Long. sect, of flower (^). complete types, that is those with as many ovarian cells as petals, it may be said to represent the woody Aralias with valvate corolla and the Scheffleras with articulate floral pedicels. Such is often the case with those named Psevdopanax and Cheirodendron. They have a short calyx, five or six valvate petals, as many stamens and ovarian cells. The size and form of their styles are very variable, and that often in the same species according as the gynsecium may assume a greater or less development. The stylary divisions are either very small, obtuse, erect, indistinct, or long- subulate, recurved, and between these extremes there may be every possible intermediate gradation. In one species also, the number of ovarian cells may descend to three or two. It is ordina- rily so in Notlwpanax (fig. 206, 207), which'cannot be generally separated from Polyscias, particularly from those numerous in the Mkscarene isles which have as many as ten or fifteen carpels; the number of petals and' stamens may at the same time be augmented. In certain Polyscias and in Eupteron there are only five petals and the same number of superposed ovarian cells. In P. Boivini, a species from Mada- gascar, of which a genus Sciadopanax has been formed-, the ovary is bilocu- lar and the styles are united in a conical mass by two Small stigmatife- rous lobes. The seeds have four large vertical furrows. In P. Maralia, from the same country, the styles, five in number, are reflexed like those of most Polyscias, and the seed is fur- rowed like that of Sciadopanax; it has been said to be ruminate, but this is certainly not constant. In Madagascar there is a Panax in which one cell in the ovary and fruit is aborted, and of which the genuS Guphocarpus has been made. Panax {Pohjscias) pinnata..
