are suspended on the peduncles which increase in length during the 
maturing of the fruit. The latter is fifteen to twenty inches long 
and three to four inches thick. The resemblance of the fruit to a 
large sausage gave it the rather undignified name" Sausage Tree." 
Kigelia africana, as the specific name implies, is a native of 
Africa, especially of the western tropical coast of that continent. It 
has been in cultivation, however, in most tropical countries and has 
found its way also to Hawaii. 
As the tree is deciduous — that is, bare of leaves for a certain 
time during the year, it is not well adapted for street planting; an- 
other disadvantage is the dropping of the flowers shortly after their 
expansion. 
In Honolulu there are several of these trees; the largest and 
finest can be found in the Queen's Hospital grounds, while others 
are near the entrance in Air. Charles Atherton's grounds on King 
Street, and still others at Aloanalua Gardens and Kapiolani Park. 
Except for ornamental purposes the tree is of no economic value. 
When planted, however, it should be given plenty of room, as it is 
a spreading tree, developing a symmetrical crown. 
ACANTHACEAE 
The family Acanihaceae is represented by four genera out of 
the 204, which possess about 2000 species, all natives of tropical and 
warm regions. Besides Graptophyllum pictum, described below, 
there are in cultivation Thunbergia erecta ( Benth.) And., an erect 
glabrous shrub with a slender four-angled stem ; the white flowers 
are axillary and solitary; Thunbergia grandiflora ( Rottb. et Willd.) 
Roxb., a large, coarse, somewhat woody vine, with large, axillary 
flowers which may be solitary or arranged in long pendulous race- 
mes ; the corolla is of a pale blue ; it is a native of India. 
Barleria cristata L. is a much-branched shrub with violet flowers 
and two persistent green sepals, which are laciniately toothed. It is 
a native of India, and is usually grown as a hedge. It grows freely 
from cuttings. 
Sanchezia nobilis Hook., an erect shrub, is also cultivated ; it 
is a native of Ecuador. 
Of the family Scrophulariaceac, Russelia juncea Zucc, the Coral 
Flower, an erect, nearly leafless plant, with angled stem and bright 
red tubular flowers, is often planted on rockeries. It is a native of 
Mexico.
