is an alpine species, which cannot have been native, if indeed it were 
ever found in any of the localities mentioned. 
SALIX RETUSA. Linn. 
Of the variety serpyllifolia of this plant, Fries states, that “beautiful 
specimens of the var. serpyllifolia are in Hornimann’s herbarium.” 
Mant. i. 76. SS. retusa is also said to have been found on Ben Lawers, 
but on the utterly unreliable authority of Dickson: Dickson, in his 
“ Fasciculus,” published garden specimens of Trichonema Bulbocodium 
to represent the Jersey T. Column, also cultivated specimens of 
Echium Italicum to represent the Jersey E. plantagineum. 
Sus-Ctass VI.—GYMNOSPERM A. 
Perianth none. Ovules naked, at least at the time of flowering, 
fertilised by the pollen falling directly on the ovule; ovules containing 
secondary embryo sacs (corpuscula), enclosed in the primary one, and 
with numerous embryos, only one of which, however, becomes fully 
developed. 
ORDER LXXIII—CONIFERA. 
Trees or shrubs, with the stem increasing by regular annual layers, 
destitute of ducts, and composed of woody cells marked on the sides 
with circular disks which have a central dot. Leaves scattered or 
opposite or in fascicles, generally acicular, rarely expanded and flat, in 
the latter case with the veins parallel. Flowers in catkins, moncecious 
or dicecious, destitute of perianth; the female catkins in fruit forming 
a strobile or cone, with woody scales, or a pulpy berrylike galbulus, 
with the scales coherent and fleshy, more rarely with the seed naked, 
surrounded at the base by a fleshy cupshaped arillus. Seed albu- 
minous. 
Sus-Orper I.—ABIETINEZ. 
Male flowers in catkins. Female flowers in a catkin, usually nume- 
rous, placed upon scales in the axils of bracts. Apex or opening of 
the ovules turned downwards. Fruit consisting of a cone, with woody 
or somewhat leathery scales.
