150 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 
in the less stout habit, the thinner leaves, and the much scantier indumentum of the calyx. 
The difference between Leptospermum javanicum and L. recurvum is not greater than that 
between typical Z. flavescens, Sm., and some forms referred to var. obovatum of this species. 
The amount of hairinessin L. recurrum is exceedingly variable, and plants growing close 
to each other may possess either leaves with a dense white silky coat on the back or 
leaves almost without hairs. The same may be said with regard to the calyx. Thus 
the difference is reduced to the stunted habit and the minute leaves. Such minute 
leaves, however, may be found occasionally also in L. javanicum, at the base of the branches 
or on short and poorly developed lateral shoots. This form of leaves evidently has become 
general in L. recurvum, whilst the texture grew firmer at the same time and the margins 
recurved, as often occurs in similar cases with alpine or very exposed forms.

Maripari Spur, alt. 5500 feet ( Haviland, 1261). 
A very distinct species, characterized by the small oblong leaves and the solitary ovules. 
Young leaves are sometimes very like the minute leaves which now and then occur in 
Decaspermum paniculatum amongst the normal ones, or like those of D. Blancoi, Vidal, 
to which the species is nearest allied; but they soon become much firmer, whilst the 
margins curl in, and then they resemble very much those of Vaccinium Vitis-Idea. 
I found the ovules always solitary, rising from a little above the base of the cell. Never- 
theless, the back of the cell may sometimes be seen intruding slightly into the cell, 
forming a faint central ridge, thus indicating the formation of a false septum, which is 
more or less normal in other species of Decaspermum.
