XC. MYOPORINEAE.
[Pholidia.

P. Delisserii have only 1 ovule in each of the ovary-cells as in the majority of Myopora. From Eremophila, Pholidia differs in the more regular corolla, the calyx-segments never enlarged after flowering, the stamens not exserted, the ovules never superposed in each half cell, and the fruit not separating into 1 seeded nuts as in the Section Eremocosmos, nor so succulent as in Stenochilus, but none of the latter characters are constant through all the species of Eremophila, and the fruits of some species are as yet unknown. The distinction between Pholidia and Eremophila is not, therefore, more definite than that between Pholidia and Myoporum.

Leaves mostly opposite, hoary or white, almost scaly, usually recurved at the end. Flowers sessile or nearly so.

Leaves narrow-linear, ¾ to l in. long

1. P. Dalyana.

Leaves narrow-linear, rarely above ⅛ in. long

2. P. scoparia.

Leaves obovate or oblong, 3 to 4 lines long

3. P. Delisserii.

Leaves alternate, obovate, or ovate, 3 to 5 lines long. Flowers sessile or nearly so.

Leaves very thick, complicated and recurved, glaucous or hoary

4. P. crassifolia.

Leaves rather thick, white on both sides, resinous

5. P. resinosa.

Leaves rather thin, green, often toothed.

Leaves obovate or cuneate, acute, mostly toothed. Ovules 2 in each cell

6. P. Behriana.

Leaves ovate or elliptical-oblong, entire. Ovules 2 in each cell

7. P. Woollsiana.

Leaves ovate, entire or toothed. Ovules 1 in each cell

8. P. brevifolia.

Leaves alternate, entire, crowded or imbricate, ½ to 1 in. long.

Flowers sessile or nearly so.

Leaves oval or oblong, white-tomentose. Ovary glabrous

9. P. imbricata.

Leaves linear, acute, glabrous. Ovary woolly

10. P. densifolia.

Leaves alternate, narrow or small, not crowded. Flowers sessile or nearly so.

Leaves small, erect, with a few large tubercles. Fruit compressed, obtuse, not exceeding the calyx

11. P. gibbifolia.

Leaves linear, entire. Branches divaricate, often spinescent. Fruit beaked

12. P. divaricata.

Leaves linear, not gibbous, erect. Branches erect, hoary-pubescent or nearly glabrous. Leaves 2 to 4 lines long

13. P. microtheca.

Very viscid-pubescent. Leaves 1 in. long

14. P. adenotricha.

Leaves narrow-lanceolate, above 1 in. long. Pedicels about 4 in. long

15. P. santalina.


1 P. Dalyana, F. Muell. Very closely allied to P. scoparia, and perhaps a variety only, differing; in the leaves longer and more slender, usually ¾ to 1 in. long, the corolla-tube not so much contracted at the base, and the ovary densely villous instead of being' scaly only. — Eremophila Dalyana, F. Muell. Fragm. v. 22.

S. Australia. Between Cooper's Creek and Stoke's Range, Howitt's Expedition. There is but a single specimen (Herh. F. Muell.), and I could only examine one ovary, which was 2-celled as in P. scoparia, but one ovule of each cell was very small and probably abortive.

2. P. scoparia, R. Br. Prod. 517. An erect shrub, hoary or almost silvery, with a close more or less scaly indumentum, the branches rigid, but not thick, -with prominent angles decurrent from the leaves. Leaves mostly opposite or nearly so, narrow-linear with hooked points, rather thick, keeled underneath, channelled above, rarely exceeding ½ in. in length. Flowers of a pale violet blue, solitary on short axillary pedicels, without bracts. Calyx l¼ to l½ line long,
