apex that often traps an air bubble; bulbils 230-400 um x 100-230 um, (green) yellow-orange (red), according to age; plants glossy 3. Pohlia bulbifera (Warnst.) Warnst. (N America, N, C Europe, Asia; Fig. 5C) 5* Primordia of some or all bulbils short and peg-like, often incurved over the apex, but not forming a complete dome 6 6 Plants glossy when dry; bulbils red-translucent, rarely more than three times as long as wide, typically 50-165 urn long, primordia inconspicuous, developing from short, peg-like protuberances to laminate outgrowths 4. Pohlia andrewsii A. J. Shaw (N America, arctic-alpine Europe; Fig. 5D) 6* Plants dull when dry; bulbils yellow-translucent, occasionally brown, globose to slightly elongate but rarely more than twice as long as wide, mostly (70-)80-130(-175) um x 60-110(-150) urn, usually stipitate, leaf primordia poorly formed, peg-like, incurved, consisting of only l(-2) cells, never laminate 5. Pohlia camptotrachela (Renauld et Cardot) Broth. (N America, W, N Europe; Fig. 5E) 7 Leaf primordia distinctly laminate in form; plants glossy 8 7* Leaf primordia peg-like, rarely becoming laminate on very large ovate bulbils; plants dull or glossy 9 8 Bulbils linear-cylindrical 6. Pohlia tundrae A. J. Shaw (W North America, Austrian Alps; Fig. 5F) 8* Bulbils obconic to oblong-bulbiform 7. Pohlia andalusica (see above) 9 Plants glossy when dry 10 9* Plants dull when dry, bulbils variable in shape and size 11 10 Bulbils usually less than 120 urn long, variable in shape and size, leaf primordia developing from 1-cellular stages into laminate outgrowths 4. Pohlia andrewsii (see above) 10* Bulbils mostly 150-300(— 450) urn long and to 60 urn wide, rather uniform in shape, oblong-linear to linear-vermicular, green, yellow, orange, red, according to age; leaf primordia 1-2, reaching 1/4 of total bulbil length 9. Pohlia proligera (Breidl.) Lindb. ex Arnell (N America, Europe; Fig. 5J) 11 Leaves patent in the dry state; leaf cells uniformly wide from costa to margin; bulbils opaque, with (2-)3-4(-5) peg-like, erect primordia (occasionally becoming laminate with age), bulbils extremely variable in size and shape, obovate, obconic to elongate and narrowly turbinate, occasionally bulbiform, rarely vermicular, different forms often present on a single stem, mostly more than 80 urn wide at the broadest point and 150-300(-550) urn long, green, yellow, orange, red, according to age 8. Pohlia annotina (Hedw.) Lindb. (N America, N Asia, Europe; Fig. 5H, I)
