and MiscellMieous Particulars. 
1385. Notoceras. From hwta?, the back, and th^o.?, a horn. The structure of the pod of this genus is inter- 
mediate between Erysimum and Capsella. The species are small annuals, with very minute flowers, which are 
sometimes apetalous. 
1386. Barbarea. A name used by Dodoens, because the plant had been called the herb of St. Barbara by 
some preceding botanists. B. vulgaris is sometimes cultivated as a spring salad, but is much less delicate than 
the common cress, and has nothing in flavor to recommend it. B. prascox, the American or BelleLsie cress of 
gardeners, is preferred to the other, and cultivated in a number of gardens. 
1387. Braya. A curious little plant, with the habit of Arabis cjerulea. Leaves are linear, racemes terminal, 
flowers purple. The genus is not completely known ; but it appears to be intermediate between Siliquosee and 
Siliculosae ; related to Draba on one hand, and Arabis on the other. It is a native of the Carinthian alps, 
where it was found by Dr. Hoppe, who named it after Count Bray, a German nobleman. 
1388. Parrya. Named by Mr. R. Brown, after Captain Edward Parry, the commander of the British expe- 
ditions to discover the north-west passage round America. It was found upon Melville island, and once was 
raised from seeds brought home by some of the officers, but it never flowered^ and is now lost. 
1389. Turritin. From iurris, a tower ; the leaves and seeds giving the stem a pyi-amidal form. This genus 
is principally distinguished from Arabis by its seeds being in two rows, and by its habit. 
1390. Arabis. Native of Arabia, according to DeTheis ; but this is a forced explanation, and scarcely the 
true root of the word. Distinguished from all the neighbouring genera by its linear compressed siliques, and 
flat valves.
