Particles terminal or axillary, 5-40 cm. long, ferruginous-tomentose. Flowers with the hypanthium 5-8 mm. long, carnose, densely puberulent, the carinal tooth 1.5-2 mm. long, rounded, the vexillar teeth broader and less rounded; vexillum orbicular, about 8.5 mm. long; wing petals obliquely oblong, about 7 mm. long, rounded at the apex, oblique at the base, ciliate at the claw; carinal petals reniform, about 6 mm. long, rounded at the apex, the claw obviously ec- centric, ciliate; staminal sheath about 3 mm. long, ciliate, the filaments up to 1 mm. long; ovary obviously stipitate, pilose, the style about 0.6 mm. long.

Note
|
The flowers of both M. cirrhiferum and M. arborescens are described as laven- der. While M. merrillii, unlike M. arborescens, has stiff hairs on the seminiferous area of the fruit, it is so similar to M. cirrhiferum in other respects that I have not hesitated to reduce it to synonomy.
