D. arcturi
A: The species that do not fit into my previous FAQ pages are all listed here. And what a mixed
bag they are! Some comments on them follow.
The three species, D. adelae, D. prolifera, and D. schizandra
are frequently called the "Queensland sundews". In the previous sentence, they are listed not only alphabetically, but
also in order of easiest
to hardest to cultivate. Drosera prolifera is particularly cool in producing plantlets on
its flower stalks, much like a strawberry plant.
The two species Drosera stenopetala and D. arcturi are temperates, and enter
dormancy during the winter. A particularly robust form of D. arcturi
occurs in Tasmania.
The two Australasian weirdos Drosera banksii and
Drosera subtilis are both probably very closely related to each other. They both look
rather like tiny erect tuberous Drosera. Currently they are classified in sections of the
genus Drosera that everyone agrees are probably wrong. Namely,
Drosera banksii is classified in the
petiolaris-complex, and annual Drosera subtilis is hanging out among the
tuberous Drosera.
Drosera binata is the great fork-leafed sundew.
(Drosera binata var. binata) is often called the T-form, and denotes
plants with mostly one bifurcation and deep green foliage that becomes red-tinged with age. A form with similarly
colored foliage but with approximately 8-16 leaf tips is called
D. binata f. multifida. An undescribed plant, similar to
D. binata f. multifida but with 16-40+ leaf tips is sometimes called
"D. binata f. extrema", a name seriously in need of validation.
The name
Drosera binata var. dichotoma indicates plants with yellow-green foliage
that regularly divides into four (or occasionally a few more) branches. Horticulturists have a selection of this called
Drosera binata 'Giant'.
A noteworthy Drosera binata cultivar is Drosera 'Marston Dragon'.
Drosera burmannii and D. glanduligera are known for their extremely
fast tentacle action. The marginal tentacles of D. burmannii can move 180° in a matter of tens
of seconds or even less, transporting or pushing bewildered insects into the middle of the leaf. Meanwhile,
D. glanduligera marginal tentacles flex so rapidly as to nearly catapult prey into the middle
of the trap!
Drosera hamiltonii is a very nice species with flat leaves that unroll like a carpet. This species
is easy to maintain, but a little tricky to grow well. It flowers gorgeously, but only if provided with a chilly winter.
It is easily propagated by root cuttings.
Drosera hartmeyerorum is closely related to D. indica, and may or not
truly be a distinct species. It was catapulted to fame when it was discovered to be festooned with small, yellow globules
of as-yet-unknown function. Other plants from the
Drosera hartmeyerorum-D. indica group have strange, non-glandular
emergences on the leaves, and it is not known if these are new species, or intermediate forms.
Drosera spatulata is a widely occurring species with many variant colors and sizes, many of which are
quite lovely. It is likely that in time, some of these will be split into separate species. The plant noted on many growers'
inventories as "var. lovellae" is a name that has never been established but should be, if only
as a cultivar. The Japanese Drosera 'Kanto', the very dark red
Drosera 'Ruby Slippers', and the large Drosera 'Tamlin'
are all cultivars of Drosera spatulata.
Drosera tokaiensis is a species of hybrid origin, that is
D. rotundifolia×D. spatulata. It is also referred to by the
horticultural cultivar name, Drosera 'Kansai', or sometimes with a symbol indicating its
hybrid parentage, i.e. Drosera × tokaiensis. This is similar to another entity of
hybrid origin, Drosera × nagamotoi. In this latter case, the entity is entirely of
horticultural origin, i.e.
Drosera × nagamotoi=D. anglica × spatulata.
