2. ALIBREXIA tomentosa. Alona tomentosa, Lindl. Bot. Reg. 
1844, sub. tab. 46.—prostrata: foliis lineari-oblongis, spa- 
thulatis, confertis, incano-tomentosis; floribus solitariis, 
calyce tomento aurantiaco utrinque vestito, laciniis 3-an- 
gularibus, erectis, corolla pubescenti, alba.—Chile, Valpa- 
raiso.—(v. s. in herb. Hooker. Cuming, n. 121. 241. 
Bridges, n. 481. 328.) 
This species also grows on maritime rocks, and is distin- 
guished by its longer, broader (in proportion to their length) 
and more incanous leaves, by its corolla not quite so fleshy 
and whiter. The leaves are sometimes 13 lines long, and 
nearly 2 lines broad, densely covered with short white branch- 
ing almost stellate hairs, the base of the petiole is enlarged, 
and adheres to the stem by a concave pulvinate gland, which 
is almost glabrous, and much more conspicuous than in the 
last mentioned species: the calyx is covered, within and 
without, by a dense orange coloured tomentum, and its 
lobes are broader and more triangular.

tab. 113. (male depicta). Alona revoluta Lindl. Bot. Mag. 
1844, p. 46.—prostrata, incana, stellato-tomentosa, ramulis 
plurimis succosis; foliis geminis, lanceolatis, spathulatis, 
carnosulis, margine revolutis; floribus solitariis, axillari- 
bus, ceruleis.—Peruvia, v. s. in herb. Hooker: locis maritimis 
Lurin, Mathews, n. 836—837. Cuming, n. 1068. 
This plant grows on the sandy beach at Lurin in the 
harbour of Callao, and also in the province of Camana, 
whence it was sent to Ruiz and Pavon by Tafalla, together 
with the drawing above cited, which affords a very imperfect 
representation of the flower: it is quite prostrate, with many 
short, slender, radiant branchlets which are woody towards 
the base, fleshy towards the extremity: the leaves are about 
1 or 14 inch long, and about two lines broad, the peduncle is
