rbcL and morpholo gy, and confidence in most major clades is now very high. Concerning controversial issues, we conclude that Dipsacales in the traditional sense is a monophyletic group and that Triplostegia is more closely related to Dipsacaceae than it is to Valerianaceae. Heptacodium is only weakly supported as the sister group of the Caprifolieae (within which relationships remain largely unresolved), and the exact position of Diervilleae is uncertain. Within Morinaceae, Acanthocalyx is the sister group of Morina plus Cryptothladia. Dipsacales now provides excellent opportunities for comparative studies, but it will be important to check the congruence of chloroplast results with those based on data from other genomes.

  • Population Genetic Structure and Evolutionary History Of
    Population genetic structure and evolutionary history of Psammochloa villosa (Trin.) Bor (Poaceae) revealed by AFLP marker Xu Su1 and Ting Lv2 1Qinghai Normal University 2Affiliation not available February 18, 2021 Abstract We sought to generate a preliminary demographic framework for Psammochloa villosa to support of future studies of this ecologically important desert grass species, its conservation, and sustainable utilization. Psammochloa villosa occurs in the Inner Mongolian Plateau where it is frequently the dominant species and is involved in sand stabilization and wind breaking. Here, we characterized the genetic diversity and structure of 210 individuals from 43 natural populations of P. villosa using amplified fragment length polymorphism (AFLP) markers. We obtained 1728 well-defined amplified bands from eight pairs of primers, of which 1654 bands (95.72%) were polymorphic.All these values indicate that there is abundant genetic diversity, but limited gene flow in P. villosa. However, an analysis of molecular variance (AMOVA) showed that genetic variation mainly exists within 43 populations of the species (64.16%), and we found that the most genetically similar populations were often not geographically adjacent. Thus, this suggests that the mechanisms of gene flow are surprisingly complex in the species and may occur over long distances. In addition, we predicted the distribution dynamics of P. villosa based on the spatial distribution modeling and found that its range has contracted continuously since the last inter-glacial period. We speculate that dry, cold climates have been critical in determining the geographic distribution of P. villosa during the Quaternary period. Our study provides new insights into the population genetics and evolutionary history of P.

  • Heptacodium Miconioidesmiconioides Seven-Sonseven-Son Flower,Flower, Autumnautumn Lilaclilac
    HeptacodiumHeptacodium miconioidesmiconioides Seven-sonSeven-son flower,flower, AutumnAutumn lilaclilac Heptacodium miconioides(Seven-son flower, Autumn lilac) was discovered by English plant collector and botanist Ernest Wilson in the Chinese province Hubei in July 1907, and then described by the German botanist Alfred Rehder. The tree wasn’t distributed until 1980, by seeds from the botanical garden in Hangzhou, China. The seven-son flower is rarely found in nature, and occurs in small populations in the Chinese provinces Anhui and Zhejiang. What is remarkable about this tree is that it grows to be larger in cultivation than in nature. The species grows to a maximum of 8 metres tall, and 6 metres wide. It forms an irregular, round to vase-shaped crown. The cream-white bark of the Heptacodium miconioides that peels off in long sheets is lovely to see year-round, but is particularly striking in winter. The tree has a tropical look to it with three parallel, reddish veins on dark green, smooth-edged and undulating leaves. The foliage sometimes turns a purply green in autumn. Despite Alfred Rehder calling the species Heptacodium (Hepta meaning ‘seven’ in Greek), each panicle has six flowers. The buds already appear in June, after which the fragrant flowers appear in late August, and stay on the tree until early October. With its late, rich blossoms, the species is not only beautiful for people to see; it is also very valuable to bees. After blooming, the tree bears striking, red-violet fruit that stays on the tree for a long time. Heptacodium miconioides is often used as a multi-stem tree in gardens and park-like settings, where the tree adds great decorative value all year long.

Box 2437, BE-3001 Leuven, Belgium and 2Nationaal Herbarium Nederland, Leiden University Branch, P.O. Box 9514, NL-2300 RA Leiden, The Netherlands Received: 2 September 2008 Returned for revision: 9 January 2009 Accepted: 24 April 2009 Published electronically: 5 June 2009 † Background and Aims The Diervilla and Lonicera clades are members of the family Caprifoliaceae (Dipsacales sensu Donoghue et al., 2001, Harvard Papers in Botany 6: 459–479). So far, the intergeneric relationships of the Lonicera clade and the systematic position of Heptacodium remain equivocal. By studying fruit and seed mor- phology and anatomy, an attempt is made to clarify these issues. In addition, this study deals with the evolution of fruit and seed characters of the Diervilla and Lonicera clades with reference to allied taxa. † Methods Light and scanning electron microscopy were used for the morphological and anatomical investi- gations. Phylogenetic analyses were carried out by applying the parsimony and Bayesian inference optimality criteria. Character evolution was studied by means of parsimony optimization and stochastic character mapping. † Key Results Diervilla and Weigela (Diervilla clade) are characterized by several unique traits in Dipsacales, including capsules with numerous seeds, seed coats without sclerified outer tangential exotestal cell walls, and dehiscent fruits. Seeds with completely sclerified exotestal cells and fleshy fruits characterize the Lonicera clade.
