 adnatis : basi recurva. Cur. subcampanulata. 



1. Froccrn. Persia. Shrub.

 10-partita ; laciniis alternis minutis. Cor. patens. 

 Follicnli rimentacei. 



1. Undulatum. 2. Grawliflorum. 



Both of these species are given by Willdenow un- 

 der Asclepias, with the same specific names. See 

 Brown, Wern. Trans, i. p. 27. 

 CLXXII. GoMPHOCARi'L's. Asclepiadea. Masses

 CLXXI ILGoxoLODUs, or GONOLOBIUM. Asclepia- 

 dea. MOSSCB pollinis Ifeves, 10, transversse. Cor. 

 subrotata. Sent, comosa. 



This new genus is formed from the genus CYNAN- 

 CHUM. " Cynanchum maritimum, Linn." says 

 Mr Brown ; " suberosum, Linn. ; crispiflorum, 

 Hort. Kent, belong to this genus j and I sup- 

 pose also C. plantflorum, graiicliflorum, rostra- 

 turn, nignnn, racemo.ium, Carolinense, obliijutim, 

 hirlum, proslratum, and undulaium, of Willde- 

 now's Spec. Plant. : These, however, I have not 

 determined, and the whole genus requires to be 

 re-examined." See Wern. Trans. \. p. 24'. 

 Persoon includes under his subgenus GONOLOBIUM, 



1. Mitcrophyllum. Woods of Carolina. (Mi- 

 chanx ) 



2. Hirsulum. Woods of Carolina. 



3. Lceve. Banks of the Mississippi. 



4. Obtusifolinm. ( In the Herbarium of Richard. ) 



5. Planiflorum. Carthagena. 



6. Album. Peru. (Cavrinilles.') 

 CLXXIV. MARSDENIA. Asclepiadea. Massee polli- 

 nis Izves, 10, erects. Anth. membrana terminate. 

 Corona staminea 5-phylla : foliolis compressisj in- 

 divisis, intus edentulis. 



1. Velutina. New Holland. 



2. Tinctoria. Sumatra. 



3. Viridiflora. New Holland. 



4. Clausa. Jamaica. 



5. Suavcolens. New Holland. 



6. Ciiierascens. New Holland. 



7. Erecla. (Cynanchum erectwri). 



8. Rostrata. New Holland. 



" This genus," says Mr Brown, " differs from 

 Pergular/a, chiefly in the want of the inner la- 

 cinias of the corona : It is therefore an arbitrary 

 separation, made principally to obtain clearer 

 characters for both. The two species (7, 8) 

 with an elongated stigma are perhaps not truly 

 of this genus, but, if separated from it, must 

 form each a distinct genus." ( Wern. Trans. ) 

 CLXXV. HOYA. Asclepiadea. Masses pollinis lae- 

 ves, 10, erecto-conniv^ntes. Anth. membrana ter- 

 minate. "Corona staminea 5-phylla : Foliolis de- 



pressis, angulo intcriore producto in denteni an- Class 

 there incumbentem. Cor. rotata. 



1. Carnnsa. Tropical parts of Asia, and in """ 

 New Holland. Shrub. 



2. Viridiflora. Groves of Ceylon. Shmb. 

 Species 1. is the Asclepias carnoxa, and speciea 2. 



the Asclepias votttbms of Willdenow. " Hoya 

 carnosa," says Mr Brown, " probably includes 

 several species, which can only be determined 

 from living specimens : it is also to be consider- 

 ed as the type of the genus Hoya viridiflora, 

 differing in some degree in the structure of its 

 corona, and considerably in habit." (Wern. 

 Trans, i. p. 15.) 



CLXXVI. CEROPEGIA. Cor. tubo e basi ventricosa 

 cylindraceo ; limbi laciniis ligulanbus. Cotitmtttt 

 fructificationis inclusa. Corona slam, duplex, ex- 

 terior abbreviata, 5-loba : interior 5 phylla, folio- 

 lis ligularibus, indivisis, lobis exterioris oppositis. 

 Anth. apice simplices. Massce pollinis erectae, basi 

 affixx, marginibus simplicibus. Stig. muticum. 

 Fo/liculi cylindracei, Iseves. Sent, comosa. (R. 

 Brown, Wern. Trans, i. p. 10.) 

 To this genus belong Sp. 1, 2, 3, 4, 5, 6, of Ce- 

 ropegia, p. 159. ; and also two undescribed spe- 

 cies. 



CLXXVII. HUERVIA. Cor. campan. limbo 10-fido, 

 laciniis accessoriis nanis, dentiformibus. Columna 

 fruclifcationis inclusa. Corona stam. duplex ; ex- 

 terior quinquefida, laciniis bifidis : interior 5-phyI- 

 la, foliolis c basi gibbcsa subulatis, indivisis, laci- 

 niis exterioris alternantibns. Anth. apice simplices. 

 Masses pollinis erectas, basi'affixae, altero margine 

 cartilagineo-pellucido. Stig. muticum. Folliculi 

 subcylindracei, lasves. -Sew. comosa. (R. Brown, 

 Wen. Trans, i. p. 11.) 



Sp. 43 49 of Stapelia, p. 157. belong to this ge- 

 nus. Mr Brown has examined only Sp. 43, 45, 

 46, from which the character is formed. 

 CLXXVIII. PIARANTHUS. Cor. campan. 5-fida, 

 carnosa. Cohimna fruclijicationis inclusa. Corona 

 stam. simplex 5-phylla, foliolis dorso dentatis. 

 Anlh. apice simplices. Massce pollinis erects, 

 basi affixiE, altero margine cartilagineo-pellucido. 



Stig. muticum. Follic. (Wern. Trans, i. p. 12.) 



" The want of the external corona," says Mr 

 Brown, " renders it necessary to separate from 

 Stapelia and Hucrnia this genus ; of which the 

 only two certain species are Stapelia punctala 

 and pulla of Masson." 



CLXXIX. STAPELIA. Cor. rotata, 5-fida, carnosa. 

 Colitmtuifriiclificatwnis exserta. Corona stam. du- 

 plex, utraque in variis varia ; interior quandoque 

 obsoleta. Anth. apice simplices. Masste pollinis 

 basi affixce, altero margine cartilagineo-pellucido.

 comosa. 



Beside several species of the genus STAPELIA, 

 p. 157. this genus contains several unpublished 

 ones in the Banksian Herbarium. See Wern. 

 Trans, i. p. 13. 



CLXXX. CARALLUMA. Cor. rotata, profunde 5- 

 fida. Cohimna fructificationis exserta. Corona 

 stam. simplici serie 10- phylla ; foliolis quinque an- 

 theris oppositis indivisis ; reliquis bipartitis subu- 

 latis. Anth. apice simplices. Mas x<e pollinis erects,
