Erzberger, Peter: The bulbilliferous species of Pohlia (Bryaceae, Musci) in Hungary

Key to the bulbilliferous species of Pohlia in Europe The following key is based essentially on SHAW (1981), LEWIS and SMITH (1978), NEBEL (2001) and NORDHORN-RICHTER (1982), with inclusion of P. flexuosa Harv. (syn. P. muyldermansii R. Wilczek et Demaret) based on DEMARET and ARTS (1983) and SMITH (2004). Typical bulbils of all species are shown in Figure 5. For detailed descriptions of the species and illustrations showing the range of variation reference should be made to these works, especially to SHAW (1981) and SMITH (2004). 1 Bulbils solitary in leaf axils in upper part of stem 2 1* Bulbils numerous in leaf axils at least in upper part of stem 4 2 Leaf primordia pale, usually forming a crown at the top of the bulbils, small, inconspicuous, comprising 1/5 (-1/3) of total bulbil length; bulbils ovoid, usually less than twice as long as wide, ripe up to 600 urn long, yellowish; leaves straight, appressed to erect when dry 2. Pohlia filum (Schimp.) Mârtensson (N America, N, C Europe, Asia; Fig. 5B) 2* Leaf primordia conspicuous, green, distributed over the whole bulbil surface or apical and then comprising ca 1/2 of total bulbil length 3 3 Bulbils oblong to cylindrical, usually at least twice as long as wide, ripe 450-1200 um x 270-500 urn, reddish-brown; leaf primordia green, acute, erect-patent, inserted from the base, rarely from the middle of the bulbil body; plants glossy, leaves flexuose, patent when dry 1. Pohlia drummondii (Müll. Hal.) A. L. Andrews (N America, N, C Europe, Asia; Fig. 5A) 3* Bulbils (including primordia) usually narrowed towards the apex and the base in outline, not larger than 600 urn, yellowish-green when young, red-brown when mature; leaf primordia 3-5(-8), laminate, erect, comprising ca 1/2 of total bulbil length, inserted at same level at flattened bulbil apex; plants glossy, leaves straight, appressed to erect when dry 7. Pohlia andalusica (Höhn.) Broth. (N America, W, C Europe, Asia; Fig. 5G) 4 All bulbils ± globose, hardly longer than wide 5 4* Bulbils oblong, obconic, or elongate and vermicular; sometimes ± globose, but then also elongate bulbils formed by the same plant (P. flexuosd) 7 5 Primordia of all bulbils broadly triangular-laminate, obtuse, reaching about 1/3 of total bulbil length, conspicuously concave, forming a dome over the
