describes it as introduced from Madeira in 1777; and so 
matters rested till 1810, when the new edition of ‘* Hortus 
Kewensis”’ appeared, wherein are described the above- 
mentioned EH. candicans, Jacq., H. fastwoswm, Ait., from the 
Canaries (Masson), with a cylindric raceme and acute sepals, 
and H. nervoswm, Ait., from Madeira (Masson, 1877), with 
ovate raceme and subobtuse sepals. 
In 1811 the younger Jacquin in his “ Ecloge”’ figured, 
also under the name of H. fastwoswm, a plant which he says 
appeared amongst the pots of H. candicans in the Schoen- 
brunn Gardens, and differs from it; but he does not say 
how. It is evidently not Aiton’s ZL. fastwosum, having a 
large broad panicle of pale blue flowers. 
De Candolle in 1813, in the Catalogue of the Montpellier 
Garden, has candicans as a Madeiran plant of Aiton’s in 
the list (p. 25), but attributes it to Linn. fil. in his “* Adno- 
tationes”” (p. 108), and describes it as having a spiciform 
panicle and intense blue-purple flowers. He also describes 
fi. virescens, DC., from Teneriffe, to which he refers L. 
candicans of the elder Jacquin, but not of Linn. fil.; it too 
has a spiciform panicle and bright blue corollas with white 
lines at the base. of 
In 1815 an H.. candicans is figured by Edwardes in the a 
Botanical Register (vol. i. t. 44) with a compact cylindric - 
spiciform panicle, and small bilabiate corollas with rounded 
lobes, the two upper small and blue, the’ three lower white. 
Lehman, in his “Plant. Asperif.” (1818), describes candi- 
cans, Linn. fil., Jacquin and Aiton, as a Madeiran plant 
with a conical panicle, oblong acute sepals and blue corolla; 
and fastuosum, Jacq. fil. (candicans, DC.), native country 
unknown, as differing from candicans, Linn. fil., in its 
broader more hirsute ciliate less white leaves, large ovate 
_thyrse, dense spikelets and lanceolate sepals. 
Webb in “Hist. Nat. Ins. Canaries” (1845?) retains 
virescens, DC., referring to it HE. candicans, Jacq., and 
doubtfully, H. fastuosum, Jacq. fil.; he says it differs from 
candicans, Linn. fil., in the short subvelvety pubescence, and 
that: it is found on the Mountains of Orotava only. 
De Candolle in the Prodromus (1846) describes candicans, 
Linn. fil. and Jacq. Pl. Rar., with virescens, DC., as a 
synonym, as with a lax panicle and corollas white or blue 
with white lines; and fustwosum, Jacq. fil. Eclog. (with
