placing in a different genus to Stadmama, the fruit is formed of one 

 to three berries also opening longitudinally, but they are loaded with 

 tubercles or prickles and the seed is only incompletely surrounded 

 by the aril. The Spanogheas, Asiatic species, can no longer be 

 separated generically from Nephelium. The fruit, more or less deeply 

 lobate, is indehiscent or opens cross ways or obliquely at maturity. 

 The aril only partially envelopes the seed, and the embryo is bent. 

 Pometia also constitutes accord- 

 ing to us a section of the same »'"'"' ^^"^"""'^ "'^'"''■ 

 genus. The flowers have from 

 four to eight stamens and a fruit 

 whqse seed, surrounded by a mu- 

 cous aril, contains a condupli- 

 cate embryo. Like all the species ^'^- '''■ «-^ '^- l^[ Z^T^l 

 of Nephelium which have been 



enumerated, these trees from India and the isles of the Pacific Ocean 

 have^compound-pinnate leaves, whose inferior folioles are but little de- 

 veloped, orbicular, stipuliform. In the Pappceas, on the contrary, 

 plants from the Cape of Good Hope, whose flowers are also those 

 of Nephelium J and which we also include in that genus, the leaves 

 are simple, and the seeds loosely surrounded by an aril (flg. 359, 

 360) have a conduplicate or convoluted embryo. Zerospermum, a 

 tree from the Indian Archipelago, may be defined as a Nephelium 

 with tetramerous flowers, thick and developed stigma, and fruits 

 whose tubercular berries contain an exarillate seed. In Deinbollia, 

 consisting of trees, often hairy, from tropical "Western Africa, the 

 flowers, constructed like those of Euphoria, with large imbricate 

 sepals, have expanded petals, lined inwardly by scale or 

 bunch of hairs, and usually from twelve to twenty-five stamens. 

 The 1-3- lobate fruit, the seed and the aril are those of Nephelium. 

 Podonephelium, a tree from Oceania, is an apetalous Nephelium whose 

 carpels are borne at the summit of a long and thick gynophore. 

 The Heterodendrons, Australian shrubs, have also the flowers of 

 Nephelium, apetalous, with 6-16 stamens and a 2-4-locular ovary, a 

 dry fruit, lobate, and arillate seeds, containing an embryo with 

 flexuous cotyledons. But their aspect is that of an Olive ; they 

 have simple or pinnate leaves, coriaceous, linear, or oblong, and 

 flowers arranged in solitary or double clusters. In the Capuras,
