(Warming, ' Bestovningsmaade,' p. 44, Bet. Tids., Kjobenhavn, xvii, 1890, pp. 218-19.)—On the Dovrefjeld, according to Warming, the fragrant flowers of this species possess a mechanism similar to that of P. lapponica, but the style does not project so far from the upper lip. 2162. P. flammea L. (Warming, ' Bestovningsmaade,' p. 47 ; Abromeit, op. cit.)—Warming states that in this species, on the Dovrefjeld, the style is always enclosed in the upper lip, the stigma being just above the anthers, so that self- jX)llination easily takes place. He observed the formation of fruits. For Greenland Abromeit describes the corolla as 12-14 mni- long, yellow in colour at the base and in the middle, and with a brown-red upper lip. Fruits were observed to be set on the Karajak nunatak (17. 7. '93).. Fig. ,^ii. Pedicularis hirsuta, L. (after E. Warming). A. Flower seen from the side. B. Do., from the front. C. Style with stigma.
