he first variety of H. humifusum to be ps apie rd aaare 
o be B magnum of Batard’s Flore de Maine et Loire, Suppl. p 
(i813) plant, found near Cholet, differentiated solely as ae 
four times as large in all its parts as ordinary H. humifusum, with 
nearly cylindrical stem 
n 1824 Villars’s H. Liottardii was reduced to a variety of 
if; asics feist in or Candolle’s Prodromus, i. p. 549, where it is 
diagnosed, ‘“‘Caule magis minuto erectiore bisannuo, Aoribti 
aliquando 4- ipeirtitin calyce longiore.’ 
_A fourth plant was added to this group in Peterman’s Flora 
Lipsie, p. 565 (1 838) as H. decumbens, which is described thus: 
“Caulis filiformis, procumbens; folia Se aes phylla lan- 
ceolata, acuta, glanduloso- -serrulata. Habitus exacte H. humifust 
et plerumque major; phylla angustiora, antkas enantifent serrulata, 
serraturis apice glandulosis.” 
H. decumbens, as well as H. Liottardii, was reduced to a 
variety of H. hwmifuswm in Reichenbach’s Icones, vi. p. 68 (1844), 
where both forms are figured with the specific type; and a further 
yeuee) of this —_ — peas in Willkomm & i 
“In Britain. i. Jeinafit um had been meanwhile described and 
figured in English Botany, 1226 (1803), where the plant is drawn 
with the glandular-serrate sepals of H. decumbens; and H. linarti- 
folium was added to the British Flora by Babington i in Eng. Bot 
Suppl. 2851 (1840), his account of the plant being taken from 
specimens eaamg by himself in Jersey, and by Borrer at Cape 
Cornwall during the previous year. The figure was drawn from 
a Cornish example. 
H. humifusum and H. linariifolium have been retained as 
a Hg in Ver a British Floras, and while Hooker 
(Stud Flora, ed. 3, p. 73 (1884)) places them in separate 
generic Sa ta based on the entire or dentate margins of the 
— in accordance with the arrangement of De Candolle (Prodr. 
p. 548), Syme and Babington both recognize that gland-tipped 
iis soa occur in uma arr as in the other. 
The connection of H. h umifusum with H. linariifolium by a 
= of ieteriniedink ate porsios was suggested in 1892 by Dr. Gillot 
e Botanique, x. p.653, where he writes: ‘‘ 11 me semble
