4&6 SYSTEMATIC BOTANY. 



fructu pistilliformi sicco. From the Balanophorese, Griffith excludes Sar- 

 cophyte, the affinity of which is unknown, perhaps tending towards the 

 Urticaceee, and Mystropetalon Harv., which exhibits some affinity to Cyno- 

 morium alone, and must be regarded either as a distinct family (planta sui 

 ordinis), or as a doubtful form of Loranthaceae, with a homogeneous embryo. 

 Both genera are accurately described from Harvey's specimens. The de- 

 scription of Sarcophyte differs very considerably from that usually given 

 (thus : columns stamineae 3 ( 4), antheris indeftnitis unilocularibus stipitatis), 

 but Endlicher has already made the same remarks regarding the structure of 

 the stamens. 



THYMELEACEJS. New genera from Guiana, in Schomburgk's collection : 

 Lasiadenia Benth. (Lond. Journ. of Bot. 1845, p. 632), and Goodallia Benth. 

 (ib. p. 633). 



SANTALACE.E. Griffith states, that in Osyris the development of the ovule, 

 which in other respects resembles that of Santalum, the embryo-sac grows out 

 from the nucleus, and, as in Avicennia, the albumen is only deposited in this 

 projecting portion (Proceed, of Linn. Soc., Nov. 1844, in Ann. Nat. Hist., 

 xv, p. 197). 



LOEANTHACE.E. R. Brown forms the Myzodendrese from Myzodendron, 

 and gives them the following characters : Ovula 3, in apice placentce cen- 

 tralis suspensa, unum fertile (approximating the Santalaceae in this character) ; 

 flos $ nudus ; appendices plumosa in et embryo indivisus, radicula ex albu- 

 mine exserta (Linn. Trans., xix, p. 232.) 



POLYGONACE.^:. New genera: Pteropyrum'Ss^. Sp. (Illustr. or. 1. 107-9), 

 endemic in Persia and Arabia ; Thysanella Gray (PL Lindheimer) = Poly- 

 gonum fimbriatum ; Symmeria Benth. (Lond. Journ. of Bot., 1845, p. 630), 

 a dioecious tree from Essequibo. 



CHENOPODIACE^;. Sarcobatus N., is figured in the American edition of 

 Fremont's Exploring Expedition, as Fremontia (tab. iii). New genera: 

 PterocJiiton Torr., Ere. (ibid. &c. p. 57), from the west of North America ; 

 Physogeton and Halothamnns Jaub. Sp. (111. or. t. 135-6), from Persia. 



URTICACEEE.. Gasparrini separates the following species generically from 

 Ficus (Ann. Sc. nat., iii, p. 338-48) : Tenorea=F. stipulata ; Urostigma 

 = F. religiosa and six other species ; Visiania = F. elastica ; Cystogyne = 

 F. leucosticta ; Galoglychia = F. Saussureana, D. C. and galactophora Ten. ; 

 Covellia = F. ulmifolia. He also regards F. Carica, at the same time attri- 

 buting too much weight to the circumstance of Cynips Psenes living only on 

 the wild fig-tree (Caprificus), as consisting not merely of two different species, 

 but two genera, which he distinguishes as Ficus = F. Carica fcemina L. and 

 Caprificns = F. Carica androgyna. 



SATJRUBACE^. Decaisne describes SpatUum chinense Lour., and forms 

 the genus Gymnotheca from it (Ann. Sc. nat., iii, pp. 100-2). 



Miquel has published a very copious supplement to his
