DRABA. 
by oval-pointed, veinous bald pods. The plant varies considerably 
in size and stature, and some of its more marked forms are 
occasionally offered as species. These are DD. Bertoloni, affinis, 
elongata, bosniaca, montana, Beckeri, alpina, and scardica. With no 
doubt as many more as you could choose to differentiate, each range 
that possesses the species probably possessing some special local form 
of it, and that again varying into different developments of which you 
well might name the extremer versions. None will be found much 
finer, however, than some that may be collected no further away 
than the Alps of Switzerland. One of the most marked named off- 
shoots, however, is also a Swiss plant—this is the minute stunted 
species almost universal at great elevations in the granitic Alps, and 
sometimes sent out as WD. Zahlbriickneri, bemg in reality D. 
Hoppeana, q.v. 
D. aeizion (D. lasiocarpa, Koch.) is also a plant of the limestones, 
but only from the Carpathians through Transylvania, to Dalmatia, with 
one outlying station in South Austria. It is much larger in the clump 
than D. aeizocides, and of these larger rosettes there are fewer, only 
two or three, while from them rises a taller stem, carrying a larger 
head of smaller, paler flowers, and elongating into quite an impressive 
spike of flat downy pods. Its varieties are D. a. compacta, and D. 
a. Haynaldii, this last appearing often as a species, and being a small 
compact and very narrow-leaved development of the type, with 
stems of only an inch or so, and only a few flowers to the head. 
D. armata is a sub-species of D. longirostra, q.v., almost neater and 
smaller and yet more charming in its reduced, concise, minute habit, and 
the fine golden blooms that seem even finer for the dainty scale of 
the massed rosettlings above which they stand. This plant con- 
tinues the distribution of rare D. longirostra on into Croatia, where it 
is yet rarer. 
D. Athoa occurs only on a few mountain tops of Greece, and is a 
handsome species making a dense and rather wide mass of specially 
spine-edged, broadish foliage, with the foot-stalks of the flowers 
longer and more spreading at the top of the bare little stout 3-inch 
stems, so that the bright yellow crosses, with their tall anthers, look 
specially wide in the cluster. A form of this is D. A. Lacaita, a smaller, 
compacter, tighter tuffet still, with short anthers and short petals. 
Possibly this may be a true species. 
D. aurea is the type of D. cuspidata, q.v. 
D. Bertoloni. See under D. aeizoeides. 
D. bruniaefolia. See under D. olympica. 
D. bryoeides. See under D. rigida.
