250 RUBIACEH. [Coprosma. 
Kermabec Istanps: Abundant on Sunday or Raoul Island, ascending to 
the tops of the hills, alt. 1700 ft., McGillwray, T. F. C. July-August. 
A very distinct species, at once recognised by the comparatively narrow 
thin and membranous leaves and lax inflorescence. 
11. C. tenuifolia, Cheesem. in Trans. N.Z. Inst. xviii. (1886) 
315.—A sparingly branched shrub 8-15 ft. high, glabrous, or the 
petioles and midribs of the young leaves minutely hairy; branches 
slender, terete; bark pale. Leaves 14~4 in. long, ovate or oblong- 
‘ovate to ovate-lanceolate or elliptic-lanceolate, acute or acuminate, 
narrowed into slender petioles +—#in. long, thin and membranous 
or rarely subcoriaceous, dull brownish-green above, paler below ; 
veins conspicuous on both surfaces, finely reticulated. Stipules 
rather large, broadly deltoid, margins ciliate when young. Male 
flowers crowded in axillary 3—8-flowered fascicles or terminating 
arrested branchlets. Calyx apparently wanting. Corolla campanu- 
late, 4-5-lobed. Female flowers not seen. Fruit in dense fascicles 
of 3-8 on short lateral branchlets, +-4 in. long, ovoid or oblong.—

Nort Isuanp: Te Aroha, Pirongia, and Karioi Mountains, T. F.C. ; Mount 
Hikurangi, Adams and Petrie! Lake Waikaremoana, Bishop Williams ! 
#. Best! Ruahine Mountains, Colenso! Mount Egmont Ranges, 7. Ff. C.; 
abundant in the Upper Wanganui and Rangitikei Valleys, Kirk! 1000- 
-4000 ft. 
Distinguished from C. robusta by the membranous pale-brown leaves and 
smaller glomerules. From C. acutifolia it is separated by the broader leaves 
with coarser venation and by the compact inflorescence. 
12. C. arborea, 7’. Kirk in Trans. N.Z. Inst. x. (1878) 420.—A 
closely branched round-headed tree 15-30 ft. high; trunk 6-18 in. 
diam.; branchlets slender, puberulous towards the tips. Leaves 
1-24 in. long, ovate-spathulate or orbicular-spathulate, obtuse or 
retuse, suddenly narrowed into winged petioles +~-2in. long, coria- 
ceous, yellow-green above, often reddish beneath; veins reticu- 
lated; margins flat. Stipules short, deltoid, ciliate when young. 
Flowers densely crowded in many-flowered rounded glomerules or 
heads, terminating short axillary branchlets or at the ends of 
larger shoots. Male flowers: Calyx narrow, deeply divided into 
4-5 ciliate lobes. Corolla short, 4in. long, campanulate, deeply 
4-5-lobed. Females: Smaller and shorter, in 4-12-flowered 
fascicles. Calyx-limb 4-5-toothed. Corolla tubular. Drupes 
closely packed, broadly oblong or almost globose, +in. diam., 
colourless and translucent.—Cheesem. in Trans. N.Z. Inst. xix. 
(1887) 236; Kirk, Forest Fl. t. 132; Students’ Fl. 234. 
Nortu Istanp: Not uncommon in woods from the North Cape to the 
Lower Waikato. Sea-level to 1500 ft. October-November. 
One of the largest species of the genus, and one of the most distinct. The 
calyx of the male flowers is better developed and has deeper divisions than in 
any other species.
