ornamented with dark brown streaks and strains, fairly hard in texture 

 and taking a good polish. Mr. F. Penney obtained a considerable quantity 

 of the wood from Siamese territory North of Province Wellesley, from 

 which he had made furniture, boxes, etc., which was very highly valued 

 on account of its beauty. He obtained also leaves and fruit of the 

 tree. For the flowers I am indebted to Mr. H. C. Robinson, who met 

 with it in Upper Perak. 



It differs from other species of the genus in the greater size of the 

 leaves, the conspicuously stalked ovary, and the remarkable fruit which 

 resembles a citron. The rind has a bitter terpentiney flavour, and the 

 comparatively scanty pulp is quite tasteless. The fruit is so entirely 

 different from that of any other species of the genus that the plant 

 might almost be separated generically. 



In the introduction to the fourth series of New or Rare 

 Malayan Plants 6 the following paragraph occurs: 



The well known furniture wood Katinga from the Siamese borders 

 has long been prized and I obtained leaves and a fruit some years ago 

 from Mr. F. G. Penney, who had a fine collection of furniture made from 

 its wood. A number of young plants were raised in the Botanic Gardens, 

 and I lately obtained specimens shewing parts of the flower from Mr. 

 H. C. Robinson. It proves to be a Murraya allied to the well known 

 Kamuning wood, so much valued for the handles and sheaths of Krises. 



As Ridley did not have good flowering specimens or fresh 

 fruits the original description should be supplemented in some 

 particulars and emended in others. The following notes were 

 made from the flowering specimen and fruit collected in March, 

 1918, from the tree cultivated in the Singapore Botanic Gardens. 



The leaves of fruiting twigs are sessile, pinnate, with 6 to 8 

 alternate leaflets. The petiole is very short or wanting, the 

 rachis 10 to 15 cm long, narrowly winged, the wing increasing 

 in width gradually up to the point of attachment of the leaflets, 

 then suddenly diminishing. The leaflets are very unequal in size 

 and shape, the basal ones — sometimes a pair nearly opposite — 

 being very small, 5 to 10 mm in diameter, and very broad, often 

 suborbicular. The lateral leaflets increase rapidly in size up 

 to the penultimate, and at the same time become narrower and 

 more pointed, becoming also somewhat inequilateral. The penul- 

 timate leaflet is 70 to 80 by 20 to 30 mm, rhomboid-lanceolate, 

 subacuminate at the apex but with the very tip bluntly rounded ; 

 the base is cuneate. The terminal leaflet is like the penultimate 

 in shape but symmetrical, 80 to 100 by 30 to 35 mm. The 

 margins of the leaflets are wavy, sometimes slightly serrate. 

 The very young leaves, like the young twigs, are minutely 

 pubescent, but the older leaflets become nearly glabrous. The
