Croton (§ Decarinium) Magdalene, sp. nov. A branch- 

 ing shrub 1 meter high; branches terete, densely covered 

 with a matted, partly stellate, tomentum. Leaves large, 

 petiolate, cordate, acute, reticulately veined and stellate pu- 

 bescent on the parenchyma; veins densely woolly beneath; 

 stipules represented by a single axillary bud-like gland. 

 Inflorescence terminal, spicate, sessile, the female in a whorl 

 at the base, the male scattered along the rhachis above; 

 rhachis elongated, quadrangular, twisted, furnishing a short 

 bract to the base of each floral pedicel. Female calyx un- 

 equally 5 parted, the lobes ovate acute; petals wanting; 

 ovary densely tomentose; styles dichotomously divided al- 

 most to the very base, the lobes linear elongated with a 

 tooth-like process at about the middle — rudiment of another 

 bifurcation. Male calyx 5 parted, the lobes deltoid, equal; 

 petals lanceo-spatulate alternate with and longer than the 

 sepals, hairy at the base; stamens 15 (more or less), fila- 

 ments hairy at the base. Capsules densely tomentose and 

 stellate pubescent below; seeds shining, smooth, with a few 

 slight, smooth longitudinal ridges upon the dorsum, and a 

 short, spinous process at the summit behind the sarcous 

 caruncle. 



Branches 1-3J dm. long; leaves 10 cm. long, 8 cm. broad, 

 and smaller, perfectly cordate; petioles about one-third the 

 length of the blade: spikes 5-9 cm. long: capsules 14 

 mm. in diameter; seeds 7 mm. long, 5 mm. broad. — Magda-
