58 RUTACEvE. [Xanthoxylum. 



1. X.nitidum, DC. Prod. i. 727; {Bot. Mag. t. 2558?) A woody 

 climber, glabrous in all its parts ; the young branches, petioles, and midrib of 

 the leaflets more or less armed with small hooked prickles. Leaves pinnate, 

 with a common petiole of 3 or 4 in. Leaflets 3 to 7, oval-oblong, usually 2 

 to 2^ in. long, obtuse or shortly acuminate, coriaceous and shining, rounded 

 at the base, with very short petiolules. Flowers small, in sessile axillary oblong 

 panicles, seldom above an inch long. Sepals minute. Petals 4, about 1 line 

 long, distinctly imbricate. Stamens longer. Carpels 4, spreading, hard and 

 wrinkled when dry, near 3 lines broad. 



Rather abundant in ravines, Champion and others. Found also about Macao, but not 

 known out of S. China. It is possible that the plant figured in the ' Botanical Magazine' may 

 be a form of the following species. 



2. X. cuspidatum, Champ, in Kew Journ. Bot. iii. 329. A glabrous 

 woody climber, nearly allied to the last species, of which it may possibly prove 

 to be a variety, but the foliage is different. It is less prickly, the common 

 petioles are usually 6 to 8 in. long, or even more ; the leaflets 15 to 25, with 

 a long obtuse point, and narrowed at the base into a much longer petiolule. 

 Axillary panicles short, branching from the base. Flowers of X. nitidum. 



Less common than X. nitidum, and rather local, Champion, frequent in ravines, Wilford, 

 also Hance and Wright. Not known from elsewhere. 



3. X. Avicennse, DC. JProd.i. 726. An erect glabrous shrub. Prickles 

 few and small, curved upwards on the branches, few or none on the petioles. 

 Leaves pinnate, with a common petiole of 3 to 5 in. Leaflets 7 to 13, obliquely 

 obovate or oblong, or rarely almost lanceolate, usually obtuse, narrowed at the 

 base into a petiolule, slightly undulate or almost crenate at the edge. Pani- 

 cles loosely trichotomous, or 2 or 3 times umbellately divided, nearly as long 

 as the leaves, on a peduncle of 2 to 2£ in. Petals 5, slightly imbricate, about 

 1 line long. Carpels 2, when ripe about 2 lines diameter. Seeds black and 

 shining as in the two last species, but smaller. — X. lentiscifolium, Champ, in 

 Kew Journ. Bot. iii. 329. 



On Mount Gough, Champion. Ravines and hillsides, near their tops, Wilford. Also in 

 other parts of S. China, and in the Philippine Islands {Cuming, n. 1622). 



2. EVODIA, Forst. 

 (Boymia, Juss. Philagonia, Hook.) 

 Characters of Xanthoxylum, except that the petals are valvate in the bud, 

 or overlap each other but very slightly; the ovules are usually superposed, and 

 the leaves always opposite. The species are all unarmed. 

 A small tropical Asiatic genus. 



Panicles large, terminal. Leaflets 3 to 7, pinnate 1. E. meliafolia. 



Panicles small, axillary. Leaflets 3, digitate 2. E. triphylla. 



1. E. melisefolia, Benth. A tree, glabrous in all its parts, and without 

 prickles. Leaves opposite, pinnate, with a common petiole of 3 to 5 in. 

 Leaflets 3 to 7, on long petiolules, ovate, acuminate, 2 to 3 in. long, thin, 

 shining above, pale or glaucous underneath. Flowers very numerous, in a 

 broad terminal corymb or trichotomous panicle. Petals 4 or 5, about ] \ lines 

 long, very nearly valvate. Stamens scarcely longer, the filaments hairy inside.
