FROM THE ANDES. 199 
THYSANANTHUS, Lindgb. 
1. T. Mexicanus, Tayl. Caule laxe cæspitoso, subflexuoso, 
ramoso; foliis imbricatis, patentibus, oblongis, acutiusculis, 
apice incurvis, integerrimis, lobulo obliquo, ovato, in laminam 
subdentatam folio applicatam desinente; stipulis tenuibus, 
rotundatis, integerrimis ; calyce axillari, oblongo, trigono, levi. 
On Pichincha. Prof. W. Jameson. Feb., 1847. 
Stems brown, loosely entangled. Leaves with large cellules, 
decurrent from the top of the lobule; the perichætial minute, 
erect. Pedicel as long as the calyx. Capsule spherical, at length 
dehiscing into four erect valves. Calyx flat and grooved above, 
and having an obtuse carina beneath, destitute of any margination, 
the base very narrow. Allied to our T. anguiformis from New 
Zealand; the stems and branches are longer, the leaves not so 
crowded, the calyx is destitute of angles, nor is if crowned with a 
tube as in that species; the stipules, too, are more round. 
LEJEUNIA, Libert. 
l. L. epibrya, Tayl. Caule implexo, procumbente, vage ramoso, 
subfasciculato ; foliis imbricatis, patenti-recurvis, oblongis, acu- 
tiusculis, integerrimis, lobulo oblique ovato quam folio suo 
duplo breviori; stipulis rotundato-ovatis, bifidis, sinu obtuso ; 
calyce axillari, obovato, levi, basi nudo, ore mucronato. 
On Mosses: on Pichincha. Prof. W. Jameson. Feb., 1847. 
Patches minute, yellowish-green. Stems four to five lines long. 
Leaves loosely imbricated ; the perichætial distant from the base 
of the calyx, erect, obovate, their lobule minute, the stipules with | 
acuminate segments. Pedicels divided by opaque projecting 
septa. Calyx destitute of angles or wings. This has a strong 
resemblance to L. serpyllifolia, Lib. ; yet the cellules of the leaves 
are much larger, the leaves are longer and more recurved, the sti- 
pules larger, the calyx smooth, and naked at its base.
