outer smallest. Petals 5, just like the inner sepals in shape 
and vestiture, but with a densely pilose emarginate scale 
at the claw. Disk cup-shaped, irregularly lobed, enclosing 
the stamens and ovary. Stamens 20-24, inserted inside 
the disk, glabrous; filaments short, filiform: anthers mi- 
nute, oblong. Ovary sessile, densely pilose, 2-celled, with 
a single ovule in each cell from the axis below the mid- 
dle; style short, simple, pilose; stigma capitate. Fruit 
a 2-lobed velvety samara, with a broad wing. Seed glo- 
bose, black. Endemic and monotypic.”’ 
Hornea mauritiana Baker. |.c. p. 59. 
‘*A shrub or tree, with branchlets clothed with brown- 
ish silky hairs. Leaves short-petioled, equally pinnate; 
leaflets 4, sessile, oblong, obtuse, glabrous, coriaceous, 
venulose, 2—4 in. long, oblique at the base. Flowers in 
axillary and terminal panicles with silky ascending 
branches; pedicels very short. Petals and inner sepals 4 
in. long. Lobes of samara rhomboid, erecto-patent, an 
inch long, above 4 in. broad, brown-velvety, rigidly cori- 
aceous, the wing as broad as the cell. Thouinia? mauri- 
tiana, Bojer, Hort. Maur. 1837. 56 (name only).”’ 
It should be noted that Vhowinia (?) mauritiana 
Bojer has no standing because Bojer’s work was merely 
an enumeration of species, not accompanied by descrip- 
tions. The monotypic genus Hornea is taxonomically 
closely allied to Thouinia, but has been considered dis- 
tinct since the publication of Baker’s Flora.

‘*Plants rootless and leafless. Stems arising from pro- 
tocorm-like rhizomes, dichotomously branched. Sporan- 
gia terminal on ultimate branches, with a sterile colum- 
ella projecting from the base into the sporangial cavity, 
and cuticularized spores developed in tetrads. ”’
