PlantLife SA, Volume 49.6, July 2020. Helichrysum field-identification


An aid to field identification of some Helichrysum species from the summer rainfall region of South Africa

Text by Kate Grieve, photos by Graham Grieve and John Burrows


Introduction
There are about 245 species of Helichrysum in South Africa, approximately half the world's population of this genus.  They are particularly well represented in KwaZulu-Natal (KZN) and this can lead to some confusion.  Here are some of the common species in the summer rainfall region of South Africa (excluding the high Drakensberg) that are similar and may be problematic for identification in the field.

This article covers a group of plants with an inflorescence of several clustered flower heads and with leaves mostly around the base of an erect, unbranched stem.

 
This photograph shows an inflorescence comprising a cluster of individual flower heads, each one surrounded by papery flower bracts. 

H. acutatum DC.

Helichrysum acutatum

Helichrysum acutatum

Sticky Everlasting (e), Sewejaartjie (a), Taaisewejaartjie (a), Tontelbossie (a), Uzangume (z)
Flowering stem up to 600 mm tall; plants may occur singly (particularly inland) but are often found in clumps.  Most of the leaves are tufted at the base of the stem but stem leaves, when present, decrease in size upwards; leaves greyish, woolly and conspicuously 3-veined from the base. Flower heads oblong, pointed, in dense clusters in flat-topped inflorescences; bracts sharply pointed, closely overlapping, shiny, pinkish beige at first becoming lemon yellow. Flowering time: September to January. Grassland, sea level to 1950 m elevation. Range: Eastern Cape, KZN, Gauteng, Mpumalanga and Limpopo.


H. allioides Less.

 
Helichrysum allioides

Stem up to 650 mm tall. Leaves long (up to 300 mm) and narrow, the bottom half a long and wiry petiole, smooth and dark green above and white beneath, 3-veined. Flower heads cup-shaped, small (4-6 mm diam.), in a compact, flat topped inflorescence; bract tips blunt, yellow (outer bracts sometimes purplish). Flowering time: August to December. Grassland, sea level to 1250 m elevation. Range: Eastern Cape, KZN and Mpumalanga.


H. appendiculatum Less.

Helichrysum appendiculatum showing recurved bracts

Flowering stem one or several, up to 500 mm tall. Leaves mostly at the base of the stem but stem leaves decreasing in size upwards, both surfaces woolly at first but upper surface becoming smooth with age. Flower heads cup-shaped, approximately 10 mm diam., tightly clustered at first becoming looser later; bracts at first red, brown or russet becoming yellowish or creamy white, dull, tips pointed, curved outwards.  Flowering time: mainly December to February.  Grassland, sea level to 2100 m elevation. Range: Western Cape, Eastern Cape, KZN, Mpumalanga and Limpopo.


H. auriceps Hilliard

 
Helichrysum auriceps

Flowering stem up to 600 mm tall, all parts grey-woolly. Leaves in a basal rosette, a few smaller leaves on the stem, 3-veined. Flower heads cup-shaped, many in a tight round cluster 45 mm diam., the base webbed with wool; bracts glossy, bright yellow. Flowering time: mainly February to April.  Grassland from sea level to 2000 m elevation. Range: south western half of KZN.


H. cephaloideum DC.
Ibhade (z), Mosuoane-oa-thaba (ss)

Helichrysum cephaloideum


Several flowering stems up to 400 mm tall, all parts grey-woolly.  Leaves on the ground in a basal rosette but often withered at flowering, a few smaller leaves on the stem. Flower heads cup-shaped, several in a compact cluster approximately 30 mm diam.; bracts glossy bright yellow, loosely overlapping. Flowering time mainly December to March. Grassland, highlands. Range: Eastern Cape, KZN, Free State, Gauteng, Mpumalanga and Limpopo.

Note: The H. cephaloideum group includes H. longifolium and H. mixtum; a similar species is H. auriceps.


H. griseum Sond.
 
Helichrysum griseum

Helichrysum griseum


Helichrysum griseum


H. pilosellum and H griseum

Flowering stem up to 700 mm tall, one or several. Leaves only 3 or 4, ovate (200 x 80 mm), green and harshly hairy above and white-felted beneath, faintly 5–9 veined from the base and net veins visible. Flower heads cup-shaped, in a large inflorescence that is clustered at first but becomes lax and more open; bracts red to pink, sharply pointed, curved outwards. Flowering time: August to October (one of the first to flower after fire). Grassland, up to 1200 m elevation.  Range: East London to Umvoti.


H. longifolium DC.

 
Helichrysum longifolium

Similar to H. cephaloideum but can be a bigger plant and differs in having long lanceolate leaves (up to 250 mm long), smooth above and hairy or felted beneath.  Flower heads cup-shaped, in an inflorescence that is initially clustered but becomes open; bracts glossy yellow, acute. Flowering time: November to January. Grassland, mostly coastal. Range: East London in the Eastern Cape to the border of KZN with Mozambique.


H. miconiifolium DC.

Rootstock topped with old leaf fibres, flowering stem up to 600 mm tall, thinly woolly. Leaves mostly at the bottom of the stem and decreasing in size upwards; leaf elliptic, narrowing to a thin wiry petiole, upper surface green and lower white-felted, 3-veined from the base, margins of stem leaves rolled under. Flower heads cup-shaped, many in a flat-topped inflorescence; bracts glossy, lemon yellow or light brown.  Flowering time: November to February.  Grassland from the coast to 2000 m but common in the mountains. Range: Eastern Cape, KZN, Free State, Gauteng, Mpumalanga and Limpopo.


H. mixtum (Kuntze) Moeser var. mixtum


Helichrysum mixtum
 
Similar to H. cephaloideum, this species combines the foliage of H. cephaloideum with the loose inflorescence and pointed bracts of H. longifolium. Leaves approximately 100 mm long, elliptic, grey-woolly. Flower heads cup-shaped, in a fairly loose cluster; bracts sharply pointed, glossy yellow. Flowering time November to January (March to April in Gauteng). Grassland. Range: eastern half of Eastern Cape, KZN, Gauteng and Mpumalanga.
