30 ART. I.—B. HAYATA : 
In my papcr above cited, I mention that the present plant 
azrecs quite well with the description of Arabis taraxacifolia 
Anvers. given in Hook. f. Fl. Brit. Ind. I. p. 136, and also very 
like the European A. arenosa Scor. Although I did not, at that 
time, see ANDERSON’s specimen, I thought that the plant might 
be identical with A. taraxacifolia. While studying here at Kew, 
I have compared it with the type of the some species and 
bave found that they are quite different. The Formosan plant 
is distinguishable from the Indian in having nearly erect and 
stouter pods, larger seeds, and smaller leaves and also in 
bearing very long stolons. The Indian plant appears to be of 
more tender habit, with curved pods, narrower, smaller seeds, and 
larger, thinner leaves. Moreover, the present plant differs from 
A. arenosa Scop. in having longer pods, smaller flowers, and 
leaves with more rounded lobes. The description given above is 
drawn up from a specimen numbered 680, which is of a rather 
elongate form and prostrate habit.
