Species rarely found in park

Snow tōtara (Podocarpus nivalis), Bog Mingimingi (Androstoma empetrifolia), a small whipcord hebe (Hebe subsimilis var. astonii) and a prostrate form of Hebe odora are not threatened nationally but are rare and  local on the Pouākai Range. Interestingly they are not found on the rest of the Egmont National Park.

Snow tōtara is found on Henry and Maude Peaks, as well as the Dover Ridge, and is an outlier population from the main North Island concentration of the species in Tongariro National Park. It is a spreading woody shrub with broadly domed patches.

Gene exchange, as a result of wind-blown pollen from mountain tōtara, leads to intermediate or hybrid plants. It is unclear whether the form on the Pouākai Range is the same as the type in Tongariro National Park or has some gene pollution from P. laetus.

It is understood no more than 20 Bog Mingimingi are present in poorly drained red tussock (Chionochloa rubra) tussockland near the tarns on the crest of the Pouākai Range. These shrubs flower between November to February and red drupes are present from January to April. They are found throughout New Zealand in alpine and subalpine areas usually in poor peaty soils.

Small whipcord hebe can be found on exposed sites such as the ridge crest to the north of the old Pouākai hut site and on Henry Peak where it occurs  with Snow tōtara.

A prostrate form of Hebe odora has been recorded on exposed ridge crests of the Pouākai Range and there may be an unnamed variety of the more widespread erect form of Hebe odora characteristic of Chionochloa rubra tussockland.

North Island species rarely found in park

Egmont National Park is the only North Island locality Mountain Lacebark (Hoheria glabrata) and Hector’s sedge (Carex hectori).

Mountain lacebark has not been seen since the 1960s when it was recorded by Tony Druce and Geoff Kelly on a vegetation transect being measured near the old North Egmont Chalet. Despite several searches it has never been seen again.

Hector’s sedge was found by Tony Druce in the 1960s in herbfield vegetation on the Pouākai Range peak informally named Tatangi (meaning sedge) by Tony Druce. It also has not been sighted for more than 40 years.
