Abstract
The unrecorded androecia and feebly described gynoecia in Indian specimens of two Porella species, namely, P. densifolia subsp. appendiculata (Steph.) S. Hatt. and P. campylophylla var. ptychantha (Mitt.) F. Shaheen & S.C. Sriv., collected from Kumaun region in the state of Uttarakhand in Western Himalaya, are being described and compared besides observing variations in vegetative features of the plants.
Highlights
In course of survey of the liverwort flora of Kumaun Region in the State of Uttarakhand in Western Himalaya, we came across two profusely fertile Porella species, namely, P. densifolia subsp. appendiculata (Steph.) S
In order to fill the gap of details of androecia and to provide additional information on gynoecia and sporophyte structures, an effort to describe the two species has been made
Instituted as Madotheca appendiculata by Franz Stephani in 1910 from the ‘type’ locality Mussorie in Western Himalaya, the species is currently recognized as Porella densifolia subsp. appendiculata (Steph.) S
Summary
In course of survey of the liverwort flora of Kumaun Region in the State of Uttarakhand in Western Himalaya, we came across two profusely fertile Porella species, namely, P. densifolia subsp. appendiculata (Steph.) S. In course of survey of the liverwort flora of Kumaun Region in the State of Uttarakhand in Western Himalaya, we came across two profusely fertile Porella species, namely, P. densifolia subsp. It was heavily snowing for more than a week when we collected these specimens. In India (besides Nepal and China, see Hattori, 1966 and Bapna and Kachroo, 2000) is largely confined to Western Himalaya, the other taxon, namely, P. campylophylla var. Shaheen & S.C.Sriv., is recorded both from Western and Eastern Himalaya (Singh and Singh, 2006). Kashyap (1932) in his monumental work on “Liverworts of Western Himalaya and Panjab Plain” has described the former species as Madotheca appendiculata Steph., yet their description lacks the. In order to fill the gap of details of androecia and to provide additional information on gynoecia and sporophyte structures, an effort to describe the two species has been made
