On the thorns of a dilemma

The question is – are they long? or long enough? or longer than the other ones? And are the leaves first? or the blossom? Lucy Corrander at Loose and Leafy explains how it’s not always easy to tell the haw- from the black- when it comes to thorns.

Rainbow eucalyptus at the Huntingdon Botanical Gardens

treeaware - rainbow eucalyptus

Gillian Ware shares a photo gallery of rainbow eucalyptus (Eucalyptus deglupta) at her Tree A. Ware blog.

Apart from being a magic tree, it has two magic common names: Rainbow Eucalyptus and Painted Bark Eucalyptus, both descriptive of its multicoloured bark. Like other Eucalyptus’ it sheds its bark— but in this case the lower layer is a vivid green. As different layers mature, they change colour— to orange, purples and blues, dark maroon being the final colour— resulting in fantastic paint brushstroke-like streaks.

Myrrh: the many uses of a hostile tree

Hadzabe near Lake Eyasi use Commiphora to light firesAt Safari Ecology blog, Colin has followed up a fascinating post on why so many trees and shrubs in the African savanna are so thorny with one on a particularly useful thorny tree, myrrh (Commiphora). A bunch of recent studies have borne out the anti-viral and anti-bacterial properties of its sap, which has been used to treat infections at least since the ancient Sumerians. Myrrh trees also make good habitat, their berries are an important food source for a number of species, and — well, just read Colin’s post.

A worship-worthy tree

Madrone by Jill WussowField biologist and photographer Jill Wussow shares some lovely photos of Texas madrones at her somewhat alarmingly titled blog Count Your Chicken! We’re Taking Over! “If you haven’t seen the glory of these bad boys,” she says, “I suggest you book it over to Texas or New Mexico when you get the chance and worship them just a little bit.”

Bay laurel

From The Medieval Garden Enclosed, the blog of the Cloisters Museum and Garden in New York, a wonderful portrait of a storied tree:

The ancient Greek story of the transformation of a river nymph into a laurel tree was immortalized in the Roman poet Ovid’s Metamorphoses (Book 1, 452–53), a work that enjoyed great popularity in the Middle Ages. The story of Apollo’s pursuit of the unwilling Daphne has captivated poets as well as artists over many centuries, inspiring such famous interpretations as Antonio Pollaiuolo’s painting in the National Gallery and Gian Lorenzo Bernini’s sculpture in the Villa Borghese.

How old are baobabs, and why don’t we see any small ones?

Only a baobab can make a giraffe look puny.

Baobabs are one of the most impressive trees in the East African savanna landscape, and ecologist Colin Beale at Safari Ecology blog says he’s often asked two questions about them: how old are they? And why don’t we see baby baobabs? This blog post explores some recent answers to those questions.

(I’m grateful to Colin for the submission, not only because he’s summarizing a research paper not available on the open web, but also because seeing baobabs is one of my life goals. As a matter of fact, I just mentioned my baobab-longing yesterday — if y’all will indulge me a link to my own blog — in a post called “Strange trees.”)

Coconut palm: “the most useful tree on earth”

coconut sproutFrom Lower Dover Field Journal, a comprehensive portrait of the coconut palm. I wasn’t aware of all the health benefits:

Recent western medicinal research concluded that coconuts’ form of saturated fat actually helps to prevent heart disease, stroke and the hardening of arteries. Unlike other oils and fats, coconut oil contains a large amount of the fatty acid known as lauric acid, which is the predominant fatty acid found in mother’s milk. Studies have shown the coconut oil’s effectiveness against HIV, SARS, Crohn’s disease, as well as other chronic illnesses. It detoxifies the liver, helps to build lipoproteins, fats, hormones, and bile. Coconut’s amazing healing properties are also attributed to reducing the risk of other degenerative conditions such as cancer, osteoporosis, and diabetes. The fatty acids help to create a healthy digestive tract, which in turn allows for better digestion and absorption of the nutrients in our foods. They also speed up metabolism, providing fewer calories than other fats but are still a viable effective source of energy.

If you could follow one tree for a year, what would it be?

British blogger Lucy Corrander at Loose and Leafy followed a sycamore tree last year, but says its size was a disadvantage — “all the ‘action’ happens high up. At ground level, shade and location mean it’s not a good place for other plants to grow… what little there is that struggles into life between its toes tends to get nibbled as soon as it shows its head above ground.” She doesn’t want to blog about trees in isolation, but as members of an ecological community.

So this year’s tree, by contrast, is part of a small but dense clump of vegetation, and is so small and “scraggy,” it’s “hardly a tree at all.” But a tree it is, and one of some significant folkloric and even exotic appeal to this North American reader (though we do have a closely related member of the same genus). What’s the species? Read the post to find out.

Rubber trees and the Mayan ball game

Lower Dover Rubber TreeThe rubber tree has played an important role in modern industrial society, but its influence on human history stretches back 3600 years, as a fascinating post at the Lower Dover Field Journal makes clear.
