XCV. YERBENACEJE. 
[ Premna . 
Very closely allied to some maritime forms of P. integrifolia but the leaves more obtuse, of a 
firmer consistence, and the corolla tube shorter. These characters may not. however, prove 
constant. — Bentli. 
The form of the pith in the stem of this is most remarkable. The central hollow or pith- 
tube is ribbed on the inner surface with about 14 prominent and numerous line-like ribs ; to 
these are attached at distances of about three lines thin filmy disks or seplse of a pale-pink 
colour and tough consistency, which may be removed from the stem readily without injury ; 
those of the stem noticed when thus removed measured eight lines in diameter. Wood brown.

Wood used for spears and fire sticks. Both, l.c. 
Yar.? velutina. Leaves softly tomentose, on both sides, otherwise the foliage and flowers 
quite those of A. oht usi/oda— Rockingham Bay, Dallacliy , who notes that it is a small tree with 
a spreading head. 
2. P. integrifolia (leaves entire), Linn ■ Yar.; Benth.Fl. Austr. v. 59; 
A tree or shrub, either quite glabrous or with a slight-pubescence on the foliage 
and inflorescence. Leaves ovate, shortly accuminate, broad or rather narrow, 
usually rather smaller than in P. obtusifolia. Inflorescence and calyx entirely as 
in that species, but the corolla (in the Australian form) larger, the tube nearly 
twice as long as the calyx. — P. ovata and P. melia, R. Br. Prod. 512 ; Schau. in 
DC. Prod. xi. 637. 
Hab.: Islands of the Gulf of Carpentaria, B. Brown. 
The specimens I saw in Brown’s herbarium did not appear to me to be at all different from 
some Asiatic ones of P. integrifolia, a very common sea-coast plant united by Schauer in DC. 
Prod. vi. G32 with P. scrratifolia, Linn., under the latter name, which, however, appears to be 
the least appropriate of the two Linnsan ones for the consolidated species. The whole question 
however of the species of Premna requires a thorough revision. — Bentli. 
3. P. limbata (referring to the expanded calyx), Bentli. FI. Austr. v. 59. 
A climbing shrub (Dallacliy), the young branches and inflorescence minutely 
tomentose. Leaves ovate, mostly acuminate, rounded or broadly cordate at the 
base, 4 to Gin. long, membranous, glabrous or pubescent along the veins 
underneath, the petioles lin. long or more. Panicles trichotomous, but not so 
spreading as in P. obtusifolia and the flowers larger, the pedicels often above 1 
line long. Calyx fully 1 line long, the margin slightly expanded into broad very 
short obtuse or retuse teeth. Corolla-tube twice as long as the calyx, the upper 
inner lobe not much larger than the others. 
Hab.: Kockingbam Bay, Dallacliy. 
4. P. Dallachyana (after J. Dallachy), Bentli. FI. Austr. v. 59. “ Yel.” 
Morehead River, Both. A fine spreading shrub ( Dallacliy ), the younger branches 
and inflorescence minutely tomentose, the older branches glabrous with a light 
coloured bark, the foliage usually drying black. Leaves ovate, acuminate, 
entire, obtuse or narrowed at the base, mostly 2 to 3in. long, glabrous or 
scarcely pubescent along the principal veins underneath. Panicles trichotomous, 
corymbose, not large. Calyx scarcely 1 line long, more or less distinctly 
5-toothed, the teeth very short, acute or obtuse but not dilated. Corolla- 
tube twice as long as the calyx and considerably dilated upwards, 
hairy inside at the throat, the lobes broad, the upper inner one larger 
than the others but entire. Stamens usually longer than the corolla. Drupe 
depressed-globular, not usually exceeding the calyx. 
Hab.: Port Denison and in the scrub about Edgecombe Bay, Dallacliy; Fort Cooper, 
Bowman. The calyx-lobes are more obtuse and irregular in the Edgecombe Bay specimens than 
in the others. 
Wood used for making fire-sticks.— Both. l.c. 
5. P. Tateana (after T. Tate, botanic collector of Hann’s Expedition), 
Bail. Bot. Bull. iv. A tall shrub, bark light-coloured, striated and more or less 
covered with scattered verrucae. Leaves glabrous, broad lancolate, of thin
