Glossary

abscission
Shedding of a part of a plant (e.g. leaf flower) due to old age or stress.
bract
Reduced leaf often subtending flower or inflorescence.
cone
Term used here primarily to indicate the seed-bearing (female) structure of a conifer (‘conifer’ = ‘cone-producer’); otherwise known as a strobilus. A number of flowering plants produce cone-like seed-bearing structures including Betulaceae and Casuarinaceae.
exserted
Protruding; pushed out.
monospecific
(of a genus) Including only one species (as e.g. Aextoxicon).
morphology
The visible form of an organism.
peduncle
Stalk of inflorescence.
rachis
Central axis of an inflorescence cone or pinnate leaf.
spathulate
Spatula-shaped.

The monospecific genus Nothotsuga is closely related to Keteleeria and Pseudolarix, all three genera having terminally clustered male strobili and cones on long, leafy peduncles. In all three also, the seed scales are shed by disintegration of the rachis, rather than abscission of the individual scales as in Abies and Cedrus (Frankis 1988). Nothotsuga longibracteata was formerly classified as a species of Tsuga, and its vegetative morphology resembles that of Tsuga in many ways. It can be distinguished, however, by the presence of a long, leafy peduncle on the female cone, by its clustered male strobili, and by the exserted, spathulate bract scales of the cone (Page 1988).
