XXXIII. UmbelliferÆ.

197 Hydrocotyle moschata.—Add to the synonyms H. com-pacta, A. Rich. in Ann. Sci. Phys. iv. (1820) 201; and H. colorata, Col. in Trans. N.Z. Inst. xviii. (1885) 260.
200 Azorella reniformis.—This was first referred to Azorella by Asa Gray in Bot. U.S. Expl. Exped. i. 698, and he should consequently be quoted as the authority.
203 A. Hookeri, Drude in Engl, and Prantl, Pflanzenf. 3, viii. 132—A name proposed to take the place of A. trifoliolata, Hook, f., which is preoccupied by a Chilian species. (Clos in C. Gay, Fl. Chil. iii. 85.)page 1138
203 10. A radians, Drude, l.c.—This is quoted as a new species allied to A. Hookeri, but no description or locality is given.
203 Eryngium vesiculosum.—Abundant near the mouth of the Awatere River, Marlborough, J. H. Macmahon!
204 Actinotus novæ-zealandiæ. — Add to the synonyms Hemiphues novœ-zealandiœ, Petrie in Trans. N.Z Inst xii (1880) 355.
209 Aciphylla Colensoi var. conspicua.—Mount Kelvin, near Westport, alt. 4500 ft., W. Townson!
209 A. squarrosa.Gingidium squarrosum, F. Muell. Veg. Chath. Is. 18, should be quoted as a synonym.
210 A. Hookeri.—Brunner Mountains, W. Townson!
211 A. Lyallii.—Lyell Mountains, alt. 3500 ft., W. Townson! From the* same locality Mr. Townson also sends a remarkable variety (?) with larger and more rigid leaves, the lower pinæ of which are trifid or again pinnate. The bracts are also longer and more squarrose, with pinnately divided laminæ.
211 5 bis. A. Townsoni, Cheesem. n. sp. —Erect, slender, smooth and grassy, often somewhat flaccid, 6–12 in. high. Radical leaves numerous, very slender, 3–9 in. long, pinnate or bipinnate at the base; leaflets 2–4 pairs, very narrow, ½–3, in. long, 1/30–1/20 in. broad, usually flaccid but tipped by a short spinous point; margins minutely crenulate; petioles long, with broad membranous sheathing bases. Scape short, leafy; bracts very numerous, usually more rigid than the leaves, with broad membranous sheathing bases and a trifoliolate or pinnately divided lamina. Male umbels numerous, compound, on long slender spreading peduncles; females much fewer and smaller, on shorter erect peduncles, almost concealed in the broad membranous bract-sheaths. Fruit linear-oblong, about ⅕ in. long; carpels 3–5-winged.
South Island: Nelson—Mount Faraday, Mount Buckland, and the Lyell Mountains, alt. 3000–4500 ft., W. Townson!
The nearest ally of this curious novelty appears to be A. Lyallii var. crenulata, from which it differs in the slender and almost flaccid habit, and in the extremely narrow leaf-segments.
212 A. Monroi. —Add as a synonym Gingidium Monroi, F. Muell. Veg. Chath. Is. 18.page 1139
214 A. Dieffenbachii.—Include among the synonyms Angelica Dieffenbachii, Benth. and Hook. f. Gen. Plant, i. 916.
216 Ligusticum antipodum.—Add to the synonyms Gin-gidium antipodum, F. Muell. Veg. Chath. Is. 18.
219 L. deltoideum.—Lyell Mountains, alt. 3000–1000 ft., W. Townson!
219 11 bis. L. diversifolium, Cheesem. n. sp.—Habit and size of L. carnosulum, and like it thick and fleshy and glaucous-green when fresh. Stems 1–4 in. long, tufted at the top of a stout tortuous rootstock. with several radical leaves at the base, and 1–3 cauline ones just below the inflorescence. Leaves as in L. carnosulum, 2–3-ternately multifid with linear-subulate ultimate segments ⅙–⅓ in. long. Umbels usually solitary, compound, terminating the stem, 1–3 in. diam.; but sometimes smaller simple or compound umbels are developed in the axils of the cauline leaves. Involucral bracts 4–6, linear, flat, acute, quite entire or rarely forked, much shorter than the umbel; rays 6–12, stout, rigid. Secondary umbels small, many-flowered; bracts of the involucels 8–12, linear, quite entire. Flowers crowded, white or pink, much as in L. carnosulum but rather larger and with more prominent calyx-teeth. Fruit not seen.
South Island: Nelson—Shingle slopes on Mount Robert (overlooking Lake Rotoiti), alt. 4000 ft., F. G. Gibbs!
I have been much puzzled with this plant, which has the habit and foliage of L. carnosulum, but differs markedly in the much smaller linear and entire involucral bracts, and in smaller simple or compound umbels often being developed in the axils of the cauline leaves. In L. carnosulum the bracts are similar to the leaves—that is, are ternately multifid, and the primary ones far overtop the umbel. There is never more than a single terminal compound umbel, and the stems are usually very short.
223 Angelica trifoliolata.—Sphagnum bogs near the summit of Porter's Pass, Canterbury, Dr. Cockayne.
