OF ORNAMENTAL PERENNIALS. 153 
1.— OROBUS LATHYROIDES, Lin. THE LATHYRUS-LIKE BITTER VETCH. 
Engriting. — Bot. Mag. t. 2098. 
Specific Character. — Plant Bmoothish. Leaflets ovate, mucro- 
nate, with divaricate nerves. Stipules semi-sagittate, a little toothed, 
smaller than the leaflets. Peduncles many-flowered, axillary, ahout 
equal in length to the leaves. Calycine teeth shorter than the tube. 
Legumes compressed, glabrous. Two or three-seeded. (G. Don.) 
Description, &c. — This species has a great number of small blue flowers crowded together, several racemes 
together ; with broad shining leaflets, and black roots. A native of Siberia ; introduced in 1758. 
2.— OROBUS FISCHERI, Swt. PROFESSOR FISCHERS OROBUS. 
Engraving.— Swt. Brit. Flow. Card. t. 289. 
Specific Character. — Steoi tetragonal, almost simple, smoothish. 
Leaflets linear, bluntish, mucronulate, nerved lengthwise, rather silky 
beneath. Stipules linear, acute, a little toothed, with one auricle at 
the base. Racemes pedunculate, many-flowered. Flowers secund. 
Legumes reticulatcly veined, six or seven seeded. (G. Don.) 
Description, &c.-^Thi8 species closely resembles 0. atropurpureus in its flowers, but its leaves are somewhat 
different. It is a native of Siberia, whence it was introduced in 1827. 
3.— OROBUS HIRSUTUS, Lin. THE HAIRY OROBUS, OR BITTER VETCH. 
SvNONVME. — O. laxiflorus, Desf. 
Engravings. — Bot. Mag. t. 2845 ; and om fig, 4 in Plate 36. 
Specific Character. — Plant hairy ; leaflets ovate, acute, with 
parallel nerves ; stipules unequally sagittate, lanceolate, about the size 
of the leaflets ; racemes axillary, few-flowered, longer than the leaves ; 
calycine segments nearly equal, setaceously-subulate, much longer than 
the tube, but much shorter than the corolla ; legume compressed, 
hairy. (G. Don.) 
Description, &c. — The flowers of this species are much larger than those of most of the other species of the 
genus. The leaves have each a single pair of leaflets, and the stipules are very large. The pods are very small, 
and hairy ; indeed the whole plant is covered with soft hairs, and hence the specific name. The species is a 
native of the Levant, and the whole of the provinces near Mount Caucasus, whence it was introduced in 1822. 
It is quite hardy ; and, as it ripens its seeds perfectly, it is generally propagated by them. It flowers in May. 
4.— OROBUS VERNUS, Lin. SPRING BITTER VETCH. 
EHGRAvrao.-~-Bot. Mag. 521. 
Specific Character. — Stem simple, flexuous; leaflets ovate, lanceo- 
late, nerved lengthwise ; stipules semi-sagittate. Peduncles many- 
flowered, shorter than the leaves ; flowers secund, nodding ; legumes 
reticulatcly veined, six — seven-seeded. Style jointed. Seeds round- 
ish, smooth. 
Description, &c. — This species has pretty little flowers, which are of a reddish purple when they first 
expand, but which turn blue as they fade. The leaves have generally three pair of leaflets, which are oval, and 
drawn out to a long point. The species is a native of Switzerland and Germany, generally in groves. It was 
introduced in 1629. It is hardy, but it seldom ripens seeds in this country, as its flowers are produced in April, 
when they are frequently injured by spring frosts. 
6.— OROBUS AURANTIUS, Stev. ORANGE-COLOURED BITTER VETCH. 
peduncles elongated, shorter than the leaves ; calyx pilose, with unequal 
teeth, four very short and one very long; legumes pedicellate. 
(G. Don.) 
Engravings. — Swt. Brit. Flow. Gard., 2d ser. t. 198 j and our 
fig. 7 in Plate 36. 
Specific Character. — Plant pilose ; stems simple ; angular; leaves 
with 5 — 6 pairs of lanceolate, bluntish leaflets, with diverging nerves ; 
Description, &c. — A tall slender plant, with five or six pair of broad smooth leaflets, which are the same 
colour on both sides, and are attenuated at both ends. The flowers are yellow, tinged with orange. The species 
is a native of the western regions of Caucasus, whence it was introduced in 1818 It is quite hardy, and flowers
