LXXIJ. LORANTHACE. 
An important series of memoirs on the structure and classi- 
fication of this order, by the French botanist Van Tieghem, is 
printed in the Bulletin of the Botanical Society of France for 
the years 1894-96 (Vols. xli. to xliii.). One of these memoirs, 
entitled ‘‘ Sur les Loranthoidées de la Nouvelle-Zélande,” deals 
specially with the New Zealand species included by all previous 
writers in the genus Loranthus, and contains many original 
and valuable observations. In addition to the 5 species given 
by Hooker in the Handbook, Van Tieghem accepts the 
whole of those (5) described by subsequent authors, and pub- 
lishes 5 others as new, thus enumerating 15 species in all. 
These he distributes in 7 new genera, with one exception con- 
fined to New Zealand. Van Tieghem’s liberal ideas as to the 
number of genera are not restricted to the New Zealand 
species, for in a conspectus of the whole order he admits no 
fewer than 133, whereas Hooker and Bentham, in the “‘ Genera 
Plantarum,’ only gave 13. Van Tieghem’s researches have 
to a large extent supplied the basis of a new classification of 
the order proposed by Engler in ‘Die Pflanzenfamilien”’ 
(Nachtrage, i. 124), although most of his genera are reduced to 
the position of subgenera or sections. The following sketch 
will show how the New Zealand species are disposed of under 
Engler’s arrangement. 
* Perianth double. 
Ovary more or less distinctly 2- or more-celled 1. ELYTRANTHE. 
Ovary distinctly 1-celled. Anthers basifixed 2. LORANTHUS.

or branches as ae es .. 5. KORTHALSELLA.

Mr. Mayo informs me that this is occasionally parasitic on introduced 
trees. At Motueka (Nelson) he has observed it growing on Pears, Piums, 
and on Robinia pseudacacia.

Colenso’s Loranthus punctatus (Peraxilla punctata, Van Tiegh. ; Ely- 
tranthe punctata, Engl.) is doubtless identical with this species, judging
