A view to the northwest from within Dun Aonghasa in springtime. The interior a karst formation (see my post, ” Galway Bay View from Dún Aonghasa”), the grikes filled with grass and a sprinkling of white and yellow flowers, a cloudscape rising over the walls. Inishmore, Aran Islands, County Galway, Ireland.
Karst Landscape with Interior Walls of Dun Aonghasa
The exposed limestone of the Aran Islands here transitions to a fertile field of grass, husbanded by generations of islanders. Photograph was taken from the path on Inishmore leading up to Dun Aonghasa.
The Aran Islands are an extension of The Burren of Ireland’s Counties Claire and Galway. The word burren is from the Irish Boireann, meaning “great rock.” The glaciers that covered Ireland, retreating about 10,000 years ago, scraped down to the bedrock, exposing wide areas of limestone and dropping, here and there, large rocks. When people came along the foreign nature of the large rocks was recognized, all the more obvious for lying on the horizontally bedded, exposed limestone. We call the foreign rocks erratics. The underlying scoured rock is a pavement for a resemblance to a cobbled roadway.
The incised line, filled with grass and wildflowers, in the following photograph is called a gryke. The body of stone between the grykes are clints. Sometimes, the grykes are cross hatched and the clints resemble cobblestones or flat paving stones.
The view is northeast toward the 12 Bens of Connemara. Inishmore, Aran Islands, County Galway, Ireland
Modern stonework borders the 1/2 mile path to the inner Dún Aonghasa walls, keeping tourists off delicate plants, maintaining the integrity of this ancient site.

I found these snags surrounded and, at a distance, hidden by the burgeoning Brock-Harvey forest preserve here in the Finger Lakes.
As with burgeon (see yesterday’s blog post), the word “snag” has a long history from a forested northern region of the planet, though it hales from Scandinavian languages rather than Old English and Old German. As a noun “snag” is something with a point and a body long enough to cause inconvenience, the point catching on anything handy. As a verb “snag” is to become inconvenienced by a projecting body.
In forestry, a snag is any trunk of a dead tree. Commonly, a tree top breaks off leaving a jagged point which possibly can become an inconvenience. For birds, an upright dead tree is a blessing, perfect for homemaking.

Fallen, the snag is still a snag and also a home first for fungus. When the work of the fungus is done, the resulting mound is perfect for growing new trees.
There is a word to describe the first growth of spring, rare in a way as having grown within the English/French languages without roots from either Greek or Latin, wholly suitable to a forest people. The first growth of spring so impressive it has words of its own: burgeon.
Both as a noun, burgeon the bud itself, and a verb; to burgeon, as in to burst forth. Burgeoning: the process of the act itself.
Questions about speciation of flora can be complex and are so in the case of trillium. A straightforward answer is “yes,” white and red trillium are different species with distinct characteristics, as can be seen from the first photograph.
The white trillium below are in the species Trillium grandiflorum as evidenced by coloration, the shapes of the flower petals and anthers. For this discussion I will focus on the flower petal shape and coloration. The grandiflorum petals are broad at the base and wavy, compared to the more blade-like red trillium, Trillium erectum, straight-edged petals.
There is the obvious difference of color, but Trillium erectum has a white form, not seen here.

Then, there is this specimen, below, with a stippling of red on blade-like petals with wavy edges. Here is where the experts differ and, in summary, many believe trillium species are an interrelated complex with the possibility of hybridization, sharing of genetic material between the different species to produce fertile offspring. This specimen may be an example of this hybridization.
