Ovaria 2, distincta. Placenta in quoque loculo due, suture: utringue affix. Ovula numerossima, 
amphitropa. Stylus apice appendice umbraculiformi reflexo lobato coronatus, stigmate pulvinato 
breviter bilobo. Frutices vel arbores, ramulis apice bifurcatis vel dichotomis. Folia opposita. 
Racemi breves, pauciflori, in bifurcatione ramulorum vel in axillis superioribus solitarii, Corolle 
magne, speciose, albz vel flave. Genus Odontadenic affine. 
S. glabra. Rami juniores compressi, mox teretes, apice bifurcati. Folia 5-6 poll. longa, 24-3 poll. lata, 
acumine brevi acutiusculo terminata, basi obtusa, membranacea, utrinque viridia, subtus pallidiora, costa media 
venisque primariis utrinsecus 12-16 subtus prominulis, eglandulosa, petiolis 2-4 lin. longis margine angusta sub- 
connexis. Racemi in bifurcatione ramorum foliis breviores 3-5-flori. Pedicelli inferiores 4-6 lin. longi, 
superiores brevissimi, singuli bractea minuta squameeformi subtensi. Bractew 2 et sepala 5 gradatim accrescentia 
a bractea exteriore subfoliacea appressa vix 3 lin. longa, in sepala interiora 2 vel 3 subeequalia, valde imbricata, 
fere pollicaria, apice obtusa truncata membranacea. Corollw sub-3-pollicares, extra calycem in faucem ample 
campanulatam dilatata, lobis latis rotundatis. Glandule calycis ultra 100, breves, lineares in verticillum densum 
circa corollam dispositee. Nectarium breve, annulare, uti in speciebus sequentibus lobatum videtur, lobis brevibus 
latis (3 vel 52). Ovaria a basi distincta.

The size and form of the flowers in the above three species are those of a 
Cerbera or a Thevetia, from both of which, however, they widely differ in the 
calycine glands, and from the latter in the ovary ; in many points also there is a 
considerable degree of affinity with Odontadenia, but that genus reve. has not the 
remarkable calyx and glands of Stemmadenia. A fourth species of the genus 
allied to §. mollis, with the same structure and pubescence, but longer petioles, 
and some other points of difference, has been gathered by Galeotti (n. 1632), ig
