Visiting Scotland-- a bit of wild Shetland

Last May I visited the Shetlands on a tour with Academic Arrangements Abroad and the Met. The northmost part of Scotland, they are beautiful!

Shetland, Scotland

First I looked out at the stunning view above, then down at the grass. Here you see plantains, Plantago lanceolata, flowering in the grass (blog on plantains).

Plant story: The amazing dioecious buffalo grass, Buchloë dactyloides

Buffalo grass, Buchloë dactyloides' (or Bouteloua dactyloides) [previous posts on buffalo grass and bison; drought tolerance, name] is a short drought-tolerant native American grass. It was one of the dominant (most common) grasses of the American high plains with a broad range from Mexico to Canada across our driest grasslands. It is highly regarded as food for cattle and bison. It is now being widely planted as a water-efficient lawn grass.

The success of buffalo grass is the more amazing to me because buffalo grass is dioecious. Dioecious means that there are male plants and female plants that have to mate before a seed is produced.

Plant Story - American Squashes

Sorting out the squashes is a job for experts, which I am not. They are wonderfully confused.

“True squashes” are plants in the genus Cucurbita (Cucurbitaceae, cucumber family). About 15 species make up Cucurbita, all of them native to the Americas. 

Melons, such as cantalope genus Cucumis, watermelon, genus Citrullus (blog about watermelon) and others--all the melons--are from Asia, Africa or Europe.

Visiting Dali, China--Among the Rice Fields


rice

At the end of September in 2013, I came into Dali in Yunnan (southwestern China), just as the rice was about to be harvested. I was on an Art in China tour with the Asian Art Association of the Denver Art Museum (coordinated by Access China Tours). (I wrote a blog giving an overview of the trip: see overview blog). China is famous for its rice, but in fact rice is grown only in the southern half of China. Historically the north grew millet, now it grows corn (maize). Here in southern China, however, rice is king.

Some botanists retire to garden, some retire to travel…Dr. Jane Bock retired to investigate crimes.  

She is a forensic botanist, one of a small group of experts who use their a knowledge of plants to help solve crimes. 

How can plants reveal the truth? It turns out there are many ways.

Visiting New Mexico -- Kasha-Katuwe Tent Rocks National Monument near Santa Fe

Our friend Sue Baum, spending six weeks in Santa Fe taking pottery classes at Santa Fe Clay, was told not to miss the Kasha-Katuwe Tent Rocks, so we happily went along on her visit. The directions from Santa Fe were clear and the distance not far, but we still managed to take a series of wrong turns (picture below). On the trip back to Santa Fe we got it right the first time!

Tent Rocks was worth the wrong turns we made before finding it.

There were strange and impressive formations, a combination of rock and sand, variously eroded. Kasha-Katuwe means "white cliffs" in the Keresan language of nearby Pueblo de Cochiti. Layers of volcanic deposits alternate, the harder layers protecting the softer from erosion.
