lesser number of hairs, the veins show up more clearly on the perianth of 
Caladenia latifolia. The labellum in each is three-lobed, but in the 
variety, the middle lobe is shorter than that of the type, and its margin 
is.distinetly crenate. The flowers are pale yellow instead of pink or 
white, as in the type. — West Australia, Lowden, Preston River.

58. Hakea sulcata R. Br. var. intermedia Ewart and White, |. c., 
p. 293. (Proteaceae.) — This variety seems to be nearest to Hakea sul- 
cata var. scoparia, from which it differs, however, in being of a more 
slender type, in having less suleate leaves, and in possessing a pro- 
minent ridge round the stigmatic cone. — In this last respect, it re- 
sembles the.typical H. sulcata from which, however, it differs in the 
following characters: — 1. The leaves are much longer, and ore not so 
prominently sulcate. — 2. The pedicels usually slightly exceed 1 line in 
length. — 3. The hypogynous gland is much longer and more conspi- 
cuous. — West Australia, Cowcowing, Max Koch, 1904, no. 1056. 
54. Linum albidum Ewart and White, |. c., p. 294. „Rodway Flax.“ 
PI. LIV, fig. 1, 2. 4. — A glabrous herb from about 6 inches to 1,5 feet 
high. Stems slender, upright, and rather ribbed, with few basal leaves. 
Leaves 2 lines to half-an-inch length, alternate, lanceolate, pointed, ex- 
stipulate, sessile, but slightly ensheathing and narrowed at the base. — 
Inflorescence as in Linum marginale, forming a loose irregular, terminal 
corymb. Sepals 2—3 lines long, ovate, lanceolate, acuminate, with a 
narrow scarious margin as in L. marginale, but they differ from this 
species in not possessing a very prominent midrib, the sepals have a 
more rugose surface, and a broader membranous base. — Petals white, 
about twice as long as the sepals. — Stamens 5 united into a basal 
ring, the 5 staminodia being represented by minute points attached to 
the ring, alternating with the stamens and opposite the petals. Ovary 
similar to that of the L. marginale, but a little more convex at the top. 
Style about half-a-line in length, and the branches only united about 
1/, of their length, the free parts radiating, and with a slightly pappu- 
lose terminal stigma on each. Fruit a superior capsule, dividing into 5 
coeci, with 2 small flat seeds in each compartment. The plant does 
not appear to agree with any non-Australian Linums. It was found in 
a district not invaded by aliens, and was sparingly distributed over an 
area of some miles. There seems to be no doubt that it represents an 
undescribed species of very restricted range, and is of especial interest 
as forming an addition to a genus represented in Australia by a single 
endemic species. — Tasmania, Western mountains, 4000 feet altitude, 
L. Rodway. 
Sarga Ewart, nov. gen. — Spikelets one-flowered on filiform 
pedicels, in groups of 3. — One hermaphrodite spikelet being situated 
below 2 male spikelets, the rachis of each group of 3 spikelets being 
articulated below the glumes of the hermaphrodite spikelet; the part of 
the rachis above the artieulation forming a sharp-pointed stipe to the
