always nearly if not quite half as broad as long, i. e. not quite 
half an in. (10-11 millim.) long, ^ in. (4 or 5 millim.) wide, 
tumid and corky towards the edges, scarcely or but very nar- 
rowly winged, imperfectly bursting and discovering in the mid- 
dle the single pendulous large oblong seed, not separating. — 
Varies not only greatly in size, height and foliage, but in being 
(1) more hairy and less glaucous, (2) nearly or quite smooth 
and very glaucous, (3) pouches truncate or rounded at top, 
and sometimes a little narrowed or attenuated, though scarcely 
cuneate or wedge-shaped, at the base : but all these forms are 
too much blended together to be separable. And although the 
pouches vary thus in shape a little from their normally oblong 
character, the proportion of their greatest width to their length 
is quite constant, even in the most cuneate forms, in which the 
upper trail verse diameter manifestly exceeds the lower or basal. 
— United by Koch to I. tinctoria L., but more nearly perhaps 
related to I. alpina All. ; the pouches being of precisely the same 
shape, only considerably smaller. Still in I. alpina All. the 
pouches are not only 15-16 millim. long and 8 wide, but they are 
also altogether thicker, though neither tumid or corky towards 
the sides, nor more distinctly winged than in I. prcecox Kit. — 
I. prcecox RFG. ii. t. 4. f. 4178 does not seem to differ mate- 
rially from f. 4177, which is the true I. tinctoria L. But the 
fig. 4177 b, u I. bannatica Link,” exactly represents the fruit of 
the Madeiran plant. By Steudel both I. bannatica Link and 
I. bannatica Kit. are referred to I. tinctoria L., in which the 
pouches are not only finely attenuated downwards into the stalk, 
but are uniformly at least three times as long as broad. 
Occasionally used for dyeing blue by the country people, but 
now almost superseded. Formerly it was much cultivated for 
commerce, but it is now quite neglected : and though extensively 
and perfectly naturalized in Madeira, its non-occurrence in Porto 
Santo and especially in the Dezertas is a fact (considering its 
favourite places of growth) opposed to its being truly indi- 
genous.
