THE FLOHA HONGKOlfGBNSIS. 19 



distiaguished (Ann. Sc. Nat. Par. ser. 5, v. 219):— "a. collma; 

 branching ; stem downy ; leaves small, rigid, roughly hairy and 

 downy ; flowering branches several ; lignles scarcely longer than 

 than the disk. Asteromaea indica, Blume; DO. Prod. v. 303. 

 On hill-sides, grassy hillocks, graves, &c. )3. ri/eularis ; simpler ; 

 stem smoothish; leaves larger, flaccid, downy or nearly smooth ; 

 flowering branches few ; lignles 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, Prod, 

 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 (Aon. Mus. Bot, Ludg.-Bat, iii. 197), 

 the Japanese Calimeris eiliata, A. Oct., 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 f) was defined 

 by Cassini, and by Torrey and Gray in the ' Elora of North 

 America,' but a true Aster, belonging to the section named Aste- 

 romeris by Turozaninow, and Orthomeris by Torrey and Gray. 

 The allied genus, Meter o^appus, 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 S. Sampsoni, Hance, 

 which may possibly occur in Hongkong. 



*Aster trinervius, Roscb. 



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 FyrrJiopcyppus or Gerbera. 



♦Conyzajaponica, Less. ; DC. Prod. v. 382. (=C. veroiiicifolia. Wall. ; 

 Benth. Fl. Hongk. 176.) 



*Bliimea. 



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. integrifoUa, Turoz., implicitly excluded by Mr. Bentham, indubitably 

 belongs here.
