anthers into falcate acute upceurved teeth, and a short horn or tooth

Similar to 4. macrantha in coronal structure, but the habit, and the colour of 
the flowers are quite dist net. 
37. A. laurentiana, V. /’. Br. Stem herbaceous, erect, sparsely 
pubescent. Leaves sessile, up to 8} in. long and 10} lin. broad, lanceo- 
late, attenuate at the base, with hairs on both sides, revolute and 
scabrous along the margins. Umbels solitary or in pairs, terminal or 
lateral, 6-flowered ; peduncles as much as 63 in. long, but always shorter 
than the leaves from whose axils they arise; bracts 24 lin. long, lanceo- 
late; pedicels 15-16 lin. long, slightly hairy. Sepals 3 lin. long, ovate, 
acuminate, slightly hairy on the back. Corolla rotate; lobes 4 in. long, 
$ in. broad, elliptic, glabrous, yellow. Coronal-lobes arising a little 
above the base of the staminal-column, erect, 2-24 lin. long, complicate- 
cucullate, with the inflexed sides produced into small erect teeth, not. 
reaching to the same level as the rounded apex of the lobe, and with @ 
horn on the face within, arising a little below the middle of the lobe. 
Staminal-column 2 lin. long.—Stathmostelma laurentiana, Dewevre ip

38. A. rhacodes, V. #. Br. Stem 1-2 ft. high, erect, simple, 
rather slender, with a puberulous line down one side alternating at 
the nodes. Leaves somewhat ascending ; petiole 1—2 lin. long; blade 
3-4 in. long, 14-2 lin. broad, linear; gradually tapering to an acute 
apex, cuneately acute at the base, glabrous, with scaberulous margins 
and midrib. Umbels few (1-3), lateral and terminal, pedunculate, 
2-4-flowered ; peduncles #-1h in. long, puberulous along one side ; 
bracts 14-2 lin. long, linear or subulate, acute, very deciduous ; pedi- 
cels {—-1 in. long, puberulous. Sepals 2-3 lin. long, 1 lin. broad, 
lanceolate, acute or acuminate, puberulous or glabrous on the back. 
Corolla about 1 in. in diam., rotate (or somewhat reflexed 2), very 
deeply 5-lobed; lobes 54-6} lin. long, 21-24 lin. broad, oblong- 
lanceolate, subacute, glabrous on both sides, scarlet on the inner face, 
greenish, tinted with red and becoming yellow at the edges on the 
back. Coronal-lobes bright orange, arising 1-1} lin. above the — 
of the staminal-column and exceeding it by half their length, 3h-43 
lin. long, incurved-erect, narrowly complicate with ascending or sub- 
erect, falcate-ovate, acute, inflexed sides which much overtop the very 
obtuse apex, an upeurved subulate horn between them at the apex 
of the lobe. Staminal-column 24-31 lin. long; anther-appendages
