(Page 68.) Mueller considers that his Boronia dentigera, Trans. Viet, Instit. 1855, p. 32, men- 
tioned under B. variabilis, is a very distinct species, having rough seeds. 
(Page 69.) Discaria australis occurs in one spot only on Brown's River, south of Hobarton, the 
most southerly habitat I am acquainted with (O/dfield).

In the generic character, line 2, for longioribus read brevioribus; and in the English description of the genus,

When I drew up the characters of the species of this genus, I had not seen the elaborate monograph of 
Schuckhardt, published in the Linnea, 1853, the results of which are so different from mine that I have again 
attempted to settle the limits of the species of this puzzling genus. 
1. Stackhousia monogyna, Lab., and S. obtusa, Lindl. 
S. monogyna, according to Labillarditre, should have one bract and two minute deciduous lateral ones, and his 
figure accords well with Lindley’s t. 1916 in most respects. Lindley further describes the bracts as very short, 
shorter than the calyx, and membranaceous, but figures those of the lower flowers as longer than the calyx. The 
S. obtusa he distinguishes by having the bracts longer than the calyx, and the spike shorter, and cylindrical. None 
of these characters are constant in Gunn's specimens ; and in my own, gathered near Hobarton, I find the bract 
varying from shorter than the calyx to half as long as the corolla. Schuckhardt gives no distinguishing characters, 
but describes the corolla of 5. monogyna as flavescent (which Lindley figures white), and of 5. obtusa as yellow 
(lutea). Archer considers them the same, and Gunn also observes that he found connecting specimens between 
S. obtusa and monogyna. The lateral bracts are evanescent in most of the Tasmanian specimens. 
2. Stackhousia Gunnii, Hook. fil., is considered by Archer to be a variety of 8. monogyna, and no 
doubt rightly so. 
3. Stackhousia maculata, Sieb. 246. 
Schuckhardt remarks that no such species exists in the Herbarium Rudolphianun, where all Sieber’s plants are 
without exception to be found. Sieber's plant is, however (probably erroneously), named 8. maculata in the Hookerian 
Herbarium, Fl. Nov. Holl, n. 246, and it is no doubt S. spathulata, Sieb., of Rudolph. Herb. (Schuckhardt, 
p. 20), S. maritima, Muell. MSS., S. cuneata, A. Cunn., Tripterococcus spathulatus, Mueller. This appears to be a 
maritime species. 
4. Stackhousia flava, Hook. fil. 
5. Stackhousia pulvinaris (Mueller, Fragm. Phyt.) ; parvula, intricatim ramosa ; foliis lineari-oblongis 
spathulatisve obtusis, floribus solitariis ramulos terminantibus, stylo brevissimo profunde 3—4-fido. 
Haz. Western Mountains, in moist places, Archer. 
DisrRrB. Australian Alps, Mueller. 
A very singular little speeies, scarcely 9 inches high, very different in habit and appearance HO any of its 
congeners. Mueller observes that it forms a carpet on the summits of the Australian Alps, speckled with fragrant, 
starry flowers.—S/ems much branched, slender, tufted and interwoven together. Leaves + inch long, glabrous, 
g, bright-green. Flowers solitary, terminal, scarcely rising above the leaves, 
rather fleshy, linear-spathulate or oblong i ; 
yellow. Stamens nearly equal in Archer's specimens, two shorter than the others in Mueller’s. Anthers glabrous. 
Style very short, cleft almost to the base. 
Stackhousia Gunnii, Schlecht. in Linnea, xx. 642, founded on Lindley’s figures of S. monogyna, 
appears to have no characters at all. Schuckhardt quotes it (altering the name to Gunniana), but does
