Foliose lichen growing from a tip of bark. Blue Mountains NP, Sydney. I realised late last week that I had forgotten to upload the last two micrographs! Dreadfully sorry; I was preparing my first 40-minute speech ever for the Australian Plants Society, who funded part of my Honours work on the genetic contamination of the Moreton Bay fig (Ficus macrophylla). I couldn’t be more pleased with how the talk went, and that speech also marks the beginning of my PhD. It was a good week! via ift.tt/1BJabwE
Snapped whilst out with the iPhone 4S scouting the location for potential SLR shots at a later date.

I am always trying to stretch (or in this case shrink) my photographic limits. If you look closely at your boxwood hedge you might find it blooming. I did and managed to photograph the flowers.
Day 12. One of the dropped flowers. There are two petals - one tall and rolled back in the manner of the bract, the other shorter and in front. The black-tipped parts are the stamens. The stigma is not visible in this view.

Caption: Fig. 5. Picea farjonii sp. nov., scanning electron micrographs of the transition between the leafy shoot and seed cone (PP55921). (A) Detail of distal part of the transition region between leafy shoot and cone showing a rudimentary bract (left arrow, see also (B)) and appressed peg-like leaf bases; note the scar left by abscised rudimentary bract (right arrow, also shown in C). (B) Detail of rudimentary bract in (A), arrow indicates the zone of abscission. (C) Detail of rhomboidal bract abscission scar in (A), note central vascular bundle (central arrow) and two lateral probable resin canals (lateral arrows). (D) Detail of the central vascular bundle from (C). (E) Detail of the proximal part of the transition region between leafy shoot and cone showing broken leaf base (upper arrow) and appressed peg-like leaf bases (lower arrow); note abscission zone (middle arrow). (F) Isolated leaf found attached to the shoot in (A) showing linear, flattened, form and smooth margin (squares indicate the areas shown in detail in (G) and (H)). (G) Detail of the leaf apex in (F) showing an acuminate tip and elongated epidermal cells. (H) Detail of the leaf base in (F) (partially bent) showing a more or less elliptical abscission scar and probable resin canal. (I) Isolated leaf found attached to the shoot in (A) showing two bands of stomata on the putative adaxial surface. (J) Detail of stomata (arrows) showing the stomatal aperture flanked by two sunken guard cells with two lateral and two polar subsidiary cells. Scale bars = 2.5 mm (A), 2 mm (F), 500 µm (B, C, E, and I), 100 µm (D, G, and H), 50 µm (J). www.nrcresearchpress.com/journal/cjb

I had never seen this tree before and I thought the bark was very intriguing. Beijing, China. June 4, 2015.

The IXUS 75 isn't bad for this purpose! There may be different species of Spirogyra here. The larger one has four spiral shaped strands of chloroplasts, whereas the small one in the background appears to have just one.

Mission
"To develop and maintain a diverse living collection of plants to support teaching and worldwide research in plant biology, further the conservation of plant diversity, and promote public understanding and appreciation of plants and the natural environment."
Who We Are
The UC Botanical Garden is a non-profit research garden and museum for the University of California at Berkeley, having a notably diverse plant collection including many rare and endangered plants. Established in 1890, the Garden, which is open to the public year round, has over 13,000 different kinds of plants from around the world, cultivated by region in naturalistic landscapes over its 34 acres.
History
A small garden of economic plants was established on the Berkeley campus on the site currently occupied by Moffit Library in the 1870’s by Dr. Eugene W. Hilgard (1833-1916), founding Dean of Agriculture . The University of California Botanical Garden was formally established in 1890 by E. L. Greene, the first chairman of the Department of Botany, to form a living collection of the native trees, shrubs, and herbaceous plants of the State of California, with the intent to gather in as rapidly as possible those of the neighboring states of the Pacific Coast. Within two years the collection numbered 600 species. In the following decade it grew to 1500, but then began to expand both its scope and collection to encompass plants from all continents and about 10,000 species.
The original official Garden was located near Haviland Hall on the north side of campus centered around a large glass conservatory modeled after the London Crystal Palace .
