part que je dois a Mr. Ridley) nous croyons devoir renoncer 
au choix entre Jes deux noms de variété, et comme il s’agit 
pour nous d’une espéce distincte, lui donner le nom de celui 
qui sen est occupé le plus. 
A plusieurs reprises depuis 1898 Mr. Ridley m’a envoyé cette 
curieuse plante, en apparence un nanisme de l’enorme P. co- 
ronarium, dont les frondes, de quelques métres de longueur, 
retombent en paquets pesants et en dichotomies multiples des 
branches des Shorea et des Dipterocarpus de la Malaisie, de 
Mergui et de l’Annam francais (1. P. Cadiére) & travers les 
Iles de la Sonde aux Philippines. 
Voici ce que Ridley dit de sa plante: 
A much smaller plant with the fertile fronds erect and short. 
Sterile ascending fronds a foot long and as wide, very strongly 
ribbed, rounded in outline, and dotted over with hairs arranged 
stellately. 
Fertile fronds stiffly erect 8 to 18 inches long, 8 inches across, 
dichotomously branched, the tips of the branches rounded; 
fertile lobe spathulate or obovate, pedicelled 2—5 inches long 
and as wide in the widest part. Singapore, Buckit Timah on 
very lofty branches of trees (Ridley 10830). 
'. Bishop Hose first pointed out this plant to me some years 
ago on perfectly inaccessible boughs of a lofty Shorea tree, 
100 feet or more from ‘the ground. There are a number of 
plants on the boughs, all are quite similar and there are no 
typical specimens of Platycerium biforme on the tree, tough 
it is abundant in the surrounding forests. I have only been 
able to obtain fallen fronds. 
Mr. C. I. Matthew took specimens to Kew and Mr. Wright 
notes on them as follows: : 
»I do not think this can be separated as a distinct species 
from Platycerium biforme BL, but is a form produced by 
growing in exposed situation and is worthy of a varietal 
shame. It has also been collected in Borneo by Motley who
