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 : — 



Henslowia, Wall. 



Dioica. Mas : calyx suburceolatus, 5-partitus ; laciniis oestivatione apertis. 

 Corolla nulla. Stamina 5, calycis sinubus inserta ; filamentis per sesti- 

 vationem introflexis, demum erectis longeque exsertis ; antheris termi- 

 nalibus, 2-locularibus, loculis angustis distantibus longitudinaliter de- 

 hiscentibus. Ovarii rudimentum centrale, biloculare. Foem. : calyx 

 fere ut in mare. Stamina abortiva 5. Ovarium liberum, biloculare, 

 polyspermum. Stylus filiformis. Stigma oblongum, peltato-capitatum. 

 Ovula indefinite numerosa, placentae axili afRxa. Capsula supera, bi- 

 locularis, bivalvis ; valvis medio septiferis, mediante stigmate persis- 

 tenti connexis. Semina plurima, minuta, reticulata, apiculata, placentae 

 transversim affixa, dorso secus racheos directionem cristata ; albumen 

 nullum ; cotyledones parvae ; radicula ratione cotyledonum longa, cla- 

 vata, hilum spectans ; plumula inconspicua. — Arbores; raims oppositis 

 determinate ramosis ; foliis oppositis, exstipulatis, integris ; racemis|?a- 

 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 Lythrariece and Melastomacece, 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- 

 strcemiacecE, as follows : — 



Gen. Erythrochiton, Griff,* 



Flores dioici, bibracteolati. Calyx inferus, profunde 5-partitus. Petala 

 5, hypogyna, libera, sepalis opposita. Stamina indefinita, hypogyna, 

 multiplici serie. Antherce adnatae, truncatae. Ovarium 2-loculare, 4- 

 ovulatum. Styli2. Stigmata 2, remformia, foliacea. jBacca supera, 

 2-loculavis, 2-4-sperma. Semina pendula, albuminosa. Embryo cur- 

 vatus. — A.Yhor mediocris ; foliis stipulatis, perennatitibus, integris; pe- 

 duncidis extra-axillaribus ; floribus solitariis ; facie quodammodo Ca- 

 melliae. 



Erythrochiton Wallichianum. 



Hab. in sylvis secus littora Insulae Madamacan, Mergui proximae ; 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 Rox^ 

 burghii. Wall. MSS., formerly called by Mr. Brown Wahlenbergia),
