paniculatus x wallichii ssp. wallichii

"The short round leaf scars on young stems, the terete leaves and short urceolate flowers with a tube 10 - 12 mm long resemble those of T. wallichii. The corolla is more or less glabrous unlike that of ssp. wallichii, which was the only other plant in the area. The sparsely branched, thick, smooth stems with peeling bark and the loosely branched inflorescences are reminiscent of T. paniculatus. The short urceolate flowers will distinguish this hybrid from the very similar T. cacalioides x T. paniculatusknown as T. x fergusoniae. (Tölken 1985)

The hybrid of T. paniculatus x T. wallichii has no name. 

Interestingly the curator of the Ruth Bancroft Garden claims to cultivate such a hybrid, labelled as "T. dinteri". However this name is a synonym of T. wallichii ssp. ecklonianus i.e. a synonym of a species and therefore cannot be used as name of a hybrid. Moreover his plant does not correspond to Tölken's description cited above and to the photos shown below of a deliberately produced hybrid of T. paniculatus x T. wallichii.


The plant wrongly named "T. dinteri" is common in California and known also in other parts of the world, all plants having the same source. According to the breeder all the plants are seed grown and they are true to their parents. This means the mysterious "T. dinteri" is a species and not a hybrid. Its resemblance to T. cacalioides in regard of the flower shape and colour and of the leaves is obvious, the only difference is in the stem lacking the characteristic phyllopodia. However Tölkens mentions also forms of T. cacalioides with smooth stems, so it may not be wrong to replace the impossible name "dinteri" by T. aff. cacalioides.

Note :

John Lavranos found the hybrid T. paniculatus x T. wallichii in the W Cape, Cape Winelands Distr., Mt. Fonteinskop, on the R356, 18 km NE of Karoopoort, in 1988 (his nr. 26739).
