92. Parietaria debilis Foist, f., M. 112. (= Urtica debilis Endl., E. 81.) 



H. C! Quintall ! (Specimen sent to Mr. W. R. B. Oliver.) 

 Kermadecs, Lord Howe, New Zealand, Australia, and widely elsewhere. 

 Malaisia tortuosa Blanco, M. 107, is excluded on the same grounds as 



for Peperomia leplostachya. It has probably been introduced in confusion 



with the Lord Howe plant. 



LORANTHACEAE. 



93. Korthalsella articulatum (Burn, f.) Van Tiegh. (= Viscum distichum 



Endl., E. 118 ; V. articulatum Burn, f., M. 99.) 



Abundant not only on Baloghia and other natives, but on many intro- 

 duced fruit-trees. It kills lemons, oranges, and peaches, and is quite a pest 

 on the island. 



Lord Howe, Australia, India, Polynesia. 



Santalaceae. 



94. Exocarpus phyllanthoides Endl., E. 91, M. 100. 



Common in the forest. 



One of the most durable woods on the island, but the larger trees have 

 now all been cut down. 

 Endemic. 



Olacaceae. 



95. Pennantia Endlicheri Reiss. (= P. corymbosa Forst., E. 140, M. 25.) 



Top of Mount Pitt ; not common. 



Endemic. 



There has long been known from Norfolk Island a species of Pennantia 

 which has usually been considered to be identical with the New Zealand 

 Pennantia corymbosa. It appears first of all in Endlicher, p. 80, No. 140 

 (1833), and there Endlicher identifies it with Forster's P. corymbosa from 

 New Zealand. In 1842 Reissek made a separate species of it, under the 

 name P. Endlicheri ,f and is followed by the " Index Kewensis." Maiden, 

 however, regards it as synonymous with P. corymbosa, and states (M. 25), 

 " I am of opinion that the Norfolk Island species is identical with the New 

 Zealand one." This opinion seems to me scarcely justifiable, and for 

 reasons about to be given I think that the specific name " Endlicheri ' 

 must be revived for the Norfolk Island plant, and the species must be 

 regarded as distinct. 



On examining the Norfolk Island form it is apparent at a glance that 

 the leaves are larger and more membranous than in the New Zealand species. 

 Indeed, similar differences exist between the two as between P. excels urn 

 and P. excelsum var. psittacorum of the Kermadecs and Norfolk Island. 

 Such differences as these are perhaps scarcely sufficient to give specific 

 rank to P. Endlicheri. Further small diiferences also exist in the foliage. 

 In the Norfolk Island plant the branchlets and petioles are glabrous, or 

 provided only with a few sparse hairs on twigs and midrib. In the New 

 Zealand plants these parts are pubescent. In Norfolk Island specimens 

 the lower leaves are larger than those surrounding the tips of the branches 

 or the inflorescence, having the blade 18-25 cm. long and 10-15 cm. broad.
