Bee Orchid Ophrys apifera mutations, variations and aberrant forms


Bee Orchid Ophrys apifera (Fr. Ophrys abeille) has a wide European distribution and frequently self-fertilises. This is thought to be the reason it produces so many varieties and aberrant forms. The species flowers in June, producing spikes of 3 - 10 flowers about 25mm across, from a rosette of leaves. The sepals are normally bright pink and the labellum formed from one larger rounded brown 'tongue' with two smaller velvety lobes which stick out at either side. They grow in grasslands of all sorts, from lawn to rough scrubby hillsides. For the full species account click here.

Normal Bee Orchid Ophrys apifera var apifera. Petals shorter than a quarter the length of the sepals. (The sepals are the three bright pink bits at the back, the petals are the two little reddish green bits at the junction of the sepals near the centre.)

Ophrys apifera var flavescens. The labellum (tongue) is yellow. This is a mutation known as hypochromatism (lacking colour), where the orchid has lost all red pigmentation and is pale.

Bee Orchid Ophrys apifera var curviflora. Indre et Loire. Photo by Susan Walter.
Ophrys apifera var curviflora. The labellum is concave and the appendix at the tip (like a little yellow tongue) is visible. Normally this curves the other way, up behind the labellum, and the labellum itself is convex.

More aberrations and variations will be added as I encounter them.

European Birthwort Aristolochia clematitis




Scientific Name: Aristolochia clematitis (Aristolochiaceae). 'Aristolochia' means 'best childbirth' and 'clematitis' means 'clematis-like'.

English Name: European Birthwort (Birthwort family).

French Name: Aristoloche clématite (='clematis birthwort').


5 Key Characters:
  • twining plant that will creep over and climb up surrounding vegetation to about 80 cm.
  • leaves large (up to 10 cm across) and heart shaped.
  • flowers rather small and inconspicuous, pale yellow, but a distinctive trumpet shape.
  • unpleasant smell.
  • seedpods fat, pear shaped, hanging.

Lookalikes:

Habitat: Dry, hot, alkaline soil, rocky or sandy places, in vineyards.

Flowering Period: May-June-July-August-September.

Status: Widespread but uncommon. John Robertson points out on The Poison Garden that this is one of the most poisonous plants and has probably caused more harm than any other, partly due to the mistaken belief in the Doctrine of Signatures which led to a plant with a uterus shaped flower being prescribed by herbalists for childbirth. In fact it leads to renal failure and urinary tract cancer. It has also caused similar problems in modern times when the seeds of this and related species contaminate cereals or are included in traditional Chinese medicines.

Strapwort Corrigiola litoralis




Scientific Name: Corrigiola litoralis (Caryophyllaceae).

English Name: Strapwort (Carnation family).

Habitat: Sandy gravel banks in lowland rivers with fluctuating water levels (exposed in summer, flooded in winter). Farm tracks, rural footpaths. Requires the habitat to be disturbed (eg by cattle trampling).


Flowering Period: June-July-August-September.


Status: Uncommon. Can be threatened if water levels stabilised, or if plants such as Common Reed Phragmites australis or Common Nettle Urtica dioica take over the habitat. It can't compete with other taller plants in the vicinity. Its presence on the Loire River sands reflects the river's connection with the Atlantic seabord.

Soapwort Saponaria officinalis




Scientific Name: Saponaria officinalis (Caryophyllaceae). The specific name 'officinalis' indicates that the plant had a use, often medicinal, but can be culinary or other (in this case the plant can be used like soap).


English Name: Soapwort (Campion family). Also Bouncing Bet; Crow Soap; Wild Sweet William; Soapweed; Boston Pink. The suffix 'wort' (pronounced to rhyme with 'Bert' not 'wart')  indicates that the plant has a traditional use, usually medical, but can be culinary or other (in this case, the plant can be used like soap).


French Name: La Saponaire officinale (='medicinal/working suds maker'); also la Savonnaire (='soap maker'), la Savonnière (='soap maker'), la Saponière (='suds maker'), l'Herbe à savon (='soap plant'), l'Herbe à foulon (='fulling plant'), le Savon des fossés (='ditches' soap'), le Savon de fosse (='ditch soap').


5 Key Characters:

The stamens of the flower on the right has been 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.

White Mulberry Morus alba




Scientific Name: Morus alba (Moraceae).

English Name: White Mulberry (Mulberry family).

French Name: Mûrier blanc (='white mulberry tree').


5 Key Characters:
  • small to medium sized tree.

  • leaves pale and thin.
  • deciduous.
  • fruit can be white, pink or deep purple, sweet and bland, July - September.

Lookalikes: Black Mulberry M. nigra, which has darker, thicker leaves all of one shape.


Habitat: The banks of the Loire, close to the old silkworm production areas and troglodyte caves which were used in the industry.

Flowering Period: April-May.


Status: Widely cultivated in the past for the production of silkworms in the Loire Valley. Now an uncommon naturalised non-native in the wild.

  • rootless (attaches to host plant with a sucker) and entirely parasitic, especially on heather, gorse, clover, and members of the solanum (potato) family.
  • leafless (leaves reduced to tiny scales).

Lookalikes:

Habitat: Parasitic on a wide range of low growing plants, ultimately relying on disturbance of habitats to enable germination of seeds over long periods of time (disturbance is often in the form of regular management of a site).

Flowering Period: June-July-August-September.

Status: Locally common.

Beech Fagus sylvaticus




Scientific Name: Fagus sylvatica (Fagaceae).

English Name: Beech (Beech family).


French Name: Hêtre.


5 Key Characters:
  • large deciduous tree (30 m + high).
  • smooth grey bark.
  • red-brown cigar shaped buds.
  • oval barely toothed leaves 4 - 9 cm long, coming to a point, on stalks, with obvious veins at the edges.
  • edges and veins underneath leaves with soft fine hairs. 

Lookalikes: Young leaves easy to mistake for Hornbeam Carpinus betulinus, but Hornbeam has jaggedly serrated leaves. Hornbeam has winged tassle like seed capsules, Beech has nuts enclosed in a scaly woody cup. Hornbeam is considerably more abundant in this area.


Habitat: Damp chalk, limestone, sandy or loamy woodlands.


Flowering Period: April-May (seed September-October).


Status: Uncommon and localised. Some parcels of mixed Beech and Sessile Oak Quercus petraea can be found around the Pas aux ânes and Carrefour du Conservateur in the Forest of Loches. The odd isolated mature tree in Downy Oak Q. pubescens woodland near Panzoult. Sometimes planted as a specimen tree in chateaux parks, but essentially the climate in the Touraine Loire Valley is slightly too hot and dry for Beech to thrive. Although widespread throughout France, there is a striking lacuna in the national distribution map, for the départements of Indre et Loire and Loir et Cher (and on the Mediterranean plain), where the species is rarely recorded.
