THE GENUS NOTOTRICHE. 235 
(8) N. Jamesonii.—From the hairy forms (the true N. phyllanthos) one passes to 
another type, which I have named N. Jamesonii, a very distinct plant in certain 
particulars, but very possibly linked with N. phyllanthos by intermediate forms. The 
types of this species are two specimens of Jameson's at Kew (no. 154) and the specimen 
labelled * Chimborazo, 15,000 ft. (Aug. 1829)." A specimen from Chimborazo (14,359 
feet) at the British Museum, collected by Whymper *, and Meyer's no. 151 B, from the 
Paramos of Chimborazo at 4200-4500 m. alt., are also identical with the Kew species. 
The chief distinguishing characters of this species are the long petioles, which, like the 
laminze, are covered with a velvety pubescence on both sides; the velvety calyx; and 
the corolla, which is larger than that of N. phyllanthos, and differs markedly from that 
of the two preceding species in the possession of a corolla-tube 3-4 mm. in length. 
The stamens, however, are arranged in a cylindrical head and the carpels have shorter 
beaks. It is also of interest to note that Chimborazo appears to be the home of this 
species, and it may be that it is due to its isolation on this mountain that this particular 
specific type is being developed. 
(4) N. Hartwegii.—To the forms already mentioned must be added Hartweg’s no. 918, 
which was determined by Bentham to be Sida pAyllanthos, Cav., a determination which 
was accepted by Weddell. Much of the confusion connected with these northern forms 
is due to this erroneous identification. This plant, with which a specimen at Kew 
collected by Jameson also agrees, is very distinct from all the others, and very easily 
distinguished as a definite and well-marked new species, which I have named JY. Hart- 
wegit. The habit of growth, nature of the tomentum, and the shape and lobation of 
the lamina, &c., mark it off clearly from N. phyllanthos, which is perhaps its nearest ally. 
It is possible that a definite affinity exists between these northern species and 
XN. Macleanii (Pl. 99. fig. 13), N. Matthewsii (fig. 11), N. stenopetala (fig. 17), and 
N. epileuca. 
In the following diagram an attempt is made to represent the possible alliances of 
the four species under discussion :—
