Corolla glabra; tubo absque squamulis denticulisve, ventricoso; limbovix longitudine tubi, laciniis conniventibus sinistrorsum imbricatis. Coronae foliola e basi dilatata adnata linearia, indivisa. Massae Pollinis (Pollinia) lineares.
OBS. Doubah was originally found by Sir T. Mitchell, but with fruit only, in one of his journeys, and also in his last expedition; and, according to him, the natives eat the seed-vessel entire, preferring it roasted. Captain Sturt, on the other hand, observes, that the natives of the districts where he found it, eat only the pulpy seed-vessel, rejecting the seeds.
16. JASMINUM lineare. Br. prodr. 1. p. 521.
Jasminum Mitchellii. Lindl. in Mitch. trop. Austr. p. 365.
OBS. In Captain Sturt's collection there are perfect specimens of this plant, on which a few remarks may be here introduced, chiefly referring to its very general existence in the sterile regions of the interior of Southern Australia, and even extending to the north-west eoast.
The species was established on specimens which I collected in 1802, in the sterile exposed tract at the head of Spencer's Gulf. With these I have compared and found identical Mr. A. Cunningham's specimens gathered in the vicinity of the Lachlan, in 1817; Captain Sturt's, in his earlier expeditions, from the Darling; those of Sir Thomas Mitchell, in his different journeys; and specimens collected in one of the islands of Dampier's Archipelago. In this great extent of range, it exactly agrees with a still more remarkable plant, and one much less likely to belong to a desert country, namely, Clianthus Dampieri.
I have considered Jasminum Mitchellii as hardly a variety of J. lineare, the character of this supposed species depending on its smooth leaves, and its axillary nearly sessile corymbi or fasciculi, which are much shorter than their subtending leaves; but even in the specimen contained in the collection presented to the British Museum by Sir Thomas Mitchell, the young branches, as well as the pedunculus and pedicelli, are covered with similar pubesceuce, and in the same degree as that of J. lineare; the specimens from Dampier's Archipelago have leaves equally smooth, but have the inflorescence of J. lineare; and I have specimens of J. lineare in which, with the usual pubescence of that species, the inflorescence is that of Mitchellii. Among Sir Thos. Mitchell's collection at the Museum, there is a Jasminum not noticed by Professor Lindley, which, though very nearly related to J. lineare, and possibly a variety only, may be distinguished by the following character.
Jasminum (micranthum) cinereo-pubescens, foliis ternatis; foliolis lanceato-linearibus, pedunculis axillaribus 1-3 floris, corollae laciniis obtusis dimidio tubi brevioribus.
