allagophylla: tubers

Where's my lunch?

Tuber

Sinningia allagophylla, like the related S. curtiflora, makes secondary tubers on rhizomes (botanically speaking, these are stems, not roots, even though they are underground), as can be seen in this picture.  Presumably the extra tubers are both nutrient reserves and propagation devices.  They also provide a measure of security in case the primary tuber is destroyed.  These secondary tubers seem to appear at a fairly early stage, as this is a relatively young plant.

The idea for taking the photograph this way, as well as the inspiration for the caption, came from my 9 1/2 year old neighbor Erin Mittmann.  Who knows what she'll be coming up with by the time she is 10 1/2!





allagophylla: stem

Stem markings

This is one of the tall, sun-loving species.  My seedling has not bloomed yet, so this picture, showing red spots on the stem, will have to do for the moment.  These red markings are found on the stems of other species too, most notably Sinningia lineata.  Since S. lineata and S. allagophylla are not closely related, being in different subdivisions ("clades") of the genus, these stem markings do not appear to have taxonomic meaning, but it certainly is interesting that they appear in distinct branches of Sinningia, but not in (for instance) Nematanthus (as far as I know).

The page which discusses the incentives for a plant to make a tuber has a picture of S. allagophylla seedlings recovering from complete defoliation.

Publication

Sinningia allagophylla was first published (as a Gesneria) in 1829 by Carl Friedrich Phillip von Martius (1794-1868).  It was later the type species of Rechsteineria (1848).  Hans Wiehler transferred it to Sinningia in 1975.

Etymology: allago- ("different" ?) + -phyll ("leaf").
