diagnosis:

Ovulate cones, averaging 5·0 cm long x }·5 cm wide, borne as single terminal units on vegetative axes with helically arranged simple or bifid leaves. Cones comprised of primary axis with helically arranged bifid bracts and axillary fertile shoots. Fertile shoots bearing twenty-five to thirty sterile scales and one to two fertile scales (rarely three to five) positioned adjacent to primary axis. One terminal inverted ovule per fertile scale. Ovules bilaterally symmetrical and winged, with rounded or cordate base and attenuated micropyle. Nucellus free from integument distal to chalaza.

Lycopodiolithes filiciformis

nomenclatorial act:
protologue/first publication
Page:
414
diagnosis:

Man glaubt beym ersten Anblick ein südliches Farrenkraut vor sich zu haben, bey näherer Vergleichung mehrerer Exemplare zeigen sich aber nicht nur am Hauptstamm befindliche, zum Theil schuppenartig aufliegende Blätter, sondern auch ausser denen zu beyden Seiten des hauptstamms vorhandenen Zweigen, noch andere, welche neben den letzten nach verschiedenen Richtungen auszulaufen scheinen, und es wird daher sehr wahrscheinlich, dass dieser Abdruck gleichfalls einem baumartigen Lycopodium angehört.

Lycopodiolithes piniformis

nomenclatorial act:
protologue/first publication
Page:
415
diagnosis:

Da die Ahbildung T. XXIII. fig. 1. a. b. eine treue Darstellung dieses Lycopodiolithen liefert, so macht sich eine ausführliche Beschreibung überflüssig. Er zeigt zuweilen eine entfernte Ähnlichkeit mit jungen Trieben von Schwarzholz, und hat daher seinen Namen erhalten. Fig. a. scheint ein Hauptast oder Stamm, und fig. b. vielleicht die Endspitze eines noch sehr jungen Exemplars zu seyn. Ob alle auf T. XXIII. fig. 1. 2. und T. XXV. f. 2. abgebildeten Zweige und Seitenäste zu dieser Art, oder zum Theil zu Lycopod.
