to HOOKER intermediate Betwern the Szsymbrieae and the ZLepidineae; Noto- 
thlaspi (Crucif.), contains 2 species, placed by PRANTL in the 7%elypodieae- 
Stanleyinae next to Pringlea of Kerguelenland; /rerba (Saxifragac.) monotypic, 
belongs to the section Escallonioideae and nearest to Brexia of Madagascar 
and the Seychelles; Carpodetus (Saxifragac.), monotypic, also belongs to the 
Escallontordeae and placed by ENGLER between the Australian-New Caledonian

possibly monotypic, closely related to the almost endemic Carmichaelia; 
Chordospartium (Legum.), monotypic, confined so far as known to two valleys 
of the North-eastern district, nearest to Corallospartium but also possessing 
characters of Carmichaelia and the following genus; Notospartium (Legum.), 
contains at any rate two species, it differs from the above Zegumznosae in its rather 
long, linear many-jointed pod and would be accorded generic rank by any 
 systematist; Alectryon (Sapindac.), contains two closely-related species; En- 
felea (Tiliac.), monotypic, related to the South African Sparmannia; Hoheria 
(Malvac.), contains at least three species all of which are closely related, 
belongs to the Malveae-Sidinae and related to the indigenous genera Pla- 
gianthus and South American Gaya; Tetrapathaeca (Passiflorac.) monotypic, 
y some united with Passiflora; Stilbocarpa (Araliac.), contains three species, 
two of which are confined to the Subantarctic district and the other to the

North American, East Asian and Australian genus; Anisotome (Umbell.) contains 
19 species, closely related to the almost endemic Acıphylla, as also to 
Ligusticum; Coxella (Umbell.), monotypic and confined to the Chatham Islands, 
nearest to Aciphylla, but has also been referred to Gingzidium, L ıgusticum PR 
Angelica, Corokia (Cornac.) consists of three species one of which is confined

—E. Asian Helwvingia and Cornus, a genus wide-spread in the Northern Hemis- 
sphere; Myosotidium (Borrag.), monotypic, and confined to the Chatham Islands, 
a distinct genus belonging to the Borraginoideae-Cynoglosseae, its nearest ally 
appearing to be Paracaryum of Central Asia and the Mediterranean; Teueridium

kioldia, Siphonidium (Scroph.), monotypic, closely related to Euphrasia, a com- 
mon genus in New Zealand, but amply distinct; Rhabdothamnus (Gesneriac.), 
monotypic, forms with the New Caledonian Coronanthera and the Lord Howe 
Negria the small group Cyrtandroideae- Coronanthereae-Coronantherinae; Al- 
seuosmia (Caprifoliac.) consists of four species, a distinct genus perhaps more 
closely related to Lonicera than to any other, but differing from all other Cap- 
rifoliaceae in its alternate leaves; Colensoa (Campanulac.), monotypic, closely 
related to Pratia, a common genus in New Zealand with which it is united 
by SCHÖNLAND; Oreostylidium (Stylidiac.). monotypic, related to the Australian
