ting from the mesocarp and enveloping the seed. SEED solitary by arrest, inverted, 

 covered with the remains of the endocarp and placenta, and accompanied by the 

 arrested ovules ; albumen fleshy. EMBRYO straight, axile ; cotyledons linear or oblong, 

 convex on their dorsal face, and shorter tha n the radicle, which is superior. 



TRIBE I. SANTALE^l.

 middle of the perianth-lobes. 



PRINCIPAL GENERA. 



Quinchatnalium. Osyris. Choretrum. Arjoona. 



Pyrularia. Comandra. Leptomeria. Nanodea. 



Henslovia. Thesium. Santalum. Myoschylos. 



TRIBE II. ANTHOBOLEJE. 



Flowers $ , polygamous or dioacious. Ovary adherent at the base only. 

 Stamens inserted at the base of the perianth-lobes. [All Australian]. 



PRINCIPAL GENERA. 

 Anthobolus. Exocarpus. 



[To these tribes should be added that of Buckley ece, Alph. D.C., which is founded 

 on the United States genus Buckley a, a plant with a double perianth to the j 

 flowers, and a single one to the $ .] 



We have indicated the affinity of Santalacecs with Loranthacea, Proteaceee, Elceagneca, and Thymelea: 

 (see these families). They also approach the apetalous Combretacece in the simple perianth with valvate 

 aestivation, the stamens opposite the perianth-lobes, the inferior ovary 1-celled and crowned by a disk, &c. 

 [They approach still nearer to Olacinece and Cornea, differing from the former in the superior ovary, and 

 from the latter in being monochlamydeous and 3-ovulate.] 



Santalacece are dispersed over the temperate and tropical regions of the whole world, especially in 

 Asia, Europe, South Africa, and Australia ; they seem to be absent from tropical America and tropical 

 Africa. They are herbaceous in Europe, Central Asia, and South America (where Nanodea attains 

 the height of only 6 or 9 feet), suffruticose in the Mediterranean region, generally arborescent in 

 Asia and Australia as well as in the northern temperate regions of the New World, and sometimes 

 parasitic in Asia (Henslovia). 



Very little is known about the properties of Santalacece. The most remarkable are the species of 

 Santalum, especially album, a large tree of South Asia, the aromatic and scented wood of which was 

 formerly celebrated medicinally, and is still used [as a medicine in India and] in perfumery and cabinet 

 making [as are various Pacific Island species of this genus]. The roots and fruits of Osyris and TJwsium 

 are astringent. The leaves of O. nepalensis are used as tea. An infusion of the leaves of MyoschUos 

 oblongus, the Senna of the Chilians, is purgative. The Peruvians eat the seeds of Cervantesia tomentosa 

 like filberts ; those of Pyrularia pubera, which grows on the mountains of Carolina and Virginia, yield a 

 fixed and edible oil.
