Papilionaceae.
Calycotome spinosa (Linn.) Link. The distribution given by Allan (1940: 120) is for the vicinity of Palmerston North; this plant has now been noted as established on roadsides, Bunnythorpe; Sanson; Stanway, near Feilding; Shannon (now eradicated).
Lathyris pratensis Linn. Recorded from Ashburton County by Smith (1904: 218), its occurrence at Gore was noted by Healy (1944: 224); it has been found at Wainui Bay, Bank's Peninsula, Mrs. E. Brooker 51399, and is established along the railway line near Mangaroa, North Island, 33998.
Melilotus albus Med. Allan (1940: 123) gives the distribution as Canterbury and Napier; it is established in waste places about Seddon, Marlborough; waste land, Thorndon, Wellington.
Trifolium parviflorum Ehrh. Previously recorded from Feilding by Allan (1940: 291) and Marlborough by Healy (1944: 224), the species is now well established on stony land near the mouth of the Hutt River, Wellington, 45934, 45942.
Trifolium suffocatum Linn. Previously recorded only from Blenheim [Boulder Bank, Wairau Bar] by Allan (1940: 291), the species has been found in depleted Danthonia pasture, Wither Hills Soil Conservation Reserve, Blenheim, 33639; roadside, Dashwood Pass, Marlborough, 36309; stony river terrace, Culverden, 33598.
†Trifolium tomentosum Linn. The present concept of T. resupinatum Linn. in New Zealand covers two distinct plants; there is the true T. resupinatum Linn, which constitutes the T. resupinatum Linn, var. typicum Fiori et Paol. of Hegi and other European botanists, and T. tomentosum Linn, which constitutes the T. resupinatum Linn. ssp. tomentosum (Linn.) Gibelli et Belli of European authors.
There occur in New Zealand, therefore, a group of three species of Trifolium with inflated fruiting calyces which can be distinguished by the following key:
| 1.Stems creeping, rooting at the nodes; flower head with involucre of lobed bracts ± lengths of calyx tube | T. fragiferum |
| Stems ± prostrate, not creeping or rooting at nodes; involucre of lobed bracts absent | 2 |
| 2.Fruiting calyx with two short recurved teeth ± hidden in woolly tomentum; peduncles shorter than leaves | T. tomentosum |
| Fruiting calyx conspicuously reticulate, with two long, divergent teeth; peduncle longer than leaves | T. resupinatum |
The following specimens in the herbarium of the Plant Research Bureau give some concept of the distribution of the two species: T. resupinatum Linn.—Dargaville, H. H. Allan 18450; Mangonui, collector not stated, 3456; Whangarei, E. H. Arnold 33934; North Auckland, P. W. Smallfield 3507; Bucklands, Auckland, M. Hodgkins 8947; Kopu, near Thames, J. H. Hudson 45935; Ellesmere [Canterbury?], collector not stated, 802. T. tomentosum Linn.—
