Originally occurs on wooded mountain slopes in Japan and China. The grey-brown aromatic bark carries a light network of grooves and flakes off in platelets. The twigs start out hairy but are later bare. The large, ovoid to oval leaves are tapered. The upper side is fresh green, the underside grey-green. Bell- shaped white flowers with a diameter of approx. 1 cm appear in June/July. They have a strong and pleasant smell and are grouped in plumes measuring up to 20 cm. After flowering, large green drupes appear, approx. 1 cm in size. They bear rough hairs and have 5 ribs. Pterostyrax prefers neutral to slightly acid, well drained soil. It can also take calcareous soils. It is a particularly remarkable sight when in full bloom. Pterostyrax hispida is sometimes called the 'epaulette tree' because the flowers resemble the decoration on the shoulders of uniform jackets. The tree only produces abundant flowers after the passage of a few years. © Copyright Boomkwekerij Gebr. Van den Berk B.V. 2021.

I was invited to intern with Grounds to create this biography through the mentorship of Janice Murphy and Shannon Britton; it was gratifying and exciting to be able to use the knowledge I’ve gained in my time here to help add to the depth of the beautiful garden that is the Seattle University campus. I hope that this biography serves as a resource for anyone looking to become more acquainted with the flora on campus, and that my photography portrays the trees in a way that does them justice. The Trees of Seattle University campus map was designed and illustrated by A lyssa Lau, a Seattle University graduate in the class of 2018. Alyssa created the map to use her graphic design skills to promote education about the biodiversity on campus. Alyssa also created all of the tree drawings on the map, she did them by hand with colored pencil to capture the organic nature of the trees. Fujitaro Kubota was a legendary Japanese landscaper who emigrated to the United States in 1907 and worked on the Seattle U campus in the late 1950s and ‘60s. His family business, the Kubota Gardening Company, is still operating today and the garden headquarters can be visited in Renton, WA.

Read Full License Page 1/25 Abstract Background: The Styracaceae are a woody, dicotyledonous family containing 12 genera and an estimated 160 species. Recent studies have shown that Styrax and Sinojackia are monophyletic, Alniphyllum and Bruinsmia cluster into a clade with an approximately 20-kb inversion in the Large Single-Copy (LSC) region. Halesia and Pterostyrax are not supported as monophyletic, while Melliodendron and Changiostyrax always form sister clades . Perkinsiodendron and Changiostyrax were newly established genera of Styracaceae. However, the phylogenetic relationship of Styracaceae at the genera level needs further research. Results: We collected 28 complete plastomes of Styracaceae, including 12 sequences newly reported here and 16 publicly available complete plastome sequences, comprising 11 of the 12 genera of Styracaceae. All species possessed the typical quadripartite structure of angiosperm plastomes, and the sequence difference is small, except for the large 20-kb (14 genes) inversion region found in Alniphyllum and Bruinsmia. Seven coding sequences (rps4, rpl23, accD, rpoC1, psaA, rpoA and ndhH) were identied to possess positively selected sites. Phylogenetic reconstructions based on seven data sets (i.e., LSC, SSC, IR, Coding, Non-coding, combination of LSC+SSC and concatenation of LSC+SSC+one IR) produced similar topologies.

The length of the Symplocos chloroplast genome ranged from 156,961 to 157,365 bp. Overall, 132 genes including 87 functional genes, 37 tRNA genes, and eight rRNA genes were identified in all Symplocos chloroplast genomes. The gene order and contents were highly similar across the seven species. The coding regions were more conserved than the non- coding regions, and the large single-copy and small single-copy regions were less conserved than the inverted repeat regions. We identified five new hotspot regions (rbcL, ycf4, psaJ, rpl22, and ycf1) that can be used as barcodes or species-specific Symplocos molecular markers. These four novel chloroplast genomes provide basic information on the plastid genome of Symplocos and enable better taxonomic characterization of this genus.

– Sortimentsoverzicht Ir
Pterostyrax – Sortimentsoverzicht Ir. J.J.C. Janssen Pterostyrax wordt Epaulettenboom of Vleugelstorax genoemd. De bloeiwijze van Pterostyrax doet enigszins denken aan een epaulet, de schouderversiering van een uniform. Vleugelstorax is niets anders dan een vertaling van de wetenschappelijke naam. Het is na Styrax en Halesia de bekendste vertegenwoordiger van de familie Styracaceae. De rijke bloei met witte geurende bloemen in lange hangende pluimen is erg opvallend. Het is de belangrijkste reden voor aanplant van deze attractieve, soms meerstammige bomen. Dit artikel probeert een bijdrage te leveren aan een grotere bekendheid en een beter gebruik van het kleine interessante geslacht Pterostyrax . Morfologie De vrucht bevat 1 of 2 vlezige zaden.

Wilson's Controversial Magnolia and the Mysterious Wa Shan
photograph © President and Fellows of Harvard College. Arnold Arboretum Archives. Wilson’s photo of Wa Shan. “The fog prevented my view of the wild and savage scenery for which this stretch is famed. I was very disappointed as I was keen on getting some photos” (Wilson’s diary 18 September, 1908); “the Mt. covered in dense cloud all day” (19 September); “Mt. Wa was clear, 52 and I took 3 photos from different positions” (20 September). Wilson’s controversial magnolia and the mysterious Wa Shan As is so often the case, what was expected to be a leisurely pursuit of magnolia study in the tranquil atmosphere of the Australian Bicentennial Arboretum, turned out to be an exciting adventure into the wilderness of China’s remote and elusive Wa Shan, a mountain shrouded in mist and mystery. This is such a tale when CHRIS CALLAGHAN and SK PNG went searching for Wilson’s controversial Magnolia sargentiana var. robusta in a quest to shed further light on its botanical status and ended up rediscovering a mountain potentially richer in flora than Emei Shan! While researching the identity of what was found to be probably the first recorded hybrid of Magnolia sargentiana var. sargentiana (see ‘Bicentennial’ – a new hybrid magnolia cultivar, in the 2008 IDS Yearbook, pp. 53 - 61), I became aware of a controversy surrounding the botanical status of Magnolia sargentiana var. robusta, the few plants of which were discovered by Ernest Wilson in woodlands and open country on Wa Shan in Sichuan province, INTERNATIONAL DENDROLOGY SOCIETY TREES photograph © Australian Bicentennial Arboretum Da-tien Chi at base of Wa Shan in October 2009.

Druid Hills- Recommended Plant Materials List
9.0 Cultural Landscapes Guidelines - Maintainin Recommendation - The following plant list is intended to assist in the selection of appropriate plant materials. The list has been organized into large trees, small trees, shrubs, annuals/perennials, and vines/ground covers. The list has been developed using the following sources: (1) Olmsted’s Planting List from several plans for Druid Hills; (2) Historic Plants compiled as part of the Georgia Landscapes Project by the Historic Preservation Division of the Georgia Department of Natural Resources; and (3) Native Species. Aggressive exotics have also been noted, so that their use can be limited to controlled situations. (Refer to Section 8.1 Open Space and Parkland Preservation and Conservation: Eradication of Exotic Example of Species.) planting of Bradford Pears Olmsted’s list and the list from the Georgia Landscapes Project provide guidance in selecting materials within intrusion appropriate for historic landscape projects. The Olmsted list has been updated with current plant names. areas within the district. There are other sources that can be consulted to identify additional plants used by Olmsted in Druid Bradford Pear is Hills, such as historic planting plans and, particularly the archival record at the Olmsted National His- nonhistoric tree toric Site in Brookline, Massachusetts. The Olmsted list presented in this document should be considered that would not be a beginning.

Here, we use a modelling approach to evaluate the phylogenetic conservatism; hypothesis that nectar sucrose proportion (NSP) is an adaptation to pollina- phylogenetic constraint; tors. We analyse ~ 2100 species of asterids, spanning several plant families pollination syndrome; and pollinator groups (PGs), and show that the hypothesis of adaptation sucrose. cannot be rejected: NSP evolves towards two optimal values, high NSP for specialist-pollinated and low NSP for generalist-pollinated plants. However, the inferred adaptive process is weak, suggesting that adaptation to PG only provides a partial explanation for how nectar evolves. Additional factors are therefore needed to fully explain nectar evolution, and we suggest that future studies might incorporate ﬂoral shape and size and the abiotic envi- ronment into the analytical framework.

I’d like to first thank my committee members, Dr. John Frett, Dr. Tom Pizzolato, and Dr. Tomasz Aniśko for their guidance throughout all phases and aspects of the project. I’d also like to thank the late Dr. J.C. Raulston for his interest in the group, who was arguably the most important player in terms of raising awareness of Styrax from merely an odd, predominantly Asian relative of the Halesia, to a far more diverse group, now gaining recognition in both gardens and the nursery trade. Next, I’d like to thank Dr. Peter Fritsch of the California Academy of Sciences both for providing me with several references to aid in my understanding of the genus, many from his recent work with the systematics of Styrax, making the cultivated component of the group much easier to understand.
