This species is interesting as affording a good instance that the union or freedom

of the filaments of the lower pair of stamens is quite untenable as a generic. 
character, both Orthosiphen and Hemizygia being represented on the same plant. 
The specimen is now in the Herbarium of Dr. Bolus. 
27. 0. humilis (N. E. Br.) ; stems arising from a woody root- 
stock, erect, 7-10 in. high, thinly villous below, more densely so 
above, with 1-2 pairs of short flowerless ascending branches below 
and a paniculate inflorescence of 2-3 pairs of lateral racemes and 
a terminal one; leaves in 4 pairs, }~} in. or rather more in 
length, }-1 in. broad, lanceolate to elliptic, acute or obtuse, 
cuneately narrowed to a subsessile base in the leaves on the main 
stem and into a distinct petiole }—-2 lin. long on the lateral 
branches, entire, green and with very thinly scattered pubescence 
of minute adpressed hairs on both sides, with longer and more 
conspicuous hairs on the veins beneath, shortly ciliate; glands 
inconspicuous ; bracts 14—3 lin. long, 1-1? lin. broad, elliptic-ovate, 
acute or acuminate, with a few minute scattered adpressed hairs 
on the back, violet or dark bluish-purple, very deciduous or perhaps 
the uppermost persistent, but not very conspicuous ; pedicels 
1-1} lin. long, densely villous; calyx-tube } in. long, tubular- 
campanulate, villous outside, microscopically puberulous within ; 
upper tooth 2 lin. long and broad, suborbicular, not decurrent on 
the tube, violet ; lateral and lower teeth subequal, 1{-1} lin. jong, 
bristle-like from a deltoid base, ciliate ; corolla partly destroyed in 
the only two flowers seen; tube not or scarcely exceeding the 
calyx-teeth, 44-5 lin. long, dilated to about 2 lin. in vertical diam. 
at the subtruncate mouth, which forms the upper lip with a small 
transverse erect or reflexed lobe ‘at the apex having a small 
rounded tooth on each side of it, puberulous outside on the upper 
part ; lower lip about 24 lin. long, concave, apparently directed 
forwards, puberulous on the back ; stamens broken off in the flowers 
seen ; upper pair inserted at the middle of the corolla-tube, with 
free filaments ciliate at the lower part; lower pair evidently longer 
than the lower lip, with united filaments.
