200 NOTES ON SOME PLANTS OF OTAGO, NEW ZEALAND. 
have two sets of specimens ; the one smaller in flower, the other taller 
in fruit. The latter is also more slender; the branching at the top 
more open; the sepals sometimes shorter than the capsule. This 
larger form differs little from L. usitatissimum, L., as it occurs in my 
British Herbarium from Charleston, Fifeshire. Both forms are erect, 
shrubby, and woody, with simple branches. Leaves vary much in 
length; in one form they do not exceed 4 inch, while in the other they 
are 2-1 inch long ; in the former case being broader, in the latter nar- 
rower; form varies from lanceolate to oblong- linca, or linear-lanceo- 
late; apex subacute to subobtuse; colour in drying in one form be- 
comes brown or blackish-brown, while in the other it retains its pale 
. greenness ; one nerve only is at all distinct ; margin revolute in both 
forms. Branches and flower-peduncles sometimes much grooved. 
Sepals show 3 (sometimes 5) nerves distinctly in the fruited forms ; 
the medium one very prominent, more so than that (midrib) of the 
leaves; it is less distinet, but still easily distinguishable under the 
lens, in flowering specimens. Sepals about equal in length to the 
capsule in the flowering, smaller form. Flower 2 inch long, white, 
handsome. 
I see no necessity for the two named varieties recorded in the Hand- 
book: their distinguishing characters are of insufficient value. 
The plant is cultivated in British nurseries, and is known to nur- 
serymen as a “fine perennial species, with dwarf branching habit, 
covered with large snow-white flowers of the size of the scarlet annual, 
L. grandifforum."* Tt is cultivated about Edinburgh, but is regarded 
as “ very precarious in this climate.” (Lowe.)

In my Otago plant the branches are woody ; the flowering twigs 
very sparingly leafy. Leaf-petiole 33 inch long. Leaf coriaceous, 
glabrous, suborbicular, 3-1 inch in diameter, distinctly mucronate or 
acuminate; dries to a leathery or blackish-brown.
