Puccinia komarovii: teliospore

teliospore. The constriction between the cells of the teliospore in the illustrated material is much weaker than indicated by Termorshuizen & Swertz (2011a).

gall

No host plant alternation. Aecia orange, cupulate, in dense groups mainly on the stems; the cause strong, up to 10 cm long galling. Uredinia and telia hypophyllous, on conspicuous, pale leaf spots. Uredinia cinnamon brown; spores spinuolose, with but one germination pore, surrounded by a spine-less zone and capped by a low papilla. Telia chestnut brown; spores 2-celled, wall smooth, pedicel short, hyaline, deciduous.

hostplants

Balsaminaceae, monophagous

Impatiens amphorata, balsamina, capensis, firmula, parviflora, scabrida, thomsonii.

Not on I. noli-tangere. Tanner ao (2015a) describe a var. glanduliferae, collected by them in the Himalaya, that is strictly associated with I. glandulifera. The variety may possibly de deployed in the control of this highly invasive species.
