times with L. sympagea. Occasionally very narrow and very deep 

 orange forms of Physcia parietina occur a foot and a half heloio 

 the zone of Lichina confinis. On the rocks a little higher up were 

 Bamalina scojMlorum, its var. incrassata, and B. cusindata; while 

 still higher were extensive sheets of Lecanora parella, with 

 angular apothecia on account of their crowdedness ; L. atra was 

 less abundant than usual, and L. ferruginea f. cestiva occurred in 

 a scattered manner. 



On some of the moorlands near Lerwick Calluna was both 

 larger and more abundant than in Unst and about Ollaberry ; 

 Anthoxanthum and Aira flexuosa were also in greater quantity. 

 There seemed to be much less Sphagnum and Scabiosa succisa. 

 Bhacomitrium lanuginosum was not a great feature, except in 

 places which receive a driving wind at two hundred or more feet 

 elevation. 



The schistose rocks that were much exposed had on them 

 plenty of Lecanora parella var. gyrocheila, Lecidea rivulosa, 

 L. contigua. The rocks lower down, about which gulls congregate, 

 have usually a different flora ; some had abundance of the nitro- 

 philous Physcia lychnea, whilst others were covered with a small 

 species of that still more nitrophilous genus Prasiola.

SoLANUM tetrandrum R. Br. var. angustifolium var. nov. A 

 typo discrepans praesertim ob folia anguste oblongo-lanceolata. 



A slender soft-wooded shrub of 3 or 4 ft., without prickles, but 

 covered with a dense tomentum of stellate scales, and answering 

 generally to the description of S. tetrandrum R. Br. The leaves, 

 however, are not ovate, but narrow oblong-lanceolate, closely in- 

 duplicate and recurved at the top, without lobes, and measuring 

 6-8 cm. X 0-4-0-7 cm. Both calyx and corolla are cleft very 

 irregularly, but the corolla less deeply, so that the lobes are 

 shorter and broader than described. The stamens, so far from 

 being only four in number, are sometimes six.

[* See pp. 164-168. Calandrinia Creethce (p. 165) is there first published ; 

 it should be cited as of Morrison, as only the name was suggested by Dr. 

 Tratman. Indigofera boviperda (p. 166) was mentioned but not described in 

 a report by E. A. Mann, Government Analyst, on the chemical composition 

 of the plant, in the Journal of Agriculture of IT. Australia, xiii. 28 (1908), —
