Plantago asiatica-erosa-major, or cf. asiatica, with frequently (but not
always) incised leaves (like incisa), elongated, uneven pyxidia (like
asiatica), gaps (like erosa), seeds numerous 6-9-12 (like major) but
typically elongated (like asiatica), without ridges (like asiatica) or
with weak surface ridges, typically plant of altitudes > 500 m, South
China (PE, TNS), Myanmar (MBK), North Thailand (MBK), Taiwan (TNS, TUS)
and maybe also Indochina.

This form might be similar to P. cavalieri H. Levelle described from
Yunnan (sequenced from PE but seeds not counted).
