B.—Distribution of Species and Citation of Specimens

This section of the paper discusses species of succulents occurring in habits other than the coastal cliffs and species mentioned earlier from coastal cliffs but which occur in other habitats, and lists voucher specimens deposited in the herbarium of the Botany Division, D.S.I.R., Christchurch. Unless stated otherwise, the writer was responsible for observations and collection of specimens.

• 1. †Aeonium arboreum (L.) Webb et Berth. (Crassulaceae). Anderson's Bay, Dunedin, A. J. Healy & K. W. Allison, 1954 (83283).

• 2. †A. ciliatum (Willd.) Webb et Berth. (Crassulaceae). Sumner, Christchurch, 1954 (88956, 91554).

• 3. †Aptenia cordifolia (Linn. f.) N.E. Br. (Ficoidaceae). Roadside banks, often under Sarothamnus scoparius, Thorndon, Wellington 1953 (85716); Red-cliffs, Christchurch, 1954 (88959); normal scrambling form, Oamaru, 1954 (91425); erect, tufted form, Oamaru, 1954 (88470, 91424).

• 4. Cotyledon orbiculata L. (Crassulaceae). Additional to its occurrence in the Sumner-Redcliffs locality, this species was observed (May, 1941) to be well established on steep, eroded mudstone cliffs along the north bank of the lower Waipara River, North Canterbury; Sumner, H. H. Allan 1935 (17395); Redcliffs-Sumner, 1954 (83276).

• 5. †Crassula multicava Lem. (syn., C. quadrifida Baker) (Crassulaceae). Established on north-west aspect only of a deep cutting, Wadestown, Wellington, a garden escape from sections above the cutting, C. M. Smith, 1957 (98660).

• 6. †Crassula tetragona L. (Crassulaceae) Sumner 1954 (91408).

• 7. †Drosanthemum floribundum (Haw.) Schwant. (Ficoidaceae). Blowhole Island, Tauranga, M. E. Gillham, 1957 (98669); Sumner, Christchurch, 1954 (91494).

• 8. †Echeveria secunda Booth (Crassulaceae). Occasional as a persistent garden outcast on dry rocky places: near Diamond Harbour, Lyttelton, 1955 (89537); Birdling's Flat, Banks Peninsula, R. Mason, 1954 (88662).

• 9. †Mesembryanthemum sp. (Ficoidaceae). This species occurs in all habitats discussed in the preceding section of the paper, and comes close to M. chilensis Mol., but its identity cannot be determined with certainty; Oamaru, 1954 (91509).

• 10. †Mesembryanthemum sp. (Ficoidaceae). Characterized by the papillose leaves and whitish flowers, this species occurs as a garden escape about banks and road cuttings, Timaru, C. M. Smith, 1957.

• 11. †Othonna capensis Bailey (Compositae). Sumner, Christchurch, 1956 (98050).

• 12. †Sedum album L. (Crassulaceae). This species has been found in a number of South Island localities, and it is probably much more widespread than the following distribution would indicate. It appears to have economic significance in several localities as a weed of ballast along railway tracks; roadside, base of coastal cliffs, Scarborough, Christchurch, 1955 (89495); railway ballast and embankments, Kowhai Bush, Canterbury, H. Talbot, 1954 (89496); railway ballast, Rolleston, 1956 (98627), railway ballast, Rakaia, 1956; rocky faces, near Alexandra, 1957 (98606); with Pellaea falcata and Arenaria serpyllifolia L. on rocky faces, Teviot River, near Roxburgh, 1957 (98522); crevices of rock walls about cattle-trucking yards, and with Arabidopsis thaliana (L.) Heynh. on railway ballast,
