BRYOLOGICAL NOTES 339 



The most distinct of these is the last, L. Curdleana, which is 

 Australian ; those numbered 4-7 are, so far as known, exclusively 

 African ; Nos. 1 and 3 are very widely distributed, but No. 3, 

 L. aqiiatica, in the restricted sense, appears to be rare in South 

 Africa ; No. 2 refers to a North Bohemian plant, of which I have 

 not seen the type, and which perhaps it is not worth trying to dis- 

 tinguish from No. 1, L. mhulata Ives, the form principally con- 

 sidered in this article. 



In some forms of L. aqiiatica the stem is developed so as to pro- 

 duce on it alternate leaves and axillary flowers ; these forms have 

 been called var. caulescens Koch in Uohlmg' s DeutscJdands Flora, iv. 

 p. 425 (1833) ; corresponding caulescent forms occur also on some 

 of the African species. 



The figure (Plate 426 C) was taken from one of the young 

 June specimens, and scarcely represents the mature plant in a satis- 

 factory manner. Fig. 4 represents a detached flower magnified 

 six diameters, and shows the pistil seen through the transparent 

 floral envelopes.

(15) Philocrya Hagen & Jensen. 



In 1898, in Meddel. om Gronland, xv. p. 388, Hagen and Jensen 

 described and figured a moss from Greenland, under the name of 

 Philocrya aspera, as the type of a new genus of Polytrichacem. The 

 following generic characters are given : — "FoHa rigida, brunneo- 

 fusca ; costa angusta ; alis laminae non lamelligeris, juxta costam 

 bi- deinde unistratis, ad margines hi- tristratis." The authors add 

 the remark: " Multis dubiis versati genus hoc novum ad plantam 

 perfecte sterilem instituimus. Sed characteres a foliis allati ita 

 sunt graves, ut, etiamsi fructus essent cogniti, tamen nullo cum 

 familige genere conjungi posset. A Polytricho, Polytrichadelpho, 

 Pogonato enim longe distat costa angusta, ea tantum lamellosa, et 

 structura alarum foliorum ; ab Oligotricho, Psi/opilo, Catharinea, 

 non minus distinctura est et habitu eximie polytrichaceo et alis 

 majore parte bi- vel tristratis." In 1900, in Journ. Linn. Soc. 

 Lond. (Bot.) xxxiv. 464, pi. 17, f. 20, I made some notes on the 

 Atriclmm Lescurii of James (Bull. Torr. Bot. Club, vi. p. 33 (1875) ) — 

 OUgotrichum Lescurii Mitten — and remarked : " The generic position 

 of 0. Lescurii still remains, perhaps, a little doubtful." After 

 describing and figuring the leaf-structure, I added: "This type 

 of leaf is anomalous for both Atrichum and Oliyotrichum, and is 

 most nearly approached in certain species of Polytrichum, from 

 which genus, however, the glabrous calyptra and the position and 

 structure of the lamellae separate the present plant."
