pointed out by Mr. Brown, that the ovarium of dicotyledonous 
plants, when single, never adheres to the calyx. 
In the next paper, Mr. Griffith makes some additions to our know- 
ledge of the genus Henslowia, which he characterizes as follows :-— 
Henstowia, Wail. 
Dioica. Mas: calyx suburceolatus, 5-partitus ; laciniis zstivatione apertis. 
Corolla nulla. Stamina 5, calycis sinubus inserta ; filamentis per esti- 
vationem introflexis, demim erectis longéque exsertis ; antheris termi- 
nalibus, 2-locularibus, loculis angustis distantibus longitudinaliter de- 
hiscentibus. Ovarii rudimentum centrale, biloculare. Fam.: calyx 
feré ut in mare. Stamina abortiva 5. Ovarium liberum, biloculare, 
polyspermum. Stylus filiformis. Stigma oblongum, peltato-capitatum. 
Ovula indefinité numerosa, placente axili affixa. Capsula supera, bi- 
locularis, bivalvis; valvis medio septiferis, mediante stigmate persis- 
tenti connexis. Semina plurima, minuta, reticulata, apiculata, placenta 
transversim affixa, dorso secus racheos directionem cristata; albumen 
nullum ; cotyledones parve ; radicula ratione cotyledonum longa, cla- 
vata, hilum spectans; plumula inconspicua.—Arbores ; ramis oppositis 
determinate ramosis ; foliis oppositis, exstipulatis, integris ; racemis pa- 
niculatis ; floribus minutis, inconspicuis. 
A part of the additional information on this curious genus has 
already appeared (on Mr. Griffith’s authority) in Prof. Lindley’s 
‘Natural System of Botany.’ After noticing the Combretaceous 
habit of the male tree when in full flower, Mr. Griffith adds, that it 
can scarcely be doubted that it is the type of a distinct order, and 
hazards an opinion that its true situation in the natural system will 
be found between Lythrariee and Melastomacee. He observes also 
that the ovula present the peculiarity of the raphe running along 
their upper or under faces, independent apparently of any twisting 
of the short funicle. 
Mr. Griffith next characterizes a new genus of the order Tern- 
stremiacee, as follows :— 
Gen. Erytsrocuiton, Griff,* 
Flores dioici, bibracteolati. Calyx inferus, profundé 5-partitus. Petala 
5, hypogyna, libera, sepalis opposita. Stamina indefinita, hypogyna, 
multiplici serie. Anthere adnate, truncate. Ovarium 2-loculare, 4- 
ovulatum. Styli2. Stigmata 2, reniformia, foliacea. Bacca supera, 
2-locularis, 2-4-sperma. Semina pendula, albuminosa. Embryo cur- 
vatus.—Arbor mediocris ; foliis stipulatis, perennantibus, integris; pe- 
dunculis extra-axillaribus; floribus solitariis; facie qguodammodo Ca- 
melliz. 
ErytTHrRocHIton WALLICHIANUM. 
Hab. in sylvis secus littora Insule Madamacan, Mergui proxime ; lect, 
mense Decembris 1834. 
Mr. Griffith adds in a note, that to this genus Hopea eglandulosa, 
Roxb., which Mr. Colebrooke in a MS. note in Roxburgh’s MS. 
Synopsis stated long ago not to belong to Hopea (Sarcostigma Row- 
burghii, Wall. MSS., formerly called by Mr. Brown Wahlenbergia),
