Frog orchid (Coeloglossum viride)

Description:
Green wolf's tongue and alpine cepetuljka - similarity:
Differentiating cuckoo orchids some call orchids (Orchidaceae) can be quite uncertain, solely by habitus or general appearance.
Green wolf's tongue and alpine cepetuljka we will easily confuse only by height of growth and color of the "helmet", that is 5 perianth leaves that "cover" the flower, while the 6th perianth leaf (the lower one of 3 from the inner circle) is significantly different – named honey lip. The helmet color is in both species very variable and similar from greenish, yellowish to reddish.
We can easily distinguish them by the following characteristics:
Green wolf's tongue - Coeloglossum viride (L.) Hartm.
The honey lip is strap-shaped – equally wide at the base as at the tip. At the tip it is split into 3 lobes, with the middle lobe distinctly smaller than the lateral ones, sometimes almost atrophied so we barely notice it, thus the honey lip can appear two-pronged (like a snake's tongue). In color it can be yellow to greenish-reddish.
The stem is smooth round and leafy at least with one (1) cauline leaf, otherwise there can be 3-6.
Leaves are flat lanceolate-ovate, at the tip ± pointed and clasping the stem like scissors. Basal ones are somewhat larger than the upper ones.
