Native of Queensland. 



Nat. Ord. Convolvulace^:. — Tribe Cojjvolvule^:. 

 Genus Ipom^ia, Linn.; {Benth. et Hook.f. Gen. PI. vol. ii. p. 870.) 



IPOM.&A (Speciosse) Robertsii; tota pubescenti-tomentosa, caule gracili volubili, 

 foliis gracile petiolatis late ovato-cordatis acuminatis integerrimis utrinque 

 stellato- v. squamuloso-tomentellis sinu lata, floribus solitariis, pedunculo 

 petiolo sequilongo, sepalis J-pollicaribus oblongo-rotundatis glabratis, corolla 

 3-pollicari infundibular! alba radiis 5 roseis tubo medio obscure ventricoso, 

 margine undulato, staminibus tubo inclusis, filamentis basi villosis, stylo pa roe 

 piloso, stigmatis 2-lobi lobis globosis. 



A very beautiful and apparently undescribed species, 

 nearest to I. velutina, Brown, of the Gulf of Carpentaria, 

 but differing in the acute leaves which are stellately hairy 

 on the upper surface, in the flowers being always solitar}^ 

 (though a joint about their middle suggests the possibility 

 of the peduncle being sometimes two- or more-flowered), 

 and in the much larger sepals. Seeds were sent to the 

 Royal Gardens in 1883 by Mr. G. F. Roberts (Nursery- 

 man of Kew, Melbourne), from which the plant here figured 

 was raised. It flowered in the Lily-house in July of last 

 year, and is perennial. 



Desor. Stem very slender, twining, clothed as are the 

 petioles and leaves with a soft subtomentose pubescence. 

 Leaves three to four inches long, membranous, broadly 

 ovate-cordate, acuminate, with a broad open sinus at the 

 base, dull green, pubescence more or less stellate on both 

 surfaces, and squamulose on the upper ; nerves eight to 

 ten pair, spreading ; petiole one and a half to two inches 

 long, slender, pubescent. Peduncles axillary, solitary, one- 

 flowered, jointed below the middle, the lower part pubescent, 

 the upper gradually thickened upwards, nearly glabrous. 

 Sepals broadly oblong or almost rounded, one-third to 

 half an inch long, obtuse, green with white margins, nearly 

 glabrous. Corolla three to four inches long ; tube elongate, 

 funnel-shaped and slightly tumid below the middle, limb 

 august 1st, 1887.
