broad, on a petiole 3 or 4 lines in length. The primary peduncle 

 is 3 to 6 lines long, branching somewhat umbellately into from 

 three to six branches, which are again dichotomously, or some- 

 times umbellately subdivided into lengthened curving branchlets, 

 from 6 to 9 lines long, closely and pectinately beset with pedi- 

 cels, from which the articulated flowers have fallen off, all being 

 quite glabrous and of an ochreous colour. The calyx is small, 

 cupshaped, minutely 5-toothed; the petals adhere by their mar- 

 gins below in a tubular form, the summits being quite free; 

 the stamens are the length of the petals, but the long ciliated 

 crests are far exserted ; the filaments are thick and fleshy, having 

 their margins and apices charged with very long clavate white 

 hairs ; the upper part of the inner keel interposes between the 

 lower part of the two lobes of the anthers, which are oval, deeply 

 separated at their base, the lobes being attached dorsally at their 

 junction to the apical point of the filament ; they are pollini- 

 ferous, the granules of pollen being sharplj^ 3-angular : the ova- 

 rium is distinctly ovuligerous.

This species is remarkable for its very long narrow leaves, 

 which are attenuated at their apex into a lengthened linear ex- 

 tension ; they are of a pale colour above, of a glaucous yellowish 

 hue below, about 6 inches long, including the linear apical ex- 

 tension of an inch in length, and ^ of an inch broad, upon a 

 slender petiole 3 or 4 lines in length. The inflorescence seldom 

 exceeds 4 lines in length, several flowers about 2 lines long 

 being almost fasciculated on an axillary peduncle of 2 lines in 

 length, all quite glabrous : the calyx is small, cupshaped and 

 5-toothed ; petals 4, linear ; stamens 4, with very fleshy filaments 

 nearly the length of the petals, furnished on their margins and 

 apex with a dense fringe of long clubshaped hairs ; the two anther 

 lobes are each 2-celled, sterile, and filled with grumous matter ; 

 the ovarium is smooth, cylindrical, \ ov ^ the length of the 

 stamens, sterile, and terminated by a hollow, tubular, conical 

 style, divided at its apex into four acute erect teeth.
