“ THE FLORA OF CHINA. HINA possesses what is probably one of the largest flora in the world. "The most moderate estimate cannot put the whole flora as containing less than twelve thousand species," says Sir W. T. Thiselton Dyer in the "Index Floræ Sinensis," which enumerates 8,271 species, 4,230 of which are endemic, or not known to occur outside the Chinese Empire. The popular cry that China requires nothing from abroad, having all that she needs within her own boundaries, is no empty boast so far as her vegetation is concerned. ”
