1. F. Willmottii (after Dr. J. Willmott), b . v. M. Austr. Journ. of Phann., 
April 1887. A tree about 80ft. high. Branchlets robust, the leaves crowded 
towards the summits, pinnate, mostly 5 or sometimes 8-foliolate ; petioles 
slender, about tin. long. Stipules about {-in. long, rather narrow, adnate except 
summit ; petioles slender, rather elongated to 1-Jin. long. Leaflets in distant 
pairs, dark-green on both sides, chartaeeous to lin. long, lin. wide, elliptic- 
lanceolate, acuminate, entire, somewhat crisped, shining, blunt at the base, 
subtle-veined. Umbels almost cymosely arranged, seldom exceeding lin. in 
length, the whole inflorescence much surpassed by the nearest leaves. Flowers 
not seen. Pedicels somewhat longer than the fruiting-calyx ; limb of the latter 
undulated and bluntly 5-toothed. Styles very short, undivided ; disk depressed. 
Fruit campanulate, semi-ovate, 5-angled, 5-seeded, not distinctly jointed on the 
pedicel, about {-in. long, their longitudinal angles blunt; pericarp somewhat 
succulent ; each endoearp pale-brownish, dimidiate-ovate, about {in. long, 
narrowed at the inner angle, bluntly rounded at the back, somewhat wrinkled 
at the sides; testa membranous, not intruding. Albumen equable, but slightly 
glandular: embryo minute. — F. v. M. l.c. 
Hab.: Mount Bellenden Ker, at an elevation of about 5000ft., Bayer and Davidson. 
So far as the earpologic characteristics are concerned, this plant is clearly referable to the 
genus Pentapanax, and differs from its ally P. l.esckenaultii in smaller not serrulated leaflets 
on longer stalklets, in its umbels containing far less flowers, and in the less indented calyx-limb. 
Perhaps, also, the structure of the flowers and colour of fruit may prove different. F. r. M l.c. 
4. MACKINLAYA, F. v. M. 
(After J. Mackinlay.) 
Calyx with 5 prominent lobes. Petals unguiculate, with long induplicate 
points, valvate in the bud. Stamens 5. Disk broad, the margin undulate. 
Ovary 2-eelled. Styles 2, at first erect, afterwaids recurved. Fruit very flat, the 
endoearp cartilaginous, forming 2 separate pyrenes, the exocarp succulent. — 
Shrub or tree. Leaves digitately compound. Flowers polygamous, articulate on 
the pedicels, in a large compound terminal umbel, with general and partial 
involucres of narrow bracts. 
The genus is limited to a single species, endemic in Australia, differing from Panax chiefly in 
inflorescence and in the petals resembling those of many I'mbelliferte. — Benth. 
1. 1YE. macrosciadia (umbels long), 1\ r. M. Fray in. iv. 120; Bentli. FI. 
Austr. iii. 383. A slender shrub or small tree, quite glabrous. Leaves with the 
common petiole sheathing at the base, but without distinct stipules ; leaflets 3 to 
7, usually 5, petiolulate, ovate or oblong, shortly acuminate, entire or with a few 
short distant teeth, 4 to Bin. long, membranous at least at the time of flowering. 
Umbels 3 times or even 4 times compound, with numerous rays, the primary 
ones often 4 to 5in. long, the secondary and tertiary umbels compact. Involucres 
both general and partial of several linear or linear- lanceolate bracts, much shorter 
than the rays. Calyx-lobes acute or acuminate. Fruits when perfect about 7 
lines broad and 5 lines long, but 1 carpel often deformed and semi-abortive. —

5. ASTROTRICHA, DC. 
(Hairs of plants star-like.) 
Calyx-teeth minutely prominent. Petals 5, valvate, usually pubescent outside. 
Stamens 5. Disk broad and not thick, the margin often prominent. Ovary 
2-celleh. Styles 2, distinct, at first erect, afterwards recurved. Fruit flattened
