Parkinsonia. | XLVII. § CHSALPINIEH (OLIVER). 267 
pointed, the pinnz appearing as very long simpl pinnate geminate or 
fascicled leaves at first sight. Flowers in lax aetlary racemes, yellow ; 
bracts early caducous. 
A genus of three species, one Cape and two American. 
1.* P. aculeata, Linn.; DC. Prod. ii. 486. Coriaceous flattened 
rachis of the pinnw $—2 ft. long; leaflets frequently obsolete or minute, 
seldom more than }—-}in. long. Racemes shorter than the leaves. 
Flowers 4-1 in. in expansion. 
Not indigenous in Africa, though cultivated or naturalized in various localities. 
9. OLIGOSTEMON, Benth. et Hook. f. Gen. Plant. i. 570. 
Sepals 4 distinct, the outer anterior coriaceous, sheathing the pos- 
terior and larger in bud; inner sepal deeply 2-lobed, subpetaloid. 
Petals 5, much shorter than the outer sepals, 8 upper lanceolate-oblong 
colour-veined, 2 lower smaller glandular-denticulate. Stamens 4, de- 
curved ; filaments very short and flattened; anthers large, affixed 
immediately above the base, 2-celled, each cell deeply sulcate and ter- 
thinating in an acuminate tip, dehiscing longitudinally near the apex, 
2 posterior anthers connate nearly throughout. Ovary narrowed below, 
with 4 strong longitudinal ridges or wings, 2-ovulate; style subfili- 
form ; stigma small terminal. egume elongate, narrowed below, acu- 
minate, not seen mature.—Shrub or small tree. Leaves alternate 
imparipinnate ; leaflets petiolulate 5-9, rather large. Racemes erect, 
terminal, with numerous Alpinia-like flowers—Duparquetia, Baill. in 
Adansonia, vi. 189. 
Peculiar to West Tropical Africa. : 
M. Baillon, taking a different view of the structure of the flower, describes the calyx 
as diphyllous, consisting only of the outer posterior sepal and the opposed anterior 
contiguous one embraced by it; the 2 innerlobed sepals with the 3 posterior petals make 
up the corolla, while the anterior glandular reduced petals are described as _petaloid 
staminodia. Fertile stamens he describes as 8 in number, regarding each of the four 
2-celled anthers as double. 
1. O. pictus, Benth. in Trans. Linn. Soc. xxv. 305. t. 39. A shrub 
of 6-20 ft.; extremities and inflorescence at first rusty-puberulous. 
Leaflets usually 7—9, thinly coriaceous, obovate-elliptical or the lower 
broadly elliptical, rounded and shortly apiculate above, cuneate, or 
slightly rounded at the base, lateral nerves few, subremote, connected 
by somewhat, transverse reticulation, 4-6 in. long, 24-3in. broad, on 
petiolules of 1-}in. Racemes erect densely many-flowered, at length 
4-1 ft. long. Bracts minute, ovate-deltoid, deciduous. Pedicels ascend- 
ing or patent, puberulous }—1in. long, articulated a little above the 
base with a pair of minute bracteoles below the joint. Inner larger 
sepal 1-11 in. long. Anthers }in. long. Mature legumes not seen ; 
the most advanced in the Kew herbarium are 5 in. ong, and nearly 
4 in. broad above.—Duparquetia orchidacea, Baill. in Adans. vi. 190. t. 4.
