XXIII. ROSACE.E. 
1. RUBUS, Linn. 
Climbing shrubs (rarely erect or herbaceous) ; stems usually prickly. Leaves 
simple or compound. Flowers panicled (rarely solitary). — Calyx-tube open; 
lobes 5, large, persistent. Petals 5, rarely more, orbicular or obovate. Sta- 
mens numerous. Carpels numerous, small, crowded on a small torus ; style 
lateral or subterminal, short, stigma capitate; ovules 2, pendulous. Fruit of 
small, globose, fleshy drupes. 
A very large genus (to which the Bramble, Raspberry, and Dewberry belong), especially 
in the west of Europe and Himalaya mountains, found also iu almost all other parts of the 
world, except the hottest and driest. 
1. R. australis, Ford. ; — FI. N. Z. i. 53. t. 14. A lofty climber, armed 
with scattered recurved prickles ; branches very slender, pendulous. Leaves 
coriaceous, 3-5-nate, or pinnate with 2 pairs of leaflets and a terminal one; 
leaflets on long petioles, very variable in shape, ovate cordate oblong lanceo- 
late or reduced to prickly midribs, 2-5 in. long, coarsely serrate or toothed, 
sinning above, glabrous pubescent or tomentose beneath. Flowers very 
numerous, in branched, prickly, downy panicles, in. diarn., fragrant. 
Calyx-lobes ovate, obtuse. Petals linear-oblong, pink or whitish. Stamens 
numerous. Female flowers rarer. Drupes numerous, with short, subterminal 
styles, when ripe yellowish, juicy, austere. 
Var. a. glaber, FI. N. Z. 1. c. Leaflets 3-5-nate or pinnate, ovate-cordate, glabrous. 
Var. /3. schmidelioides , FI. N. Z. he. Leaflets 3-5-uate or pinnate, ovate or cordate, 
pubescent or tomentose below. — R. schmidelioides , A. Cunn. 
Var. y. cissoides, FI. N. Z. 1. c. Leaflets 3-5-uate, quite glabrous, linear or elliptical- 
lanceolate, sometimes reduced to midribs. — R. cissoides, A. Cunn. 
Abundant in the skirts of woods throughout the islauds, Banks and Solander ; aud all the 
varieties found as far south as Otago. Probably the same as au Australian species of which 
I have seen incomplete specimens only. These varieties, though united by every interme- 
diate form, keep their characters under cultivation. 
2. POTE3STTILLA, Linn. 
Herbs (or rarely small shrubs), often silky woolly or pubescent, with com- 
pound (rarely simple) leaves, and 1- or more flowered leafy scapes or pedun- 
cles. Flowers hermaphrodite. — Calvx-tube open ; lobes 4 or 5, alternating 
with 4 or 5 smaller outer lobes or bracteoles, persistent, valvate. Petals 4 
or 5, orbicular or obcordate. Stamens numerous. Ovaries numerous, small, 
crowded on a small torus; styles lateral or basal, stigmas capitate; ovule 1, 
pendulous. Achenes numerous, dry, with small styles. 
A very large genus in the northern temperate and arctic zones, very rare in the southern. 
1. P. anserma s Linn. ; — FI. N. Z. i. 54. A small stemless plant, every- 
where covered with silvery hairs ; root emitting slender runners. Leaves 3- 
6 in. long, unequally pinnate ; leaflets 5-20 pairs, the alternate ones some- 
times very small, ovate oblong or rounded, deeply incised. Scapes erect, 
villous, 1 -flowered, as long as the leaves. Flowers 1 in. diam. Calyx 
very silky and villous. Petals obovate, goldeu-yellow. Achenes and recep- 
tacle villous. 
Var. (3. Leaflets small, rounded, sessile or petioled. — P. ansermoides, Raoul.
