 Nomenclature
Scientific Name:
Veronica macrocalyx var. humilis (G.Simpson) Garn.-Jones in Garnock-Jones et al., Taxon 56: 577 (2007)
Synonymy:
  • Hebe macrocalyx var. humilis G.Simpson, Trans. Roy. Soc. New Zealand 79: 428 (1952)
  • Hebe haastii var. humilis (G.Simpson) L.B.Moore in Allan, Fl. New Zealand 1, 940 (1961)
  • Leonohebe haastii var. humilis (G.Simpson) Heads, Bot. Soc. Otago Newsl. 5: 6 (1987)
Lectotype (designated by Moore, in Allan 1961): from a plant in cultivation at Geo Simpson’s garden Dunedin, collected from slopes of Mt French at 1525 m altitude, G. Simpson & J. S. Thomson, Feb 1932, CHR 76135
Etymology:
The epithet humilis refers to the low-growing growth form of this variety.
 Description

Leaves mostly 4–11 mm long, rarely shorter; lamina weakly keeled; keel extending to apex; margins reddish and not translucent, either papillose or erose (sometimes both on the same leaf), sometimes minutely glandular-hairy, especially when young. Calyx lobes red-tipped.

 Recognition

Specimens from shaded sites in Nelson and Marlborough, such as in sink-holes, tend to have a more lax and sprawling habit, with longer internodes, darker green, spathulate to orbicular and sometimes sparingly toothed leaves, although toothed leaves also occur rarely on plants from sunny sites.

 Distribution

South Island: Nelson, Sounds Nelson (Mt Richmond), western Marlborough, and Westland north of about Lewis Pass.

 Habitat

Rocky alpine herb-fields, debris, and scree. Recorded elevations range from 1100 to 1908 m.

 Biostatus
Indigenous (Endemic)
 Cytology

2n = 42 (see Bayly & Kellow 2006, as Hebe macrocalyx var. humilis).
