. The natural history of plants. Botany. Fl9. Mower. Pig. 225. Flower (f) Fig. 226. Open fruit. Fio. 223. Flower before libera- tion of style. gamous flowers, two anatropous ovules, and opposite leaves. Helicia, though, very close to Xylomelum, differs in its fleshy indehiscent fruit. Lambertia has regular flowers formed like those of certain Grevilleas; but it is distinguished by its two ovules being nearly orthotropous descending, the micropyle still looking downwards; and we may remark that this is a constant character in the order, the causes of which we have investigated elsewhere.' The micropyle is always inferior, whether the ovules are ascending and more or less completely anatropous, or orthotropous or nearly so, and consequently descend- ing ; the base of the ovary is surrounded by four leaves, alternate with the perianth-leaves. Boupala approaches Lambertia by its quite orthotropous ovule; its fruit is a* follicle opening longitudinally. Andripetalum has the flowers of Boupala with a slightly fleshy drupaceous indehiscent fruit. Guevina has the same orthotropous ovules, and a nearly dry indehiscent fruit; but the flower is slightly irregular, the perianth being inserted obliquely on the receptacle, with the two anterior leaves attached lower down than the posterior pair.
