Edwards's Botanical Register/Appendix to the first twenty-three volumes/A sketch of the vegetation of the Swan River Colony/Pittosporaceae
Pittosporaceæ.
The forms of this order found in the Colony are, with the exception of a Plttosporum of which I have seen fragments, almost peculiar to the West Coast. Both Sollya heterophylla and S. linearis are found; the latter is a new species, with very narrow undivided leaves, and flowers of the brightest blue; it has recently been introduced by Mr.
Mangles. There are at least three species of Campylanthera or Pronaya, twining shrubs, with loose cymes of very pretty flowers; of these, Campylanthera (Pronaya) elegans has close clusters of lilac and white blossoms, and has been introduced by Baron Hugel, in whose Archiv it is figured at t.6; C. Frazeri has very narrow leaves, and rather loose violet cymes on long peduncles; and the third, which is perhaps not different from the Pronaya speciosa, Endl., is much the finest of the genus, having very compound smooth cymes, fully five inches in diameter; of this plant the flowers are large and white; I have in addition to these what may be a mere variety of the last, with smaller flowers and a hairy inflorescence. In Hugel's Enumeration is mentioned a Marianthus candidus, found among rocks at the Swan, with white flowers arranged in long-stalked repeatedly di- or trichotomous terminal cymes; this plant I have not seen, but in Mr. Toward's collection there is a plant, apparently belonging to the same genus, with branching, half twining, smooth and deep brown branches, oblong leaves, some of which are serrated, and few flowered terminal cymes of white flowers striped with purple; this, which may be named Marianthus pictus,93 would form a neat and pretty twiner.
(93) Marianthus pictus; ramis subvolubilibus resinoso-rugosis nitidis, follis petiolatis ovalibus glaberrimis subtùs pallidis nunc inæqualiter serratis, cymis paucifloris sessilibus.—Flores irregulares, petalis ascendentibus spathulatis obtusis. Stamina 5, inæqualia, declinata; antheris ovatis rectis, basifixis, long, dehiscentibus. Ovarium declinatum, 2-loculare, ovulis 00 uniseriatis, stylo continuo, stigmate simplici.
