TWO NEW GENERA OF ASCLEPIADE^. 



By R. Schlechter. 



(Plate 352.) 



SYMPHYTONEMA Schltr., gen.nov. Calyx 5-paititus, seg- 

 mentis brovibus suborbicularibus obtusis, intus squamis 5 alternan- 

 tibus, bene couspicuis, suborbicularibus, ornatus. Corolla alte 

 5-fida, lobis lanceolatis retlexo-patulis, corona foliolis corollse ad- 

 natis, basi in annulum brevem conuatis, apicibus libetis 5, cum 

 corollfe lobis alterniuitibus, erectis, lanceolatis npice setaceo- 

 elongatis, exappendiculatis. Authera subordinis {Pi-riploceanim) 

 sagittato-rhomboidea, apice obtusa exappendiculata. Polliuia granu- 

 losa spatliulata, apice rotundafca. Stigma breviter conicum, basi 

 margine incrassatum. 



Symphytonema madagascariense Schltr., sp. n. Planta 

 volubilis, ramosa, alte scandens, omnino glaberrima ; ramulis 

 teretibus remote foliatis ; foliis erecto-patentibus patulisve lineari- 

 lanceolatis vel lanceolato-ellipticis, acutis vel subacuminatis, basi 

 angustatis, brevissime petiolatis, 2-3 cm. longis, medio fere 0-5-1 

 ciu. laiis; floribus extra-axillaribus alternautibus singulis vel in 

 fasciculis 2-3-floris, patulis, breviter pedicellatis; calycis segraentis 

 suborbicularibus obtusissimis, quam corolla duplo brevionbus ; 

 corolla siibrotata lobis lanceolatis vel rarius ovato-lanceolatis 

 acutis, reflexo-patulis, utrinque glabris ; coronge tubo brevi sub- 

 cylindrico, apicibus liberis erectis lanceolatis vel liueari-lanceolatis, 

 apice setaceo-elongatis, inflexis ; antheris e basi breviter stipitatis 

 rhomboideo-sagittatis, apice liuearibus obtusis cohferentibus ; 

 poUiniis e basi longe stipitata suborbiculari-spathulatis, obtusis- 

 simis, marginibus iuvolutis, glandula oblonga, bene conspicua. 



Habitat in Madagascarite parte austro-orientali; scandens inter 

 frutices prope Fort Dauphin, Horens Maio, Scott Elliot, No. 2722 ! 



This new genus is perhaps most nearly allied to Camptocarpus 

 Dene., but differs in the five- not tenlobed corona, and the in- 

 florescence. The diagnosis was written out from Mr. Scott Elliot's 

 specimens in tlie British Museum, which are in good condition, 

 although there are only a few flowers. I have not seen this plant 

 from any other collection, not even in Mr. Baron's, a fact wliich 

 may suggest a very limited geographical distribution. The colour 

 of the flowers seems to have been a dark purple. 



GLOSSOSTELMA Schltr., gen.nov. Calyx 5-partitus, intus 

 basi irregulariter papillis imequilongis ornatus. Corolla alte 5-fida, 

 lobis erecto-patentibus oblongis obtusis. Corona simplex breviter 

 annularis, apicibus liberis, 5, antheris oppositis, erectis, ligulatis, 

 subcarnosis, antherae dorso appressis. Anthera bilocularis, mar- 

 ginibus cartiliigineis bene conspicuis, apice membranacea rotuudata, 

 in stigma inflexa, Integra. PoUinia in quoque loculo solitaria, 

 pendula compressa ; glandula rhomboidea pro magmtudine polluii- 

 orum satis magna, caudiculis deflexis, flexuosis, elongatis. Sti'^ma 

 depressum, margine incrassatum 5-gibbosum.
