XXIV. SAXIFRAGES. 
5. ACKAMA, A. Cunn. 
A small tree. Leaves opposite, pinnate, stipulate. Flowers small, pa- 
nicled, unisexual. — Calyx interior, 5-partite ; lobes valvate. Petals 5, liuear- 
spathulate, inserted beneath a 10-lobed disk, about as long as the calyx. 
Stamens 10 ; filaments filiform, the alternate longer ; anthers didymous. 
Ovary free, hirsute, 2-celled ; styles 2, filiform, persistent ; ovules very nu- 
merous, on parietal placentas. Capsule small, coriaceous, turgid, 2-celled, 
septicidally 2-valved, valves gaping inwardly. Seeds turgid, ovoid, apiculate ; 
testa smooth, lax, pilose; embryo cylindric, albumen scanty. 
1. A. rossefolia, A. Cunn. ; — FI. N. Z. i. 79. ii. 329. Tree 30-40 
ft. high. Leaves pubescent, imparipinnate, 3-10 in. long. Leaflets in 3—6 
pairs, subsessile, linear-oblong, acute, acutely serrate, 1-2 in. long, rather 
membranous, the upper larger; stipules deciduous, leafy, toothed. Flowers 
small, A- in. diam., in spreading, branched panicles, sessile on the branchlets. 
Capsule very small. 
Northern parts of the Northern Island. Woods at the Bay of Islands, not uncommon, 
A. Cunningham, etc. A. Gray (Bot. U. S. Expl. Exped. i. 672) regards this as a subgenns 
of Weinmannia , but I think erroneously. 
6. WEINMANNIA, Linn. 
Shrubs or trees. Leaves opposite, stipulate, 1-3-foliolate or pinnate. 
Flowers racemose, small. — Calyx inferior, tube short; limb 4-5 -partite, im- 
bricate. Petals 4 or 5, inserted under the edges of a lobed disk, imbricate. 
Stamens 8 or 10; filaments filiform; anthers didymous. Ovary free, ovoid or 
conical, 2-celled, narrowed into two beaks ; styles filiform ; ovules few or 
many, placentas inserted above the middle in the axes of the cells. Capsule 
small, coriaceous, 2-celled, septicidally 2-valved, valves gaping inwardly. Seeds 
oblong reniform or subglobose ; testa membranous, often pilose ; embryo 
terete ; albumen fleshy. 
A large Indiau, Pacific Island, Australian, and S. American genus. 
Branchlets, peduucles, and petioles pubescent. Leaves 3-foliolate or pinnate 1. W. silvicola. 
Branchlets, peduncles, and petioles glabrous. Leaves 1-foliolate ... 2. W. racemosa. 
1. W. silvicola, Bunks and Sol.; — FI. N. Z. i. 79. A small tree, 
20-30 ft. high, with dark bark, the young leaves, branchlets, inflorescence, 
and costa of leaf below all pubescent or glabrescent. Leaves opposite, 1-3- 
foliolate or imparipinnate (on the same specimen), 1—3 in. long; leaflets 
variable, 1-2 in. long, obovate-oblong or lanceolate, acute or acuminate, 
coarsely serrate, coriaceous, punctate beneath, young ones membranous, 
glabrous or pubescent below, usually narrowed into the petiole; stipules leafy, 
oblong, entire or toothed. Racemes 2-4 in., slender, many-flowered. Flowers 
T V in. diain., pedicelled, white. Capsule glabrous or minutely hairy, in. 
long. — IF. fuchsioides and IF. betulina, A. Cunn. 
Abundant in woods throughout the Northern Island, and in the northern part of the 
Middle Island, Banks and. Solander, etc. An exceedingly variable plant, of which L made 
three varieties in the New Zealand Flora, but find that these do not hold good: the most 
marked forms are a larger, often pinualcd-leaved oue, with almost tomentose branchlets.
