Nat. Ord, Crucirer2.—Tribe ALYSSINEA, 
Genus Drasa, Linn. (Benth. and Hook, f., Gen. Plant, vol. i., p. 74.) 
Drapa (Aizopsis) Mawii, parvula, dense cespitosa, caulibus brevissimis com- 
pactis, foliis densissime rosulatis breviter lineari-oblongis obtusis setoso- 
ciliatis nervo subtus valido, scapis per-brevibus aphyllis paucifioris, floribus 
amplis brevissime pedicellatis, sepalis oblongis concavis dorso setosis, 
petalis cuneato-obovatis albis, siliquis corymbosis breviter ellipsoideis com- 
planatis hispidis ad 8-spermis stylo brevissimo. 
It is not without hesitation that I propose as new a Euro- 
pean species of the large and very variable genus Drada, but 
after a very careful examination and comparison I am unable 
to match the plant here figured with any known to me by 
specimen or description. It belongs to the section Azzopsis, 
and its nearest affinity is with the Spanish D. cantabrica, 
Willkomm (? D. Dedeana, Boiss. and Reut.), which differ in the 
yellow petals and elongate fruiting raceme. It also resembles 
very closely, in habit especially, the Draba hispanica, Boiss., 
a native of Spain and Algeria, but differs conspicuously in 
the white flowers, broad petals, flat pod, and very short style. 
It has also the habit, form of pod and style, and many of the 
characters of the D. Zahibruckneri, Host, of the Eastern 
Alps; but that has small flowers and glabrous pods. 
Draba Mawii is a native of Pancorbo in Old Castile, 
between Burgos and Miranda, where it was discovered 
by Mr. Maw in 1870, and introduced into his garden at 
Brosely and into the Royal Gardens of Kew. It 
flowered in the spring of 1873, and the fruit ripened 
for the first time in May, 1874, It is an excellent rock 
plant, of compact habits, bright green foliage, and red-brown 
buds, that are succeeded by crowded pearly flowers. 
Descr. Forming low densely tufted bright green patches. 
’ Stems much branched, densely clothed with spreading rosulate 
leaves. Leaves $ to 4 of an inch long, linear-oblong, obtuse, 
shining, margin pectinate, with rigid incurved or spreading
