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.
Compositæ, or Asteraceæ.
The species of this order are numerous, and in some cases beautiful; a few of them are curious, but the greater part are neither the one nor the other. Gigantic thistles, eleven feet high, are mentioned by Frazer, but nothing corresponding to such plants has been seen by me. He also speaks of the barren sandy cliffs being in many places snow-white with the flowers of a Gnaphalium with procumbent stems, which is probably the Helichrysam Cotula, Benth. a genus of which there are many species; H. macranthum and bicolor, which are the handsomest, being already in cultivation. Nearly allied to these is Morna, a beautiful genus,
(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.
