the axil of the sepals numerous: corolla yellow with broad 
obtuse lobes; tube 12 to 14 lines long a little swollen at the 
top: stamens inserted near the middle of the tube: disk pro- 
minent; style long; follicles 2, reflex, oblong and obtuse, 13 
to 2 inches long by 1 to rJ inches broad; seeds numerous, 
oblong, 4 to 5 lines long.—Near 7. granzazfora, but the fol- 
licles of this latter species are acuminate, the leaves ever- 
green, and the bracts and sepals different. Capt. Smith ob- 
serves of this plant: ''It is not. exactly a tree in habit. It 
occurred everywhere I went from the coast up to the slopes 
of the volcanoes at an elevation of 5,000". The natives call 
it cobal (varnish gum)." 7. grandiflora, as is known, was 
referred by Miers to S/emmadenia, but is retained by Mr. 
Hemsley in Zaéeruemontana. The difference between these 
two genera is sometimes a little difficult to determine. My 
species has certainly the salver-form corolla of 7aéernemon- 
tana. (J. N. Rose.)—Under the following numbers of the
