256 xxvii. tiliacejE (masters). [Trittmfetta. 



A very distinct and singular species, having, as Dr. Welwitsch remarks, more the habit of 

 a species of Relichrysum than of a Trinmfelta. The leaves, according to Dr. Welwitsch, 

 are not produced till after the flowers have fallen, hence, perhaps, the reason why in herbaria 

 leafless specimens are more abundant than those provided with leaves. 



4. T. geoides, Welw. mss. An erect herbaceous plant, giving off from 

 the summit of a woody stock numerous flowering and leafy branches about 

 a foot in height. Leafy shoots appearing after the flowers, cylindrical, 

 clothed with long simple villi. Stipules long, subulate. Leafstalks 1-3 in. 

 long. Leaves polymorphous, more or less cordate, roundish or angular, 

 obscurely lobed, sinuous or irregularly crenate and thickened at the margins, 

 palmately 5-7-nerved, veins very prominent, smooth or sparingly stellate- 

 pilose above, covered with close white down beneath ; 2-4 in. long, 1-3 in. 

 wide. Flowering-shoots similar to the preceding and appearing before them, 

 usually leafless and bearing a terminal, many-flowered, much-branched cyme. 

 Ultimate pedicels shorter than the flowers. Flower-buds obovoid, obtuse. 

 Flowers scarcely half an inch long. Sepals violet, oblong, obtuse, downy, 

 apex inflected. Petals golden-yellow, half the length of the sepals, tapering 

 to a ciliated stalk. Stamens 20. Disk ciliate, glandular. Fruit globose, 

 the size of a cherry, 4-valved; valves densely covered with long, slender, 

 pink, setose bristles each tipped with a tuft of fine white hairs. 



Lower Guinea. Angola, Br. Welwitsch ! 



A very curious and distinct species, when in fruit having much the appearance of a species 

 of Geum. 



5. T. annua, Linn. ; DC. Prod. i. 507. An annual with erect, slightly 

 pilose stems, 1-2 ft. in height. Leaves generally on very long stalks, ovate, 

 acuminate, dentate, 3-nerved, smooth or slightly pilose, 4-5 in. long, 2-4 in. 

 wide. Stipules subulate. Peduncles extra-axillary, 3-flowered, \ in. long. 

 Flowers 2-3 lines long. Petals bright orange, nearly as long as the apicu- 

 late sepals. Stamens 10. Fruit globose, the size of a pea, smooth, covered 

 with glaucous hooked prickles, 4-celled, 4-seeded. — T. Schimperi, Hochst.

Lower Guinea. Angola, Br. Welwitsch. 



A plant that varies in size, texture, and hairiness according to the locality in which it is 

 grown. Dr. Welwitsch's specimens have black dots on the stem and are of a more shrubby 

 habit ; a hairy line is often visible down one side of the stem. In spite of these and other 

 variations, the species may be readily known by its long leafstalks and fruit smooth betweeu 

 the prickles. 



6. T. semitriloba, Linn. ■ DC. Prod. i. 507. Suffrutescent or 

 shrubby, pubescent with stellate down or villose, upper surface of the leaves 

 sometimes nearly glabrous. Branches erect or spreading, covered with a 

 very tough bark. Lower leaves on long spreading stalks 1-4 in. long, 

 roundish, subcordate, 3-5 -lobed, lobes acute, central one longest, irregularly 

 toothed ; 4-6 in. long, 3-4 in. wide ; upper leaves smaller, oblong-lanceolate 

 or cordate-ovate, acute. Flowers numerous, in close cymose clusters ar- 

 ranged in long leafy racemes along the sides and ends of the branches. 

 Flower-buds oblong, apiculate. Sepals 5, oblong, apiculate. Petals oblong,
