EUPHORIA LONGANA. (Nat. order Sapindacese.) 



EUPHORIA. Juss. — GEN. CHAE. Flowers regular, polygamous, sepals 5, distinct, imbricate or valvate in the bud, petals none or as 

 many as sepals, with or without a scale inside, disk annular, stamens 6 to 10, inserted within the disk, ovary 2 or 3-eelled, usually lobed, with 

 1 ovule in each cell, style deeply 2 or 3-lobed, or divided to the base into distinct styles, fruit deeply 2 or 3-lobed, or reduced to a Bingle carpel, 

 the lobe3 usually indehiscent, often tuberculate, seeds enclosed in a pulpy arillus ; testa coriaceous, cotyledons thick. Trees, with the young shoots 

 usually pubescent, leaves pinnate, leaflets as in Neplielium, but in 1 species toothed ; flowers small in terminal panicles. — See Manual under the genus 

 Nephelium. 



EUPHORIA LONGANA. (Roxb.) A rather large tree with a short straight trunk and a dense globular head 

 polyganio-nionaecious, leaves alternate abruptly pinnate 6-10 inches long, leaflets 2-4 pair glabrous above, more or less hoary and 

 glaucous beneath, (as are the young shoots and panicles) coriaceous entire, from ovate-lanceolate to oblongo-lanceolate, often very oblique 

 at the base obtuse or acute at the apex and sometimes mucronate, 2|-9 inches long by f-2^ broad, veins pinnate prominent, petiolules 2-5 

 lines long, panicles terminal and from the upper axils, flowers small pale yellowish-white, male and hermathrodite mixed in the same 

 panicle, calyx deeply 5-parted hoary or downy on both sides, petals 5 inserted between the calyx-lobes and the disk, scaleless, narrow 

 linear-lanceolate, hairy, much longer in the male than in the hermathrodite, stamens hairy generally 10 in the male and 8 in the herma- 

 throdite (sometimes only 8 and 6), in the former longer than the petals, in the latter with very short filaments, ovary hairy 2-3 lobed, 

 stigmas the same number, fruit of 1-3 (generally only 1) cocci about the size of a cherry, from nearly smooth or more or less hoary or 

 scabrous to grossly tuberculate and warted, aril edible. — Scytale longana, Roxb. Fl. Ind. ii. p. 270. Euphoria longana, Lam. BO.

A handsome tree, common in all the jungles (up to 3,000 feet) on the west side of the Madras Presidency, in Mysore Bombay, 

 Eastern Bengal, Ceylon and in China; the description is drawn up from copious specimens collected in South Canara, the Anamallays, the 

 Sivagherry hills, Courtallum and Ceylon / in S, Canara the tree is called Mai Ahcotd, at Courtallum Poond, in the Bombay Presidency Wumb, 

 in Ceylon Mora ; the Chinese name is Zongan (hence Roxburgh's specific name, he having first received the tree from China) ; the wood is said to 

 be hard, close grained and white and worth attention, but I have not seen it in use ; the succulent aril of the seed is an agreeable acid and something 

 like the Litchi. As a genus it should not 1 think be kept distinct from Nephelium. The drawing is from a specimen gathered on the Tinnevelly 

 mountains at 2500 feet elevation, and the leaves are more acuminated than in most of the for nw- Analysis is given of male and hermathrodite 

 flowers, the former with 10 stamens, the latter with 8 only. 



Analysis, 



1. A male flower showing 10 stamens, petals and stamens, much larger than the calyx.
