Bulbous and Tuberous Rooted Plants
A division of the Camden Park catalogues that is not clearly defined. Some of the more important families of the Hortus are included here, Amaryllidaceae, Iridaceae and Liliaceae. It also contains a wide assortment of other plants with a modified stem or root that acts as a storage organ. Such plants are usually deciduous and have a distinct dormancy period. Shrubs and trees are not included, but there is some overlap with herbaceous plants.
Sinningia speciosa ‘Rubra’
A cultivar of Sinningia speciosa (Lodd.) Hiern. The flowers of rubra are deep crimson red when first opened, growing paler with age, with a bluish tinge in the throat, and deeper shaded stripes on the tube. [FC p.98/1841].
Sinningia speciosa ‘Schaeferi’
A cultivar of Sinningia speciosa (Lodd.) Hiern, Gloxinia ‘Schaeferi’ is listed in the Appendix to the Gesneriad Register-Sinningia with a date of 1863, which would appear to be erroneous. No description is given. I have found no other reference.
Sinningia speciosa ‘Variegata’
Probably a cultivar of Sinningia speciosa (Lodd.) Hiern it has pale blue flowers and variegated leaves [JD]. This brief reference is the only description I have found.
Sinningia speciosa ‘Wortleyana’
Presumably a cultivar of Sinningia speciosa (Lodd.) Hiern but I have found no description.
Sinningia speciosa (Lodd.) Hiern
Frost-tender tuberous perennial with rosettes of scalloped dark green leaves, flushed red beneath, and solitary or clustered, nodding, tubular, bell-shaped purplish flowers in summer. To 30cm. A parent of most of the modern gloxinias, it was originally called Gloxinia speciosa by the English nurseryman Conrad Loddiges and modern cultivars occur in a large range of colours. [RHSE, Hortus].
Sinningia speciosa (Lodd.) Hiern (Lodd.) Hiern var. albiflora
Sinningia speciosa convariety speciosa (shortened to Sinningia speciosa here) is distinguished by slender, nodding flowers about 4cm long, solid white, violet or red, except for a band of yellow or white spotted with red inside the corolla tube. [RHSD]. The variety alba has white flowers.
Sinningia tubiflora Fritsch
Frost-tender tuberous perennial with leaves covered with fine white hairs, and fragrant, white, Nicotiana-like flowers borne on a one-sided raceme on erect stems, 60cm or more long. [Moore].
Sinningia x Cartoni Hort.
Edwards’ Botanical Register of 1844 reports the introduction of a number of new garden varieties of Gloxinia, including Gloxinia Cartoni, which is described as having deep pink flowers, the petals edged with white and with deeper pink stripes. The flower figured is a slipper gloxinia.
Sinningia x insignis Hort.
Insignis is figured in the Botanical Register, shown as white, flushed deep pink on the upper lobes and on the outside. It is a slipper gloxinia. [BR f.48/1844].
Sisyrinchium convolutum Nocca.
Frost-tender perennial with a creeping rootstock, linear to almost cylindrical leaves, basal fan of sword-shaped leaves, and a usually branched, winged stem, bearing up to 8 somewhat funnel-shaped yellow flowers with brown veining, to 1.5cm across. To 30cm. [RHSD, Hortus].
Sisyrinchium species unidentified
An unidentified species, no description.
Smithiantha zebrina ‘Splendens’
See Smithiantha zebrina Kuntze for details of the species. The cultivar ‘Splendens’ was seen at Kew Gardens and reported in the Floricultural Cabinet: ‘The flowers are more rich and brilliant, and the spotting deeper, and the velvet stripes of the leaves more distinct than the original species.’
Smithiantha zebrina (Paxton) Kuntze var. geroltiana (Kunth & Bouche) Voss
‘The flowers are green and yellow, beautifully freckled. Very interesting and blooms freely.’ [FC p.235/1846]. ‘Highly valuable plant for autumn and winter decoration. Long (2 feet) pyramidal-formed spikes, with numerous laterals of scarlet and yellow flowers. Similar to Gesnera zebrina.’ [FC p.6/1849].
Smithiantha zebrina Kuntze
Frost tender rhizomatous perennial with heart-shaped leaves, marked dark green or purple-brown along the veins, and scarlet and yellow flowers with red-spotted throats, in summer. To 75cm by 35cm. [RHSD, Hortus].
Sparaxis bulbifera (L.) Ker-Gawl.
Frost-hardy cormous perennial with up to 9 lance-shaped, ribbed leaves, to 30cm, and erect, dainty, rarely branched stems, with up to 6, white to yellowish cream, trumpet-shaped flowers in spring. [RHSD, Hortus, Grey].
