in the field it often grows in the same localities as 4. ob/iguum and 
there can always be distinguished at a glance. When it grows in 
the open sun it often becomes contracted and compact in habit, 
but the typical form of the species is so unlike LB. ob/iquum that it 
is more rational to consider it a distinct species. (Cf observations 
under 4. ¢ernatum.)

(Type from Auckland, New Zealand, Hay; in herb. k. k. Hof-

embracing B. ¢ternatum, but this reference signifies nothing in this 
day of more rational conceptions of geographic distribution ; with. 
out having seen the type it seems best to leave the species in doubt 
though it may be one of the forms of the Australasian B. australe.
