Nubian, and a twelfth to the forms of the Mediterranean 
region. Amongst these forms common to the temperate 
Atlantic Islands the Campanulacee hold a most conspicuous 
place, as instanced by the beautiful Campanula Vidalii 
(Plate 4748) being peculiar to one spot in the Azores 
Islands; Musschia aurea (Plate 6556), and M. Wollastoni 
(Plate 5606), being both confined to Madeira; and Canarina 
Campanula (Plate 444) being restricted to the Canary 
Islands. Nor is this continuity of vegetable affinities con- 
fined to the Campanulacee; it extends to Composite, 
Crucifere, and other conspicuous Orders. 
Campanula Jacobea is arather common Cape deVerd plant, 
_ inhabiting 8. Nicolas, Brava, 8. Antonio, S. Vincent, and 8. 
Jago, in which last I gathered it (in 1839) on arid rocks about 
2000 feet above the sea-level. It was introduced into 
cultivation by our valued correspondent, Max Leichtlin, who 
communicated seeds to Kew, which produced (in a cold 
frame) the flowering specimen here figured in March of this 
year. The flowers in a native state vary in colour from 
pale greenish-yellow to a deep blue; those that were pro- 
duced at Kew were of the colour represented in the flower 
at the side of the Plate. 
Dusor. An undershrub, two to three feet high ; stem 
below woody, hollow, gnarled, brittle; branches green, 
angular, rather soft, leafy ; all parts, except the corolla, 
hispid with white spreading hairs. Leaves one and a half 
to two and a half inches long, sessile or subsessile, oblong 
ovate or obovate-oblong, obtuse or subacute, narrowed at 
the base; upper cordate, half-amplexicaul. Flowers axillary 
on curved pedicels two to three inches long, nodding or 
drooping. Calya-tube very small; segments one-half to 
two-thirds of an inch long, erect, narrowly lanceolate, 
margins at the base reflexed, sinus sometimes produced 
backward into an auricle. Corolla campanulate, one to one
