Pimpinella pseudo-caffra, sp. nov. 
Herba annua gracilis, circa metralis; caule simplice, erecto, glabro, 
tereto ; foliis lieteromorphis ; radicalibus simplicibus, triangularibus, 
obtusis, membranaceis, utrinque glabris late cordatis, marginibus 
insequaliter serratis ; petiolis, longis, ad basim brevissime vaginan- 
tibus, pilis longiusculis sparse vestitis, suffultis; caulinis inferioribus 
insequaliter bisectis, marginibus exterioribus denticulatis, dentibus 
nferioribus bifidis ; caulinis superioribus bipinnatis ; ad segmenta sub- 
ulata insequalia distantia, reductis. Umbellis glaberriinis, paucira- 
diatis, tenuibus; pedicellis tenuibus; involucro et involucello 0. Calycis

albidis. 
Congo: Kundelungu, “in damp places”; Kassner, 27831 in 
Herb. Mus. Brit. 
A slender graceful plant in flower; quite glabrous except for the 
petiole of the lower leaves : principal measurement approximately, 
radical leaves 4*5-6 X 5-6*5 cm., petiole 10-12 cm ; lower cauline 
leaves lobes 5x1*5 cm. and 3x1 cm., petiole 7 cm.; upper cauline 
leaves 2*4-4*5 cm. long; rays of umbel 1*5-2 cm.; pedicels 4-5 mm. 
Th is, like the preceding, belongs to the subgenus Eu-pimpinella, 
section Tragoselinum. It is nearly allied to P. caffra Harv., which 
it much resembles in general appearance, but is well separated by 
being quite glabrous, whereas P. caffra is completely clothed with a 
rather harsh indumentum; in P. caffra the radical leaves are of 
a thicker texture and considerably smaller size. 
A NEW CERCOSPORA ON HUMULUS. 
By E. S. Salmon and H. Wormald. 
In September 1922 we observed a fungus attacking the leaves of 
the cultivated Hop ( Humulus Lupulus L.), in a hop-garden near 
Canterbury, Kent. On examination it proved to be a species of 
Cercospora not hitherto described. We were aware, however, through 
correspondence in 1919 with Prof. S. Hori, of the Imperial Agricul¬ 
tural Experimental Station, Nishigahara, Tokyo, Japan, that a species 
existed on Humulus spp. in Japan, and had been called “ Cerco¬ 
spora Humuli Hori.” Prof. S. Hori has now sent us examples 
of his species, with the information that “ the Japanese Cercospora 
on Humulus spp. was described as a new species in my monograph 
of Japanese Cercospora in our language.” The English and the 
Japanese specimens were found on comparison to belong to two 
quite distinct species. At the request of Prof. Hori we give below 
the diagnosis (in English) which he communicated in his letter. 
We have added a diagnosis in Latin, which for those who do not 
recognise descriptions in Japanese will be its first publication. 
The following is the description of our species, which we propose 
to cull Cercospora cantuariensis :—
