Inheritance of growth habit and calyx marking in subterranean clover (Trifolium subterraneum Linn.) : thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at the University of New Zealand, by "Bulk"
Subterranean clover is an annual legume which perpetuates itself in pasture by reseeding. After flowering the peduncle turns downward, and the head enters the soil. From this habit the common and specific names have been derived. The original home of the species is stated to be Southern Europe, Western Asia to India and North Africa (Cheeseman 1925). An account of the accidental introduction of the species into Australia gives the period as 1880-1890 (Gardner & Dunne, 1933). From there, probably, it spread to New Zealand. Though the actual time of its arrival cannot be stated, it was recorded by Cheeseman in 1906 near Auckland, where for many years it has been known as "Mangere" clover. [From Introduction]
