On Saturday 13 September the Association de Botanique et de Mycologie de Sainte Maure de Touraine met at Berthenay, a village on the left bank of the Loire River, on that spit of land which divides the Cher and the Loire before they unite near Villandry and Cinq Mars la Pile. There are several large sand islands in the river at Berthenay, and our objective was to investigate the flora of the Loire sands. Getting there involved me wending my way for an hour and a half via wiggly rural roads from Preuilly sur Claise
to Le Grand Pressigny
, on to La Celle Saint Avant and Sainte Maure de Touraine
, hang a left at the big roundabout and through Noyant en Touraine, Saint Epain and Villaines les Rochers
(I noticed there's a hemp crop on the outskirts of the basket weavers village) to Azay le Rideau
, then it's Villandry
, Savonnieres, cross the Cher and finally reach Berthenay.
Restaurant botanique in Berthanay.
Our meeting place was the church, which is right next door to a restaurant which bills itself as the Restaurant at the end of the World. It's run by a botanically inclined chef, who emerged from the restaurant and accompanied us on our outing.
Healthy Soapwort flower on the left, with normal pale stamens; infected by a fungus on the right, with dark stamens.
Even before we had left the restaurant garden Dominique was pointing out an interesting feature of the Soapwort Saponaria officinalis
planted there. The stamens were infected with a fungus, turning the pollen dark and compromising its functioning. The infected plant doesn't die though, as it will spread by runners as well.
The banks of the Loire are an extraordinary mix of invasive aliens (Chinese Mugwort Artemisia verlotiarum
; Thorn-apple Datura stromonium
; Jimsonweed Bidens frondosa
; Water Primrose Ludwigia
spp; Chufa Sedge Cyperus esculentus
) and rather rare and discreet plants, many of which are normally only found at the coast and reflect the Loire's connection to the Atlantic seabord (Red Bartsia Odontites vernus litoralis
; Marsh Woundwort Stachys palustris
; Strapwort Corrigiola litoralis
; Sea Aster Aster tripolium
White Mulberry Morus alba.
One of the introduced plants is a relict of the silk industry, introduced to the Loire in medieval times as the food plant for silkworms. White mulberry can be distinguished from its close cousin Black Mulberry M. nigra
by its paler thinner leaves which have many different forms on the one tree. White Mulberry fruit is pale and not interesting to eat, but silkworms thrive on the leaves.
The leaf beetle Chrysolina menthastri.
I found this lovely leaf beetle on a well munched leaf of Marsh Woundwort. I assume it is C. menthastri
as it looks right and is on the right sort of plant ie Laminaceae Mint family.
Female Long-winged Conehead Conocephalus discolor.
There were dozens of Long-winged Coneheads in the thick Paspalum
sp grass (another introduced plant) growing in damper patches on the sands.

A la cuisine hier: Pasta sauce, slow cooked chopped tomatoes from the Aged Orchard Neighbour, and our own homegrown peppers, chilli, aubergine, onion and garlic. Mostly frozen, but some used on a pizza with homemade dough topped with chorizo, mozzarella and parmesan cheese.
"...there's a hemp crop on the outskirts of the basket weavers village"...
so that's how they get the wiggly lines into the basket designs 8-()...
