each side, somewhat acute above. Seeds each on the apex of a somewhat 
elongated funicle; funicle a little enlarged above, but not developed 
into a true retinaculum.—A shrub with rigid branches, arising regularly 
in pairs at each node, viscid-pubescent. Leaves narrow, sessile, scabrid. 
Flowers solitary in the axils, shortly pedunculate, ebracteolate. 
Endemic.

There is much doubt about the position of this plant. The mode of branching 
and the leaves are as in Hygrophila pilosa, Burkill, but there are characters in the 
ovary and in its shrubby nature which remove it; the ovary is more like that 
of Nelsonia, but the calyx, habit, and other characters are very unlike ; the stamens 
again are very different from those of the first tribes of the Acanthacee, and suggest 
a relationship to Blepharis, which can in no way be considered as close. On the 
other hand, the habit is that of Radamea in Scrophulariacee, and the stamens are 
like those of some plants of its affinity ; and, finally, the oblique capsule is like that of 
a Pedicularis or a Melampyrum and separates the genus so much from Acanthace@ 
that at first we were inclined to place it unhesitatingly in Scrophulariacee. The 
pollen is character!ess, and in this like that of Serophulariacea. 
Spencer Moore places Hiernia between Nelsonia and Hygrophila ; Lindau places 
it near Nedsonia ; while doubting if it really belongs to Acanthace@, we consider 
ont at least it ought to be placed ina tribe separate from the other plants of this 
rder. 
OrpdER XCIX. MYOPORINEZ (by R. A. Rolfe). 
Flowers hermaphrodite, irregular or nearly regular. Calyx inferior, 
5-partite or 5-lobed. Corolla gamopetalous; tube short and somewhat 
campanulate, or elongate and infundibular; limb subequal, oblique or 
bilabiate, 5-, or rarely 6-, !obed ; lobes imbricate, the two posticous often 
exterior, sometimes deeply connate. Stamens 4, didynamous or subequal, 
rarely as numerous as the corolla-lobes, inserted on the corolla and alter- 
nating with its lobes, included or exserted; filaments filiform or 
thickened at the base; anthers normally 2-celled; cells at first 
parallel, afterwards often diverging from the confluent apex, dehis- 
cing longitudinally. Dise hypogynous, small or nearly obsolete. Ovary 
superior, normally 2-celled, but often spuriously many-celled by the 
intrusion of septa between the ovules, or truly many-celled. Ovules 2, 
collateral, or 4-8 in superposed pairs, or solitary when the ovary 18 
many-celled; anatropous, with a superior micropyle; style simple, 
terminal, short or somewhat elongated, filiform ; stigma terminal, small, 
entire or obscurely emarginate, rarely oblique. Fruit drupaceous, indehis-
