albicans, Frullania dilatata, Radula complanatd) are anamy] and form no 



starch, either in assimilative or storing tissues. Their product of 

 assimilation is sugar, their reserve material principally fats. 



In the anamy 1 and saccharophyll mosses the suppression of the starch 

 formation may be regarded as an adaptation to xerophil conditions, which 

 is especially found among the more lowly organized lithophytes and 

 epiphytes. It is often associated with weakly developed conducting 

 tissue. Starch is richly developed in bryophytes which inhabit moist 

 situations, e.g. thalloid hepatics. Polytrichacese,. Bryaceae. Starch is 

 more densely stored in the terminal bud and vaginula, in the sexual 

 organs and sporogonium. And in such cases it takes the form of minute 

 grains. Large grains occur mostly in the form of leucoplasts in the 

 thallose liverworts. 



New Antitrichia.* — J. G-lowacM describes a new species of Anti- 

 trichia, A. pristioides, whicli he found in two localities in Montenegro at 

 a height of 1000 m. It is a stouter plant than A. curtipendula, the 

 growth is more upright, and the leaves are patent. The leaf-apex is 

 toothed : there are no accessory veins. Fruiting specimens from Hodza 

 near Sarajewo were of a deep brown colour, and the hexagonal cells of 

 the capsule epidermis showed radial stripes of straight lines of thickened 

 tissue on the outer capsule wall. The spores are almost twice as large as 

 in A. curtipendula. The plant grows on stems of red beech and fir. 



New Mosses from West Ross-shire.t — J. Stirton publishes descrip- 

 tions of six new mosses from West Boss-shire — namely, Gampylopus 

 Fergussoni, G. crenulatus, G. citrescens, Br yum rubicundum, Hypnum 

 intortum, and Gampylopus perplexans— all collected near Plockton in 

 1913. By way of introduction he calls attention to certain large cells of 

 moss leaves, which latterly have played an important part in the dis- 

 crimination of species. 1. Large oblong cells usually with thickish 

 walls, either pale or becoming more or less red or brown and then 

 opaque, situated at the base of the leaf either next the margin — the 

 usual situation of the auricles — or next the nerve, situated almost always 

 in the centre of the leaf. 2. Elongato-hexagonal cells with thin walls, 

 in double layers — that is, one layer of cells on the anterior surface, 

 the other just behind the first (as shown by thin transverse sections of the 

 lower part of the leaf). The position of these groups is either at the 

 alar margin or at the middle base. 3. Another cell plays nearly as 

 important a part as the other, although it is seldom or never seen quite 

 at the base of a leaf. viz. the fusiform, either hyaline or filled with 

 granules, or a modification of it (the more frequent), viz. undulating or 

 sigmoid in place of straight throughout. 



Moss Flora of Carinthia.J — K. Prokaska records his investigations 

 in the Lower Gailthal, and gives a list of the mosses and hepatics. No 

 new species are described. In specimens of Alicularia scalaris, he found
