many of the common European species. The old Roman roads 
which still exist in the immediate neighbourhood of Algiers are 
rich’ in rare species: under the shade of the wild olive-trees 
which overhang these roads are found Lycopodium complanatum, 
Grammitis leptophylla, Asplenium palmatum, Trachelium caruleum, 
Campanula dichotoma, Sedum heptapetalum, Scrophularia trifoliata 
and mellifera, Allium triquetrum, many Ophryses, and other in- 
teresting plants, whilst the trees themselves are festooned with 
Clematis cirrhosa, which is covered with flower in December, 
Smilax mauritanica, Convolvulus sepium, wild vine, Tamus com- 
munis, Aristolochia altissima, Rosa sempervirens, and in some 
parts Ephedra altissima and Equisetum ranosissimuin. 
The province of Oran affords the richest harvest of rare plants, 
both on the coast and in the interior. In the sandy plaims of 
that province the Cynomorium coccineum is common, and in the 
brackish water lakes are found Durigza helicophylla and Ruppia 
trichodes, two new species of plants found by M. Durieu. Near 
Saida is found the curious Otocarpus virgatus, a new plant of the 
family of Cruciferae. This family has some very curious repre- 
sentatives in this province, and which are not found except in 
Algeria; such are Condylocarpus muricatus, Psychine stylosa, 
Lonchophora Capiomontiana, and Bunias prostrata. The greatest 
number of species of plants in Algeria may be reckoned in the 
family of Leguminose. The neighbourhood of Oran furnishes 
several new species of Genista, such as G. cephalantha,Spach, G. 
Duriai, Sp., G. spartioides, Sp., G. numidica, Sp., G. ulicina, Sp., 
G. atlantica, Sp., G. erioclada, Durieu, all of which are figured 
in the splendid work now publishing by the French government, 
upon the labours of the Scientific Commission sent to Algeria a 
few years ago to explore its productions in natural history. The | 
family of Leguminose also presents us with a number of species 
of Medicago, some of which are new, viz. M. corrugata, Dur., 
M. plagiospira, Dur., M. secundiflora, Dur., which are figured 
the work above-mentioned. In the same family we have some 
interesting plants amongst the pea tribe, such as Orobus atro- 
purpureus, Desf., which covers the meadows in certain localities 
on the plain of Mitidja near Algiers, and flowers in April. In 
my catalogue of the plants of Algiers I have described a new 
species of Lathyrus, under the name of L. luteus ; it climbs the 
hedges near Algiers, and resembles very much L. sylvestris, L., 
but its yellow flowers and filiform stipules constitute it a distinet 
species. . Lathyrus Clymenum and L. tingitanus, L., the latter of 
which is commonly cultivated in our gardens under the name of 
Tangier pea, are both very common in the hedges and brush- 
wood. 
Jt was my intention to have passed in review each family of
