NEW AND RARE MALAYAN PLANTS. 11 



first by Oliver, Jouni. Linn. Soc. V. Suppl. il. 37, and later by 

 Hooker in the Flora of British India and King in the Mate- 

 rials who have followed Oliver's classification, into three species 

 only G. pentaphylla, Correa, the Limonia pentaphylla of Retz. 

 and Roxburgh, G. sapindoide-s, Lindl. and 67. puberula, Lindl., 

 the greater number of the Indian and Malayan species being 

 reduced to forms of G. pentaphylla " a very variable and most 

 perplexing species." 



The typical G. pentaphylla is based upon what appears to 

 me a very distinct species which is confined to India, and does 

 not occur at all in our area. After examining the various 

 plants included under the names of this and the other two 

 species, I have come to the conclusion that the various forms, 

 perhaps a little difficult to make out from, poor herbarium 

 specimens can be quite well distinguished into species, and are 

 not really so variable as would at first sight appear.

A short stiff shrub about 5 feet tall, with thinly coriaceous 

 1- to 3- foliolate leaves, elliptic lanceolate or oblanceolate, nar- 

 rowed to the base, shortly blunt api dilate; nerves very fine, 

 nervules nearly as conspicuous, usually distinctly gland-dotted, 

 4 — 5 in. to 6 in. long and 1.5 in. wide; petiole 1 — 2.5 in. long, 

 petiolule .1 in. long. The panicles are axillary and terminal, 

 erect and spike-like about .5 to 2 in. long, the peduncle .1 — .75 

 in. long, but occasionally much longer. The flowers fairly 

 numerous, are sessile or nearly so, .1 in. long. Sepals ovate 

 acute, stiff; petals about twice as long, oblong obtuse. Sta- 

 mens with linear-subulate filaments and very small anthers 

 elliptic or elliptic lanceolate. Ovary 3 — 4-lobed, flask-shaped 

 on a small disc, papillose, glabrous. Fruit as big as a pea, pale 

 pink, translucent. 



This plant does not appear to be very common in the 

 Malay Peninsula, but I have it from Tanglin in Singapore 

 from the heaths in Setul, and Kampongs at Kota Bahru, 

 Kelantan. 



It is abundant in Hongkong, and Java, Bandong (For- 

 bes 1215) : and also occurs in Dutch Borneo, Banjermasin 

 (Motley 271), British North Borneo (Fraser) : Philip- 

 pines '(Cuming 1200; Loher 215), Manila (Merrill 112778). 



The form with unifoliolate leaves, has usually stiffer and 

 larger leaves and is probably the G. lanceolata, Spreng. It 

 occurs also in French Guyana (Glycosmis americana, Sagot) 

 and Jamaica. " According to Dr. Broughton it was introduced 

 into Jamaica from England under the name of Mandarin 

 orange in 1788 by Hinton East, Esq." (note in Herb. Kew). 

 These American forms, undoubtedly both introduced, resemble
