| Calceolaria was raised from seed purchased in 1910 from 
r. J. D. Husbands, Limavida, Chile. It is one of the species 
rene ss to that a and has been collected by Mr. Elwes as far 
south as the Baiios de Chillan in Nuble at 5000-6000 feet above 
sea level, and by Prof. Philippi as far north as the province of 
Coquimbo. The plant bears a striking resemblance when not in 
flower to a Stachys or a Gnaphalium with its white woolly leaves. 
The flowers are borne in elongated lax corymbose inflorescences, 
and are pale violet or rose-coloured with a scent of violets. 
Rubber-yielding Plants from Peru—Mr. W. Fox, on a recent 
journey in the territory between the rivers Putumayo and Caqueta, 
collected five rubber-yielding plants, about which he has furnished 
the following particulars :—Hevea Foxii, Huber, is by far the most 
common and the best rubber-yielding species, and is the source of 
the Para rubber of commerce from this region. This species bears 
the vernacular name of I[turi or Iserai, but these names also eke? 
to be applied to another species of Hevea, allied to H. lutea. Of 
the rubber exported from this region 75 per cent. is dosed from 
- Hevea Foxit, and these trees are the only ones which are properly 
tapped. All the other rubber plants are cut down for the extraction 
of their latex 
Hevea is tapped by incisions made with a machete, and the 
latex is allowed to run down the tree to the ground, where it 
ulates. ‘The rubber is recovered in strips, which are taken to 
a stream and washed, and it is then rolled into rabos or tails, in 
which form it arrives in London. This crude method is due to the 
wide area over which the trees are scattered. 
Micrandra minor, Benth., bearing the vernacular names Huemega 
or Wakati Ewickeri, was found fairly evenly distributed, but was 
becoming scarce owing to the destructive methods of working. The 
latex of this tree is mixed with that of the Hevea, and is also 
used for wrapping the rabos or tails. 
A species of Castilloa, probably. C. elastica, though somewhat 
different from the type, was also collected, but as leafy specimens 
only ; it bears the name Caucho negro or cone. It is only 
found in ee near the Caqueti and Putumayo rivers. The 
case with the other trees. 
Another tree yielding rubber is the Minyadotana, a new species 
o Zschokkea described in K.B. 1912, p. 38, under the name 
Z. Foxii, Stapf. The tree is not very widely spread, and is 
becoming scarce owing to the methods of working. The latex is 
used for mixing with that of the Castilloa and the Hevea 
Lastly, a gutta-yielding plant was found which is ; probably 
Sideroxylon cyrtobotryum, Mart. This plant, which is known by the 
native name Arorate, is rare and was met with only at Oriente, 
near the Igara —— and the yield is therefore a negligible 
quantity.
