more scabrous leaves, the greater length of its stipules, and its exserted 

 style, seem to justify the separation of it from any variety of that spe- 

 cies. It was obtained from the Chiswick Garden by Mr James Mac- 

 nab in September 1838, and flowered very freely in the greenhouse of 

 the garden of the Caledonian Horticultural Society in July and Au- 

 gust. Mr J. Macnab does not know whonce it Avas introduced ; he has 

 made many attempts, always unsuccessful, to propagate it by cuttings 

 from the branches, but has found it very easily propagated by slips from 

 the roots, not half an inch long, covered so as to leave the upper ex- 

 tremities only exposed, and level with the surface. He has distributed 

 many plants obtained in this way under the name I have adopted. 

 There is scarcely any tiling more brilliant in cultivation than a large 

 specimen covered with clusters of its most splendid flowers. The seeds 

 formed, but did not ripen. 



Erysimum Perofskianum. 



JE. Perofskianum ; annuum vol bienne, setis bipartitis scabrum ; caule 

 simplice, foliis lanceolatis, remote denticulatis ; pedicellis calyce 

 duplo brevioribus ; petalorum ungue calycem vix superante ; siliquis 

 setis bipartitis scabris, stylo teretiusculo pedicelloque quintuple lon- 

 gioribus. 



Ei7simum Perofskianum, Fhch. ^- Meyer, Index quartus Sem. in Hort. 

 Bot. Imper. Petropolit. ann. 1837.— Bot. Mag. 3757. 

 Description. — Stem ascending, weak, angled, simple. Leaves of nearly 

 uniform green on both sides, scattered, lanceolate, remotely denticu- 

 late, attenuated at the base, recun-ed at the apex, with bipartite ad- 

 pressed hairs ; middle rib prominent behind, 2-4 lateral obscure nerves. 

 (Sj/^jfe racemose, terminal, many-flowered, pedicels spreading, Cali/x 

 pale, erect, deciduous ; sepals unequally bulging, and distant at the 

 base, keeled at the apex, especially the two which are longer and nar- 

 rower. Corolla of uniform orange colour; laminaj of the petals sub- 

 orbicular, spreading at right angles, at first slightly concave, afterwards 

 reflected, shorter than the slender wedge-shaped claws, which are 

 scarcely longer than the sepals. Stamens distinctly tetradynamous, the 

 shorter equal to the claw.s of the petals. Hypoi/j/nous ijlauds dark green, 

 indented by the claws of the petals, secreting much honey. Pistil 

 longer than the stamens ; germen spi-eading, 4-sided, slightly pubescent, 

 having many ovules in one row ; style less than half the length of the 

 germen ; stigma capitate, cleft across the vertex. Siliqua compresso- 

 four-sided, rough with bipartite adpressed hairs, crowned with the per- 

 sisting style, which is nearly as long as the pedicel, and 4-6 times 

 shorter than the siliqua. 

 . Seeds of this very pretty plant (which belongs to De Candolle's 2d sec- 

 tion of the species, Cuspidaria) were received at the Royal Botanic 

 Garden, Edinburgh, in May 1838 from Dr Fischer, and the plants 

 raised that season flowered in a cold frame in May 1839. They ripened 

 seed. The species is a native of Cabul.
