Mahe : Summit of Mount Sebert at about 540 metres, 

 Thomasset, 33 ; Morne Blanc, Thomasset ; without locality, 

 Gardiner. Silhouette : Very common in various localities, 

 including summit of Mare aux Cochons, 720 metres, Gardiner. 



I have given the whole synonymy, so far as it is known to me, 

 of this singular plant, which has puzzled several writers. Lindley 

 made it the type of his family Brexiacecs, associating with it 

 Boussea, Ixerba, Argophyllum ; and I, failing at first to identify it, 

 named it Thomassetia and placed it in the Ternstroemiacece.

Weihea Thomassetii Hemsl. , sp. n. ; species W. Flanaganii 

 et W. Gerrardii Schinz. (incolae Africse australi-orientalis) simihs, 

 differt folliis majoribus obscure denticulatis, petalis circiter 

 sexfidis et ovario pilis longiusculis erectis parce vestito. 



Frutex praeter flores glaber, ramis lloriferis gracilibus ad nodes 

 manifesto incrassatis, internodiis quam foliis multo brevioribus. 

 Folia opposita, exstipulata, petiolata, coriacea, tenuiuscula, oblongo- 

 lanceolata, absque petiolo brevi 4-6 cm. longa, apice obtusa vel 

 obtusissima, basi cuneata, margine Integra vel, prsecipue supra 

 medium, obscure denticulata ; costa infra elevata ; venae im- 

 mersse, obscurae ; petiolus ssepius circiter 5 mm. longus. Flores 

 vix 1 cm. diametro, in axillis foliorum numerosi, fasciculati, 

 pedicellati ; pedicelli puberuli, juxta calycem articulati, circiter 

 5 mm. longi, basi bracteis 2 concavis fulti. Calyx subcarnosus, 

 pubescens ; tubus brevis, fere hemisphsericus ; lobi saepius 5, 

 valvati, oblongo-lanceolati, 3-4 mm, longi, obtusiusculi. Petala 

 5, angusta, circiter 5 mm. longa, deorsum attenuata, fere 

 unguiculata, apice fimbriata. Discus obsoletus. Stamina 

 circiter 15 ; filamenta filiformia, inter se libera, petala subae- 

 quantia. Ovarium in calycis tubo fere liberum, pihs longis 

 erectis parce instructum, 3-loculare, obscure trilobum ; stylus 

 stamina vix excedens, stigmate obscure trilobo. Ovula in quoque 

 loculo 2, collateralia, ab apice loculi pendula. Fructus ignotus. 



Aldabea : Sheltered places, Thomasset, 224. 



J. M. Hildebrandt's 3202, from Nossibe, collected in 1879, is 

 evidently the same species with somewhat larger leaves. 



The genera Weihea, Cassipourea, and Dactylopetalum are very 

 closely allied, and an examination of the whole of the species 

 might lead to changes in their delimitation.
