ally into a deep polished green. Unlike all other Nico- 
tianas in cultivation this does not flower in the open air, 
and it is multiplied by cuttings. 
I have no hesitation in referring N. colossea to Ruiz and 
Pavon’s Nicotiana tomentosa, poorly figured in their great 
work, but of which there are excellent specimens in the 
Kew Herbarium, sent to Sir W. Hooker by Mr. Matthews, 
as a large shrub growing in the Quebrader of Paria 
Mianea in Peru; again from Yucca in Bolivia, Lat. 13° 
S., by Mr. Pentland; and by Lobb from New Grenada. 
It has also been collected by Mandon in the Bolivian 
Andes (No. 448), who describes it as occurring every- 
where in hedges near Sorata, at an elevation of eight 
thousand five hundred to nine thousand five hundred feet 
above the sea. N. tomentosa has been erected into a genus 
(Lehmannia) on account of the form of the corolla, which 
however does not materially differ from that of Nicotiana, 
in which it must remain. 
The plant here figured was obtained from M. Godefroy 
- Leboeut in 1889, and was planted out in the central bed 
of the Conservatory (No. 4) of the Royal Gardens, Kew, 
where it rapidly reached the roof (ten feet), and had to 
be topped, which no doubt accounts for its bushy habit as 
represented in the reduced figure in the plate. It flowered 
m April of the present year. 
Dzscr. A majestic herb, attaining ten feet in height, 
branched diffusely from the base upwards, viscidly glandular- 
pubescent; branches terete, ascending, leafy. Leaves ten 
to eighteen inches long, by four to six broad in the speci-

and principal nerves and reticulate nervules. Panicles

green ascending, lax-flowered, tubercled at the articulation 
of the pedicels ; bracts narrow, caducous; pedicels half to 
two-thirds inch long. Flowers inclined, one and a half 
inches long. Calyzx broadly terete, half inch long, smooth, 
ee: base rounded; lobes unequal, narrow, obtuse, 
shorter than the tube. Corolla slightly ineurved, pale 
“Dae and pubescent externally; tubular portion rather 
onger than the calyx lobes ; lobes ovate, obtuse, spreading,
