In Aspidop- Mlptage Madablota. terys, sessile petals are seen, styline branches with dilated stigmatiferous apex, fruit formed of membranous, scutiform, elongated samarse, and opposite leaves without glands or stipules. Triaspis also has leaves without glands, and membranous scutiform samarse; but the petals are fimbriate and unguiculate, and the Kg. 442. Eipe carpel. subulate styline branches are flexuous, stigmatiferous towards the apex. With the same style, Flabellaria has a valvate calyx with unequal divisions, sessile, narrow, elongated petals, often lanceolate, and the scutiform samarse bear a small dorsal wing. The petioles are glandular. In Juhelina, inhabitiag Guiana, the flowers are very nearly the same as in the preceding genera, but collected in. quadriflorous false umbels and provided with an involucre. Of the five sepals, four only bear a large medial gland below and without, and the styliae branches terminate m a stigmatiferous extremity dilated in the shape of a reversed foot. The fruit is formed of three samarse bearing five vertical dorsal wings irregularly cut and appearing to be each divided into three hollows. The medial alone is a true cell containing the seed. In Hiptage (fig, 442), each samara bears only three wings, two lateral and one dorsal. The calyx possesses only a single gland; it is large, elongated, alternate with two sepals, and descends on the apex of the pedicel to whic
