Description
|
Secunda stirps ad Sect. Martiella (v. Tiegh.) Engl. attribuenda. A prima species usque adhuc cognita, Ph. palmeri (Wats.) Engl. in Mexico vigente, primo vultu floribus racemosis atque foliis caudatis discernitur, neglecta florum magnitudine. Frutex parasiticus ramis elongatis teretibusque, ad nodos modice incrassatis, internodiis 2-4 cm. longis. Folia ovato-caudata, basi subrotundata, e medio apicem versus gradatim attenuata, extremo apice valde angustata, coriacea, nervis supra tantum subtiliter impressis, 5-9 cm. longa, 3-5 cm. lata; petiolis 1-2 cm. longis. Racemi vulgo 2 ad singulas axillas, longitudine ad 4 cm. usque, laxi, rachidi quadrangula; floribus oppositis, neque in ternationibus aggregatis et androgynis. Pedicelli circa 1-2 mm. longi, teretes. Bractea trangulari-acuta, 2 mm. longa; bracteolae duae pro flore, liberae a bractea et hac duplo minores, conformes. Ala- bastra cylindrica, apice optime apiculata, siccitate nigrescentia. Calyculus ad marginem membranaceum 0.5 mm. altum tantum reductus. Perigonium hex- amerum, ad summum 1 cm. longum, caeterum ut in aliis generis speciebus. Fructus latent.

Note
|
On vegetative characters alone this remarkable plant resembles Struthanthus marginatus, with which it has been confused; however, it suffices to observe the pointed buds as well as the solitary flowers at each pedicel of Ph. panamensis to make ready distinction. The only other species of the Section Martiella is Ph. palmeri (Wats.) Engl., whose leaves rounded at the apex together with its red flowers, to 4 cm. long- not to mention the inflorescence (see Latin diagnosis) -place it far from the above.
