This species is widely distributed in the Philippines at low altitudes, 
extending from northern Luzon to southern Mindanao. Blanco's specific 
name appears to be the oldest valid one for the species, both Paliurus 
perforatus and P. dubius being manifestly the same species. Burma to 
southern China, southward to Java.

TRISTELLATEIA Thouars. 
Tristellateia australasiae A. Rich, presents an interesting case of 
synonymy on account of the approximately simultaneous publication of 
Platynema laurifolium Wight & Am., which all authorities agree to be an 
exact synonym of Richard's species. The synonymy is as follows: 
TRISTELLATEIA AUSTRALASIAE A. Rich. Sert Astrolab. Atlas (1833) 
pi. 15, (T. australasica Auct.) 
Gaertneria laurifolia Wall. Cat. (1832) no. 7265, nomen. 
Tristellateia australis A. Rich. Sert. Astrolab. (text) 2 (1834) 38; 
Sprague in Curt. Bot. Mag. IV 6 (1910) t. 833^. 
Platynema laurifolium Wight. & Arn. in Edinb. New Philosoph. 
Journ. (Apr.-July, 1833) 179; Prodr. (1834) 107. 
Hiraea reclinata Blanco FL Filip. (1837) 378, non Jacq. 
Tristellateia malintana Blanco 1. c. ed. 2 (1845) 267. 
As there appears to be no means of determining the relative status of 
the publication of Richard's and Wight & Arnott*s names as to priority, 
the former, being in general use (as T, australasica) is here accepted. 
Authorities generally agree that the volume of plates accompanying 
Richard's "Sertum Astrolabianum" was published in 1833, and the text, 
volume one in 1832, volume two, 1834; the plate of Tristellateia australasiae 
shows a complete dissection of the flower, and is hence a valid publication. 
As to Platynema laurifolium Wight & Arn., this was based on Gaertneria 
laurifolia Wall. (1832), and hence this name is the oldest, although un- 
fortunately the "publication" in Wallich's "List" is only a now^n nudum 
and has no standing; in the "Edinburgh New Philosophical Journal" the 
genus Platynema is described, but the species, P. laurifolium, is enumerated 
without description; the specific description was published in the following 
year.
