Stamens 2 inserted within the mouth of the corolla. Anthers large on top, 
and cleft half way up, capsule narrow-oblong, seated in a cup-shaped disc.

The tetramerous flowers and clustered arrangement of the spikelets 
place this species also in Mitrasacme, and the very small triangular-shaped 
leaves distinguish it from M. hookeri. The peculiar leafiess-like branches 
and inconspicuous flowers of this small alpine cause it to be easily overlooked, 
but it is none the less interesting to botanists. Named in honour of T. F. 
Cheeseman, F.L.S., who has added much to our knowledge of the botany of 
New Zealand. 
Mitrasacme petriei, Buch., n.s 
Stems prostrate, branched, branches ascending, pres long. Leaves 
4+} inch long, oblong, or linear-oblong, obtuse, membraneous, sparingly 
cilio-glandular on the margins, 1-nerved, in opposite pairs, and connate at 
the base without stipules; flowering branches covered on the upper $ of 
their length with closely-arranged tetramerous cilio-glandular leaf-like 
bracts. Flowers numerous, solitary in the axils of the upper bracts. Calyx 
deeply 4-5-cleft, lobes faleate, varying in size, linear-obtuse, and cilio- 
glandular on the margins. Corolla with a rather long funnel-shaped tube ; 
lobes 4, unequal, linear-oblong, acuminate, spreading. Stamens 2, filaments 
short, inserted within the mouth of the corolla, anthers short, cleft half way 
up and rounded on the points. Capsule ovoid, compressed, seated in & 
Shallow cup. Seeds ovate, few.

The ‘abenihicbs flowers and absence of leaf stipules in the present plant 
are sufficient reasons for placing it in Mitrasacme, and the large distant 
leaves present sufficient claim as a new species. This addition to the 
Loganial alliance in New Zealand also maintains the peculiar feature of 
Possessing only two stamens.
