IX. HYDROTRICHE. Zuccarim. 
TRIBUS GRATIOLEARUM. 
To Zuccarini’ llent description must 
be added: Capsula bivalvis, valvulis inte- 
gris medio septiferis, which appears to be 
the only character in which the genus 
differs from Dopatrium. The calyx is 
long, and tubular, often not cleft below the 
middle. The peduncles are reflexed after 
the flowering is over.

The genus Limosella, containing the L. 
59 
aquatica and L. capensis, appears to be- 
long to the Veronicee near Sibthorpia. 
Perhaps the Glossostigma would also be 
better placed there ; for, as in Sibthorpia 
and some of the annual Veronica, the dis- 
sepiment of the capsule does not appear 
to reach the top, even in the ovary. 
XI. 
TRIBUS BUDDLEIARUM. 
Noxia. Vent. 
Calyx brevis, campanulatus, regularis, 
4-dentatus vel 4-fidus. Corolla tubo bre- 
vi, limbo regulari 4-partito patente. Sta- 
mina 4, fauce inserta, equalia, exserta. 
Anthere distantes biloculares. Stylus 
simplex, stigmate integro incrassato. Cap- 
sula septicide bivalvis, valvulis bifidis sub- 
integrisve marginibus inflexis.—Frutices 
Austro-Africani sepe tomentosi. Folia 
opposita vel subverticillata, integra, sept- 
us dentata, Flores sepius sessiles glome- 
rulati, glomerulis sessilibus pedicellatisve, 
in paniculas terminales sepius dispositis. 
1. N. verticillata ( 
arborea, glaberrima, foliis subverticillatis 
petiolatis oblongo-ellipticis integerrimis, 
paniculis amplis fastigiatis, calycibus cam-

viter exsertis recurvis.

Has. Uitenhage district on the Zwart-

Cape collections. (v. s.) 
Very near N. verticillata, but the calyx 
is much more slender, flowers smaller, with 
longer stamina. Both species are near N 
saligna in habit, but with broader leaves, 
perfectly glabrous.
