A long known, but rare and curious greenhouse plant, 
remarkable for the dark violet-blue hue of the flowers, which, 
however, in native specimens, vary to lilac and pink. It has 
a wide range in Western Australia, from King George's 
Sound to Champion Bay, and occurs under three principal 
forms :—1. With broad leaves, very silky beneath, with waved 
margins, and usually solitary flowers ; 2. With elliptic-oblong 
leaves, only slightly hairy beneath, hardly waved margins, 
and solitary flowers; this is the B. melanopetalum of Mueller, 
and that figured here; 3. With linear leaves glabrous 
beneath having involute margins and racemose flowers. Of 
these the first is the common Swan-river form, and is also 
found at Champion Bay; the second comes from the Tone 
and Don rivers, and the third from the Tone, Gordon, and 
Blackwood rivers. 
Brachysema undulatum is a hard-wooded greenhouse shrub, 
requiring the same treatment as Chorozemas, &c. It was 
AuGusT Ist, 1874.
