reg. 1, rrr. This pi. came up first as a weed in a box of Hoy a 
carnosa in my garden on the Caminho do Valle near Funchal 
in 1830, without any trace of its origin, soon becommg natu- 
ralized in the walks and borders. It has been lately observed 
in a neighbouring garden under similar circumstances by S r J. 
M. Moniz. May. — Habit much like that of G. Ivteo-album L. but 
with the lower branches more produced at the expense of the 
main st. stouter longer and more procumbent, and at once dis- 
tinguished by its thinly cottony or cobwebby light-yellowish- 
gr. foliage. Luxuriant spec, are sometimes (as also in G. luteo- 
album ) branched all the way up the main st. and 2 ft. high : 
but usually the main st. is from 4 to 12 in. high, and the side- 
shoots from its base 6-12 long. L. larger than in G. hiteo-alhum , 
more broadly spatlmlate and attenuated into long distinct pe- 
tioles, not amplexicaul, 1-24 in. long, 3 or 4 to 6 or 8 lines 
broad ; their upperside nearly naked, the underside like the 
st., and heads more cottony. Heads in fl. shaped like a flask or 
bottle with a globose gr. woolly base and naked shining pale 
yellowish brown or fulvous narrow neck ; hut in fir. or in dried 
ex. they become simply cylindrico-campanulate. They are not 
corymbose but densely aggregate in leafy cottony terminal short 
thick obtuse spikes or axillary tufts. Florets much fewer 
than in G. hdeo- album , and paler, the outer of the palest pos- 
sible straw-colour and only the 2 or 3 inner perfect fl. really 
v., all turning presently pale drab with a very slight tinge of 
red. Scales of inv. not silvery, their tips only naked and 
shining y.-brow-n. Recept. after the fr. has fallen concave or 
cup-shaped with the involucral scales reflexed. Pappus copi- 
ous pure-w. very deciduous fine and minutely rough. Ach. ex- 
cessively minute, \ a millim. long, broader and paler than in G. 
luteo- album, shortly and thickly oblong with slightly convex 
sides, subobtuse at each end, like little rice-grains or ants’ eggs, 
shining naked subpellucid very pale dull greenish straw-colour, 
subangular, minutely scabrous with raised points. 
G. spathulatum Burin, (a.d. 1788-9) being a Helichrymm 
{11. crispum (L.) DC.), Lamarck’s name for the present pi. 
(1786) takes precedence of Thunberg’s Gn. spathulatum (1794 
or 1818) =Leontcnyx spathulatus Less., DO., and all others.
