Siphonidium. | SCROPHULARIACEAE. 845 
entire or deeply 3-lobed, 3-nerved, glabrous or olandular-pubescent. 
Flowers on short curved peduncles, erect. Corolla about 3-3 in. long when 
first expanded, but elongating as the flowering advances and often becoming 
9in. long, very many times longer than the small calyx. Capsule #5-§ In. 
long, very much broader than long.—Cheesem. Man. N.Z. Fl. (1906) 558.

There can be no doubt that this plant is identical with both Armstrong’s Siphon- 
idium and Wettstein’s Anagosperma ; and as Armstrong’s name is the oldest it must 
take precedence. , 
Family XCIV. GESNERIACEAE. 
Herbs or shrubs. Leaves generally opposite or whorled, simple, entire 
or toothed; stipules wanting. Flowers usually irregular, hermaphrodite, 
in axillary or terminal racemes or cymes, or solitary. Calyx inferior or 
semi-superior, 5-partite; segments valvate. Corolla gamopetalous, usually 
irregular; tube long or short; limb more or less oblique, lobes 4-5, 
imbricate. Stamens 2 or 4, inserted on the tube of the corolla; anthers 
2-celled. Ovary superior or more rarely inferior, l-celled; style linear ; 
stigma capitate or 2-lobed; ovules many, anatropous, on two opposite 
entire or bifid parietal placentas. Fruit capsular or berried, dehiscent or 
indehiscent. Seeds numerous, small; albumen present or absent; embryo 
straight. 
A tolerably large family, almost wholly confined to tropical regions, Genera 80 ; 
species under 1100. The family includes many handsome greenhouse plants, especially 
of the genera Gloxinia and Achimenes, but otherwise its economic properties are unim- 
portant. The single New Zeaiand genus is endemic. 
RHABDOTHAMNUS A. Cunn./F 3& 
A much-branched shrub; branches spreading, scabrid - pubescent. 
Leaves opposite. Flowers solitary, axillary. Calyx free, deeply 5-fid; 
lobes lanceolate, acuminate. Corolla-tube subcampanulate ; limb obscurely 
2-lipped; lobes 5, rounded, spreading, nearly equal. Stamens 4 with 
the rudiments of a fifth, inserted on the corolla-tube below the middle ; 
filaments long, linear, arched; anthers cohering at the apex in a cruciate 
manner; cells distinct, parallel. Dise small, obscure, annular. Ovary 
superior, ovoid; style filiform; stigma 2-lobed; ovules numerous, on 
thick and prominent 2-lobed placentas. Capsule ovoid, acuminate, cori- 
aceous, 2-valved; valves 2-fid, separating from the placentas. Seeds 
numerous, minute, ovoid. 
A monotypic genus confined to the North Island of New Zealand. It is closely 
allied to the New Caledonian Coronanthera and the Lord Howe Island Negria.
