CACTUSPEDIA       

 


Notocactus langsdorfii
(polyacanthus)  FR
1273 Arroio dos Ratos, Rio Grande do Sul, Brazil
This plant is recognizable for numerous spines and the small-sized pale yellow flowers.
 
 

Description: Usually solitary (in the standard form), or branching.
Stem: Bright or dark green, globose to short cylindrical.  The apex is depressed and filled with whitish-grey wool.
Ribs: Well marked and sharp, with scarcely prominent chinned tubercles. The crest of the ribs typically take on a purple red hue in full sun.
Areoles: Well spaced, woolly, recessed .
Spines: Several, yellowish, strong, about 20-25 mm long, spreading or curved down and backward.
Flowers: Small, lemon yellow with glossy shining petals, up to about 2-3 cm in diameter, standing near the top, and decorated with a red pistil which emphasizes the yellow of the petals.  The buds are tomentose.
Blooming season: They bloom annually around June-July.
Remarks: Notocactus langsdorfii, together with the subordinated taxa ('leprosorum', 'longispinum', 'pulvinatus', ediewarasii', 'multiceps' and 'prolifer'), form a group of very similar and controversial southern Brasilian plants bearing small flowers and strong spination.

Notes: All species of genera Notocactus, Wigginsia and Malacocarpus have recently been transferred to genus Parodia, so the names of several plants previously accepted are now all synonyms of Parodia langsdorfii.

 

The flowers are  lemon yellow with shining glossy petals, and are very showy. The red purple stigma emphasize the yellow of the petals.

Cultivation: It is easy to grow. They like a warm bright location, does great in partial shade avoid full sun.  They need good drainage and prefer a neutral to slightly acidic compost with plenty of extra grit.
