Srgc Bulb Log Diary
SRGC ----- Bulb Log Diary ----- Pictures and text © Ian Young BULB LOG 18..................................4th May 2016 Yellow Erythronium grandiflorum and the pure white of Erythronium elegans, growing in the rock garden, are featured on this week’s cover picture. Despite all the extremes that our weather is delivering the flowering of the Erythroniums is at a peak just now. In one of the sand plunge beds a basket of Erythronium hendersonii opens its flowers responding to one of the sunny periods. View across the rock garden bed to one of the sand plunges. Erythronium revolutum hybrids These are two of the Erythronium revolutum hybrids that I lifted for assessment a few years ago. I grew them in pots for a year then transferred them into plunge baskets last summer to allow them more space to increase. They both have well-marked leaves and interesting markings in the flowers so the main thing I am trialling them for is to see how quickly they will increase. Erythronium ‘Joanna’ One of the plants that has suffered a bit in the bad weather is Erythronium ‘Joanna’. The flowers of this group, growing in a plunge basket, have become spotted with some withering at the tips while others planted out under the cover of Rhododendrons are fine. I also notice similar damage on flowers of Erythronium tuloumnense, one of the parents of E. ‘Joanna’. Erythronium ‘Craigton Cover Girl’ There is no doubt that the flowers of some species are more resistent to the cold wet conditions and that resilience is passed on to hybrids. Erythronium ‘Craigton Cover Girl’ has E. -

Jordan Toll Trail by William F
Jordan Toll Trail By William F. (Bill) Jordan In the year of 1860, there was a lot of verbal and political activity about the matter of building roads across the Sierra Mountains. In April, 1860, the Tulare County Supervisors appointed a committee to view a road and pack trail from Visalia to Mono. On January 30, 1860, the Visalia Delta announced that a company had been formed and application was made to the legislature to build a toll road from Visalia to Owens Lake. S. G. George, H. L. Mathews. S. Sweet, Henry Bostwick, John Jordan, and W. F. Jordan. About or before that time, the large Coso Silver and Gold Mines opened up. They were located southeast of Owens Lake up in the Coso Range of mountains, east of Owens Valley. The mines are what attracted all of this excitement. While all this talk and legislative action was going on, John Jordan and his son, William F. Jordan, were apparently going ahead with a toll trail project under the authority given by the Tulare County Board of Supervisors. The Jordan petition is on file at the Tulare County Courthouse and reads as follows: Saturday, March 30, 1861. whereas, the Board of Supervisors of Tulare County have this day passed a resolution instructing our Senator and Representative in the Legislature of the State of California, authorizing said County of Tulare to levy an additional road tax of 10 cents on each $100.00 worth of taxable property in said County. Now, therefore, if the Legislature shall pass the Act aforesaid, it is, by this Board ordered that all the taxes arising from the aforesaid special Act for one year, shall be applied to building and constructing a certain wagon road leading from San Luis Obispo County to Coso by the way of Visalia. -
Acmispon Helleri Notes
Sorrie, B.A. 2015. Notes on morphology of Acmispon helleri (Fabaceae). Phytoneuron 2015-44. 1–3. Published 15 July 2015. ISSN 2153 733X NOTES ON MORPHOLOGY OF ACMISPON HELLERI (FABACEAE) BRUCE A. SORRIE University of North Carolina Herbarium North Carolina Botanical Garden Chapel Hill, North Carolina 27599-3280 ABSTRACT Recent field observations of Acmispon helleri in North Carolina point out a number of discrepancies or omissions regarding published descriptions, including stem color and pubescence, leaflet morphology and vestiture, and corolla color. Degree of foliation strongly corresponds with phenology –– loss of leaves and leaflets over time appears to be common. Acmispon helleri (Britt.) A.A. Heller is the eastern segregate of the western and midwestern A. americanus (Nutt.) Rydb. and is restricted to scattered locations in the piedmont of south-central Virginia, North Carolina, South Carolina, and northeastern Georgia (Weakley 2015). It was formerly placed within Lotus, sometimes as a full species, sometimes as a variety (see Brouillet 2008 and Weakley 2015 for synonymy). Observations of living plants at sites in the lower piedmont of Union County, North Carolina, in 2010 suggest that several morphological characters are at variance with published descriptions. The most detailed description available is that of Wilbur (1963); also very helpful are the illustrations in Chafin (2007). Radford, Ahles, and Bell (1968) followed Wilbur in writing their description. 1. Stem color. Neither Wilbur nor Radford, Ahles, and Bell mention this. In the Union County plants, stems are wholly reddish brown. Branches are green, but often reddish brown basally. 2. Pubescence of stems and branches. Wilbur: stems and branches are "glabrate (especially below) to moderately spreading villous-pubescent." In the Union County plants, stems are sparsely to moderately villous throughout and branches moderately to densely villous. -
Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese -
A 1 Case-PR/ }*Rciofft.;Is Report
.A 1 case-PR/ }*rciofft.;is Report (a) This eruption site on Mauna Loa Volcano was the main source of the voluminous lavas that flowed two- thirds of the distance to the town of Hilo (20 km). In the interior of the lava fountains, the white-orange color indicates maximum temperatures of about 1120°C; deeper orange in both the fountains and flows reflects decreasing temperatures (<1100°C) at edges and the surface. (b) High winds swept the exposed ridges, and the filter cannister was changed in the shelter of a p^hoehoc (lava) ridge to protect the sample from gas contamination. (c) Because of the high temperatures and acid gases, special clothing and equipment was necessary to protect the eyes. nose, lungs, and skin. Safety features included military flight suits of nonflammable fabric, fuil-face respirators that are equipped with dual acidic gas filters (purple attachments), hard hats, heavy, thick-soled boots, and protective gloves. We used portable radios to keep in touch with the Hawaii Volcano Observatory, where the area's seismic activity was monitored continuously. (d) Spatter activity in the Pu'u O Vent during the January 1984 eruption of Kilauea Volcano. Magma visible in the circular conduit oscillated in a piston-like fashion; spatter was ejected to heights of 1 to 10 m. During this activity, we sampled gases continuously for 5 hours at the west edge. Cover photo: This aerial view of Kilauea Volcano was taken in April 1984 during overflights to collect gas samples from the plume. The bluish portion of the gas plume contained a far higher density of fine-grained scoria (ash). -
