A magnificent cultivated species, mucb resembling 0. speciosa. Its oblong leaves 

 bave a narrow obtuse acumen, become gradually narrower from the middle towards the 

 base, where they are slightly cordate, have many diverging nerves, are 14 in. long, 5| in, 

 broad, on petioles 7 lines long ; its panicle is copiously flowered ; pedicels 6-8 lines 

 long ; sepals oval, subacute, 4 lines long ; tube of corolla funnel-shaped, 2 in. long, 

 widening in the mouth to a breadth of near 1 inch, the border expanding to a diameter 

 of S^ in., the segments being dolabriform, dextrorsely convolute, 1^ in. long and broad ; 

 lobes of disk denticulate, enveloping the ovaries.
