THE FLORA HONGKONGENSIS. 107 
distinguished (Ann. Se. Nat. Par. ser. 5, v. 219):—* a. collina; 
branching; stem downy; leaves small, rigid, roughly hairy and 
downy; flowering branches several; ligules scarcely longer than 
than the disk. Asteromaea indica, Blume; DC. Prod. v. 308. 
On hill-sides, grassy hillocks, graves, &e. B. rivularis ; simpler ; 
stem smoothish ; leaves larger, flaccid, downy or nearly smooth ; 
flowering branches few ; ligules frequently one and a half times as 
long as the diameter of the disk ; scales of the pappus less deve- 
loped than in the last variety. Hisutsua cantoniensis, DC., Pred. 
vi. 44. On the banks of rivers and streams, along canals, in 
ditches, invariably growing in mud.” I have always found the 
pappus-scales laciniate in this plant. 
*Aster striatus, Champ. 
According to Miquel (Ann. Mus. Bot. Ludg.-Bat. iii. 197), 
the Japanese Calimeris ciliata, A. Gr., mentioned by Bentham 
as a spurious Calimeris is identical with this. If so, it is cer- 
tainly no Calimeris as that group (which I concur with Mr. 
Bentham in regarding as identical with Boltonia +) was defined 
by Cassini, and by Torrey and Gray in the * Flora of North 
America,’ but a true Aster, belonging to the section named Aste- 
romeris by Turezaninow, and Orthomeris by Torrey and Gray. 
The allied genus, Heteropappus, Less., intermediate between Bol- 
tonia and Aster, reduced to Calimeris by Asa Gray, but which is 
quite as well characterized as the majority of Astereous genera, 
is represented on the adjacent mainland by H. Sampsoni, Hance, 
which may possibly occur in Hongkong. 
*Aster trinervius, Rozb. 
In the living plant the pappus is either pure white or dull 
grey; but in the herbarium it turns of a salmon-colour, like that 
of Pyrrhopappus or Gerbera. 
*Conyza japonica, Less.; DC. Prod. v.382. (=C. veronicifolia, Wall. ; 
Benth, Fl. Hongk. 176.) 
*Blumea. 
I am distinctly of opinion that there are more than six species 
of this genus in Hongkong; and, as I have before observed 
(Seem. Journ. Bot. vi. 174), many forms seem to hold to their 
characters of aspect, stature, shape of leaves, and odour (which 
t C. integrifolia, Turez., implicitly excluded by Mr. Bentham, indubitably 
belongs here,
