*C. caldeirarum, var. amplifolia n. var. 
San Miguel, (14, 15,— in the vicinity of the Furnas, 
especially abundant and well developed in the large 
grotto beside Lagoa das Furnas, a short distance above 
the hot springs; Carreiro, at Candellaria). 
At length afoot high, slender and lax, spreading by a rather stout 
root-stock, with sparse white hairs, especially about the bases of the 
petioles: flowers larger: foliage as in C. amara: capsules slender, 
remote, very divergent on capillary pedicels less than half their 
length, not surpassing the floriferous end of the stem.— Plate 16. 
An interesting form with rather larger flowers than the type and 
leaves most closely resembling those of C. amara, but the fruit and 
habit of theformer. From C. hirsuta it differs in its larger flowers, 
and from C. sylvatica in its few very spreading capsules.— But the 
figure of C. sylvatica in Rchb. 2. pl. 26 might almost pass for some 
forms of C. caldeirarum.
