much longer and less distinctly clustered leaves, larger flowers, cili- 

 ate sepals, and more numerous stamens. It is probably the tallest 

 Hibbertia in New South Wales, unless H. saligna R.Br., occasion- 

 ally attains a larger size. 



Hibbertia Kochii, n.sp. 



Lowden, Western Australia (Max Koch; October, 1909). 



Frutex erectus, 20-30 cm. altus, pilosus. Folia lineari-lanceo- 

 lata, 12-15 mm. longa et 2 mm. lata, obtusa, margine revoluta, sub- 

 tus plana pallidaque. Flores solitarii, pedunculis gracilibus circiter 

 30 cm. longis. Bracteola sub flore, sepalis brevior. Sepala obtusa, 

 circiter 4 mm. longa, interiora latiora hyalino-marginata, pilosa 

 aeque quam pedunculis, foliis et ramulis. Petala flava, biloba, cir- 

 citer 8 mm. longa. Stamina 10, unilateralia. Staminodia 3, unila- 

 teralia. Carpella 2, biovulata, villosa. 



A small, much-branched, erect shrub barely 6 inches high in some 

 specimens, and apparently always below one foot high, the young 

 branches, leaves, peduncles and calyces generally loosely covered 

 with rather long spreading hairs. Leaves linear or linear-lanceo- 

 late, 6 or 7 lines long, and about one line broad in the upper half, 

 obtuse or with a very small recurved point, the margins revolute 

 but leaving the smooth, somewhat paler under surf ace open. 

 Peduncles one-flowered, slender, leaf -opposed on the upper part of 

 the stem, or terminal on short branches, 1 to 1 J inches long, with a 

 small, leaf-like bracteole close under the calyx, shorter than the 

 sepals. Outer sepals narrow-ovate, the inner ones broader, and 

 with scarious margins, about 2 lines long, all obtuse, the spreading 

 hairs on the midrib and margins. Petals yellow, 2-lobed, about 

 4 lines long. Stamens 10 or rarely more, all on one side of the car- 

 pels in a dense cluster, with three short, narrow staminodia on 

 each side of the fertile stamens and close to them. Carpels 2, vil- 

 lous, 2-ovulate. [Seeds not seen.] 



The new Hibbertia belongs to the section Hemipleurandra, and 

 is very closely allied to H. hypericoides Benth., but differs from it 

 essentially in the indumentum. The stellate hairs of H. hyperi- 

 coides are entirely absent in H. Kochii, which has long spreading
