Nota4. Die L. picta ist besonders charakterisiert durch den ganz eigentümlichen 
Bau der sehr schmalen Perigonblütter. Sie besitzen ein schmales, kastanienbraunes, an 
beiden Seiten scharf begrenztes, nach oben verjüngt bis in die Spitze verlaufendes Mittel- 
feld, während die Seitenflächen weißgefärbt und dünnhäutig sind. 
Die nicht sehr glückliche Bemerkung von Ricuanp, dass die L. picta der L. nemorosa 
und nivea einigermaßen ähnlich sähe, hat die richtige Deutung der L. picta sehr er- 
Schwert. 
Nota 2. Zu L. picta var. Banksiana dürfte wohl auch die mir unbekannte L. sub- 
clavata Colenso gehören, deren Diagnose ich nachstehend mitteile: 
W. CoLexso, A Description of some newly discovered and rare indigenous plants, 
in: Transactions and proceedings of the New Zealand Institute, 1886, XVIII, p, 256—278; 
p. 276: L. sub-clavata n. sp. 
A tufted erect herb, branching from the roots. Culms slender, sparingly leafy, 
18—24" high. Leaves numerous, flat and grass-like, 5—6” wide, 46 nerved, with dis- 
tant transverse nettings, apices thickened terete and sub-clavate, margins slightly and 
distantly serrulate, and sparsely ciliate with very long whitish hairs. Flowers in a long, 
loose, slender panicle of 2 (sometimes 3) sub-sessile broadly ovoide many - flowered 
heads, several inches apart; heads Lait diameter, simple or compound, on short pedicles, 
the lowermost head having 2—3 long foliaceous bracts at base, their apices thickened 
and terete like those of the leaves, the uppermost head is usually bractless. Perianth 
small, 4”’ long; segments ovate-acuminate, whitish brown with a dark central line, 
much longer than capsule; stigmas long, flexuous and rough. Capsule sub-ovoid trique- 
trous, smooth, shining; valves broadly oblong-lanceolate, apiculate, with a strong central 
vein. Seeds oblong, turgid, darkish brown, shining, finely reticulate - striate, with a 
dark spot at tip, the hilum produced and puberulous, and a narrow white line forming 
the ventral suture. Bracleoles small, broadly ovate, white, shining, adpressed; tips 
minutely ragged with a mucro.
