Of the three remaining species E. borealis has only two authentic 
records to its credit, viz. Penhallow Moor, Newlyn East (C. C. Yigurs, 
1910), and Port Holland in district 6 (E. Thurston, 1913); E. curia , 
recorded from eight localities, chiefly in West Cornwall, appears to be, 
as far as this county is concerned, an obscure form allied to E. nemo- 
rosa, but confined to heathy places ; and E. brevipila is a plant of 
well-defined characters, but of rather wide range of habitat, being 
found in thin grass, healthy places, waste ground, or cliff slopes. The 
last-named occurs in each of the eight districts, but its main distri¬ 
bution, judging from its recorded station, is distinctly north and west. 
DIPLOLOPHIUM AND PHYSOTKICHIA. 
Br C. Norman. 
In looking through the species of Eiplolophium and Ehysotrichia 
in the British Museum, it became evident to me that some confusion had 
arisen between the two genera, and that species really belonging to the 
former have been assigned to the latter. Both genera belong to the 
Tribe Seselinese (Umbel 1 iferse) and are confined to Tropical Africa. 
Eiplolophium was founded by Turczaninow in 1847 (Bull. Soc. 
Imp. Nat. Moscou, xx. 173) on a plant from Abyssinia ( Gachrys abys- 
sinica Hochst. Schimper, No. 213), which he called Eiplolophium afri- 
canum ; Turczaninow also cites Kotschy , ZVb. 572 , from “ ^Ethiopia.” 
The herbaria of the British Museum and Kew have each a sheet of 
Kotschy’s plant : this is now known as E. abyssinicum Bentli. & 
Hook. f.: it is a large stout plant, with large many-rayed umbels 
with conspicuous bracts to involucre and involucel, and hairy fruits 
without calyx-teeth. 
Ehysotrichia was founded by Hiern in 1873 (Journ. Bot. xi. 161) 
on a plant collected in Angola (Welwitsch, 2512), which he named 
E. Welwitsch ii. This is a slender , graceful plant, with small, few- 
rayed, umbels with relatively inconspicuous bracts to involucre and 
involucel, and papillose fruits with persistent calyx-teeth. It seems 
to be rare ; the only specimens at Kew or in the British Museum are 
those collected by Welwitsch. 
The following species hitherto placed in Ehysotrichia have the 
characters of Eiplolophium , and should be transferred to that genus: 
E. Euchanani Benth. ; E. Swynncrtonii Bak. fil. ; E. arenaria 
E. Ilelence Buscalioni & Muschler. 
Engler & Gilg 
Diplolophium Turcz.

+ 3-4 cm. long . 1. E. abyssinicum. 
Segments of leaves acicular, stiff; seg¬ 
ments + 1 cm. long . 2. E. zambesiacum. 
Stem-leaves bipinnate. 
Leaflets + 20-40 mm. broad . 3. E. Euchanani.
