Broadleaf footlock (Dactylorhiza majalis, Orchis latifolia)

Momentum 10-90 cm h., straight, usually strong, wind-blown, nieco kanciasty, green or purple to purple above.

Broadleaf footprint flower (Dactylorhiza majalis ssp. majalis) a – upper outer lobe of the perianth, b – internal side, c – lateral external, d – warżka, e – ovule and spur, f – hypophysis.

Leaves 2-7, 4-25 cm length, 0,5-6 cm times., from lanceolate to ovate, lowest blunt, higher spicy, highest change, pituitary, green, usually spotted, less often smooth, dirty red spots, faded to deep purple. Inflorescence 3-12 cm length, usually dense, multiflorous, less often loose, stingy.

Pituitary gland usually 20-30 mm length, 3-6 mm width, lancetowata, spicy, slightly arched, green with a purple edge, sometimes all dark red or blotchy.

Ovary 10-12 mm length, slightly arched, twisted, green to purple.

Warżka 6-12 mm length, 9-14 mm width, transversely oval, clearly 3 patches, with side patches folded back, usually red to purple, often with a lighter throat, covered with dark lines and spots; the middle patch is longer than the side ones, narrow, tongue-wad, blunt; large side patches, rhombic to ovate, karbowane. Ostroga 5-12 mm length, stożkowato-cylindryczna, blunt, straight or slightly bent, pink to purple with a pale base.

Upper outer petal 8-10 mm length, 3—4 mm wide, ovoid lancet, blunt, pink to purple, usually with darker spots. Lateral outer petals slightly longer, ovoid-lanceolate, sharp or blunt, asymmetric, arched backwards, similar color as above.

Lateral inner petals 6-8 mm length, 2-3 mm width, ovoid-lanceolate, blunt, otherwise like the previous ones.

The column 4-5 mm length, pale pink to purple, green-gray pollinia.

Fruit to 15 mm length, rotund.

Just like the previous one, it is a very changeable species, both in terms of lip shape, leaves, and habit.

The key to identifying subspecies

1. Leaves 2-4 times longer than wider, of jajowato- for broad-legged cetaceans, spread wide, strong plant……………

ssp. majalis

1. Leaves over 6 times longer than wider, lanceolate to even narrow, slender plants …. 2

2. Slender plants, do 20(25) cm h., leaves 6-8 times longer than wider, grow old on the side, collected in a rosette at the base of the shoot, inflorescence 3-4 cm length, loose and sparse-floral ………………

ssp. hrevifolia (Bisse) Sengh.

2. Plants 25-70 cm h., leaves 8-10 times longer than wider, almost vertical, inflorescence 3-6 cm length, gestures, multiflorous ………………….

ssp. baltica (The blade) Sengh.

The most common of the above-mentioned is the typical broadleaf footprint (ssp. majalis). It occurs all over Poland, differentiating into a number of varieties and races. Mainly fertile, calcareous meadows and peat bogs. Baltic alloy (D. majalis ssp. baltica (The blade) Sengh.) grows only in the northern part of the country, in Pomerania, Masuria and the Suwałki region. In addition, it was served from the northern part of Russia, Northeast Germany and Scandinavia. It occurs in similar habitats as the previous one, more often in salty coastal meadows. Closely related to the Baltic lockpiece is Ruthe's lockpiece (Dactylorhiza majalis ssp. baltica var. ruthei (Schulze) Shit.), described from the vicinity of Świnoujście, and considered endemic in our old botanical literature. As recent research shows, it is only a local variation of the Baltic footprint, the only difference is the lack of spots on the leaves and the lighter color of the flowers. The last of the subspecies of the broadleaf footprint (D. majalis ssp. brevifolia (Bisse) Sengh.) so far only found in Pomerania. Outside our country, it grows in southern Sweden, Denmark and the north-eastern part of Germany. It occurs in coastal meadows.

The growing season begins, usually at the turn of March and April. It blooms most often in May and early June. A month later it bears fruit. The growing season ends in July to September.
