OF FILAMENTOUS, FRUTICULOSE, AND FOLIACEOUS LICHENS. 167 
and Cape Horn, coll. by Dr Hooker, and in Herb. Hooker, Kew, seem to be the 
same plant, which is here spermogoniferous only. The ramules are frequently 
black, straggling, and very delicate. 
Specimen 5.—Pic d’Orizaba, Cordillera (Vera Cruz), Mexico, at an elevation of 
11,000 to 12,000 feet; coll. by H. Gateorri, 1840, No. 6906; also from the same 
locality, 1838, coll. by J. Linpen, No. 102; both in Herb. Hooker, Kew; sper- 
mogoniferous. 
Specimen 6.—ScHARER exs. 22, Switzerland ; associated with Cetraria 
islandica. The spermogones are large distinct barrels. 
Specimen 7.—Var. racemosa, Sch.; on old walls, Caerlaverock Road, Dumfries, 
August 1856, W. L. L. The podetia are dark-coloured, and are covered with 
furfuraceous granules, scales, or folioles, from base to apex. The spermogones are 
short, and sometimes so broad and subspherical as to resemble young apothecia. 
They crown the delicate ultimate ramuscles, which are lax and patent. The 
spermatia are chiefly straight, and about jth long. Some of the sterigmata are 
subarticulate, consisting of a few linear cells, placed in superposition, or branching 
off laterally in groups, in which case the sterigmata are very ramose, and some- 
what longer than usual. 
Specimen 8.—Var. racemosa; Le1GHTON exs. 16, Haughmond Hill, Shropshire ; 
a few apothecia. The spermogones are chiefly old, containing no free spermatia. 
The sterigmata are very irregular in form, and thickened. 
Specomen 9.—Var. racemosa; Sandhills, Newcastle, County Down, Ireland ; 
Professor Dicxiz. The plant is dwarf, deformed, and bears no apothecia. The 
Sspermogones are few, young, and contain no mature or free spermatia. 
Specomen 10.—Var. racemosa ; rocks, Mount Wellington, Van Dieman’s Land, 
Mossman, 1850; in Herb. Royal Botanic Garden, Edinburgh. Plant spermo- 
goniferous only. 
Specimen 11.—Var. racemosa; SCHERER exs. 80 (sub C. fruticosa a. racemosa) ; 
on the ground in woods, Switzerland ; also exs. 81 (0. furcata). In both, the sper- 
mogones have the usual characters. 
Specimen 12.—Schooley’s Mountains, North America, July 1856, Dr A. O. 
Bropiz. Spermogones have the characters of those of British plants or specimens. 
Specimen 13.—Singalelah, Sikkim, Himalaya, alpine region, at an elevation of 
11,000 feet; Chongtan, Sikkim, temperate region, at 8000 feet; Lachoong, Sikkim, 
temperate region, at 9000 feet—all collected by Dr Hooxer. Churraand Khasia, 
subtropical region, at 4000 feet; Kollong, Khasia, temperate region, at 5000 feet ; 
coll. by Drs Hooker and Tuos. Toomson ; all spermogoniferous, but bearing no apo- 
thecia. New Zealand, Dr Jotirre; thallus very white and delicate, and minutely 
scaly. St Domingo, ScHomBURGK; very pale, thin, delicate podetia. Jamaica; 4—6 
inches tall. Ohio, Lea; Cedar Swamp, near Urbana; spermogones abundant and 
distinct. Boston. Switzerland, near Chateat d’Oex. FRANKLIN’s first journey ;
