poor herbage, the potato grows in abundance. It was spread 
not less plentifully in the island of San Lorenzo, near Callao. In 
these two localities it may perhaps have been brought by the 
hand of man; but it does not seem likely." 
Since I began this paper M. André has kindly sent me for 
examination the beautiful series of dried specimens which he 
brought home. 
The Quindio plant is evidently identical with S. Otites, Dunal 
in DC. Prodr. xiii. 1639. This is marked by its slender sarmen- 
tose glabrous stems, petiole longer than in tuberosum, nine thin 
oblong acute subglabrous leaflets 1-2 in. long, with sometimes 
but not always two small ones below the nine, but none inter- 
spersed amongst the large ones, a subglabrous calyx with deltoid 
segments much shorter than the tube, a small whitish corolla 
with deltoid lobes, and by its ovoid pointed fruit. The tubers, 
which were previously unknown, are described by M. André as 
being grey, oblong, 2-4 centimetres long, 1-1} cent. broad, with 
a bitter taste. If not a distinct species, it must be considered a 
well-marked variety of S. tuberosum. 
The plant from La Union is evidently a distinct species. It 
appears to be about midway between S. tuberosum and 5. terna- 
tum of Ruiz and Pavon. M. André did not find any tubers ; 
but thinks it quite possible that they may exist. As I cannot 
identify it with any species already known, I have ventured to 
characterize it as a novelty, excluding it for the present from the 
category of tuber-bearing types. 
SOLANUM ANDREANUM, n. sp.: herbaceum, subglabrum, tube- 
ribus nullis vel ignotis, caule flexuoso, foliis atroviridibus pseudo- 
stipulatis, petiolo producto, foliolis magnis oblongis acutis 3-5 
basalibus parvis 1-2, accessoriis interjectis nullis, cymis laxis 
multifloris pedunculatis, pedicellis subglabris supra medium 
articulatis, calycis subglabri segmentis deltoideis, corolle vio- 
lace: segmentis deltoideis, fructu ignoto. 
Petiole above an ineh long when the small basal leaflets are 
present; above 2 in. when they are absent. End-leaflets 22-3 in. 
long, much narrowed at the base. Corolla an inch in diameter. 
Anthers 4 in. long, with very short filaments. Style only pro- 
truded a little beyond the anthers in the flower. 
The Lima plant is a form of S. tuberosum, as here understood, 
to whieh also must be referred specimens gathered by M. André 
at Pasca, in New Granada, at an altitude of 2500 metres above
