232 PHANEROGAMIA. 



almost orbicular in outline, 9 or 10 lines in diameter, slightly grooved 

 on the back, especially next the base, where they are sometimes a 

 little emarginate, the surface even or slightly roughened. Seeds very 

 numerous, closely packed in two rows in each cell, vertically more or 

 less compressed, 2 to 2h lines in diameter; the purple or brownish 

 testa rugose-roughened (Plate 19, Fig. 13), usually dull. — Of the 

 various forms of this species which occur in the collection, one, the 

 var. /?., has the leaves mostly acuminate, 5 or 6 inches in length and 

 proportionally narrow {oolong-lanceolate), the lower surface, as well as 

 the branchlets, bracts, &c, clothed, even at maturity, with a dense 

 brownish-yellow tomentum. In the typical forms the down is seldom 

 so yellow or so persistent. The specimens from Mouna Loa and from 

 the district of Puna have smaller leaves, of very thick texture, and 

 their young capsules are densely tomentose. Another variety, if such 

 it be, the var. y., has usually smaller leaves, only Ih to 3 inches in 

 length, much crowded at the summit of the branches, and entirely 

 glabrous, even when young; but the inflorescence and calyx are more 

 or less tomentose-pubescent. It must be left for a more complete 

 suite of specimens, in fruit as well as in flower, to determine the true 

 limits of this apparently polymorphous species.

"Tree 20 feet high, with odoriferous flowers." Branches very stout, 

 leafy, woolly when young. Leaves very thick and coriaceous, alternate, 

 but crowded on the branches, sometimes imperfectly whorled, obovate, 

 or obovate-oblong, obtuse, or often with a short acumination, tapering 

 at the base into a short petiole, the nascent ones woolly both sides, 

 when full-grown very glabrous above and somewhat shining, densely
