192 XXIX. RUTACE^. [Erio.temon. 



7. E. parvifolius (small-leaved), It Br. Herb.: Benth. Fl. Austr. i. 335. A 

 low, erect, compact, much-branched, glabrous shrub. Leaves crowded, linear- 

 cuneate, obtuse, 3 to 4 lines long, slightly glandular -crenate, flat, coriaceous, 

 without any conspicuous midrib. Flowers small, terminal, solitary, shortly 

 pedicellate, glabrous. Sepals small. Petals 2 to 2^ lines long. Filaments 

 flattened, eiliate ; anthers minutely apiculate. Cocci short, truncate, obscurely 

 beaked. Seeds minutely tuberculate. 



Hab.: Shoalwater Bay, R. Brown (Herb. R. Br.) 



5. PHEBALIUM, A. Juss. 



(One of the ancient names of the Myrtle.) 



Calyx small, 5-cleft or 5-toothed. Petals 5, valvate or laterally imbricate, but 

 always with valvate inflexed tips. Disk narrow or angular. Stamens 10, shorter 

 or longer than the petals ; filaments glabrous or rarely slightly eiliate, filiform or 

 rarely flat, subulate at the top ; anthers tipped with a small gland or not at all 

 apiculate. Carpels 5, rarely 4 or fewer, distinct from the base or nearly so, 

 usually produced into a short or long appendage above the cells ; styles inserted 

 below the middle and immediately united into one ; stigma small ; ovules 2 in 

 each cell, superposed. Cocci 2-valved, usually more or less beaked at the top or 

 the outer angle ; the endoearp cartilaginous and separating elastically. Seeds 

 usually solitary. — Shrubs, either glabrous or slightly stellate-pubescent or clothed 

 with scurfy scales, very rarely hirsute. Leaves alternate, simple, entire or 

 slightly toothed, the glands often large and prominent. Inflorescence axillary or 

 terminal, peduncles rarely 1-flowered, usually forming an umbel-like shqjrt 

 raceme, rarely reduced to a compact head. Flowers small, white or yellow, very 

 rarely and exceptionally 4-merous or 6-merous. 



Besides the Australian species, which are all endemic, the genus comprises one from New 

 Zealand, nearly allied to, but apparently distinct from, one of the Australian ones. F. v. 

 Mueller unites the genus with Erioatenion, but the asstivation of the corolla, besides the habit 

 and a number of smaller characters, appear to me sufficient to warrant the maintaining it as 

 distinct. Practically, the section Leionema may be at once distinguished from Eriostemon by 

 the strictly valvate corolla, and Phehalinm proper by the scurfy scales always present at least on 

 the flower and ovary. — Benth. 



Sect. I. Xieionema; F. v. M. — Glabrous or pubescent plants without scurfy scales. Petals 

 strictly valvate, glabrous. . 



Flowers terminal. Stamens usually exserted. 



Leaves obtuse, J to Jin., thinly coriaceous 1. P. elatius. 



Leaves small, obovate or orbicular, rigid but not thick, flat or concave 2. P. rotundi folium. 



Sect. 2. XSupliebaliuni. — Tlie whole plant or at least the inflorescence and calyx, and often 

 the petals aiul ovary, more or less covered with scurfy peltate scales, often fringed at the edge, those 

 of the ovary often closely imbricate in mie mass. Petals laterally imbricate or rarely almost 

 valvate in the bud, ivith inflexed valvate tips. 



Umbels terminal. 



Leaves linear-cuneate, truncate or emarginate 3. P. glandulosmn. 



Leaves oblong or linear, rounded or obtuse at the top, | to IJin. long . 4. P. squamulosum. 

 Leaves oblong, lanceolate or linear, obtuse or acute, from Jin. to 3, 4, or 



Sin. long, glabrous above, silvery underneath 5. P. Nottii. 



Umbels terminal and lateral, loose. Leaves oblong or lanceolate or linear, 

 1 to 2in. long or more. 

 Leaves silvery-white underneath. Petals -distinctly imbricate, not scaly 6. P. Billardieri. 



1. P. elatius (tall), Benth. Fl. Amtr. i. 840. A tall shrub, glabrous or the 

 branches very minutely pubescent, and usually tuberculate with prominent 

 glands. Leaves linear-cuneate or oblong, obtuse, \ to fin. long, entire or 

 crenulate, thinly Coriaceous, smooth and shining, narrowed into a very sliort 

 petiole. Peduncles 2 or more-flowered, terminal or in the uppermost axils, form-
