LXXXVII. SCROPHULARINEiE. 
16. BONNAYA. Link and Otto. 
(After — Bonnay, a German botanist.) 
Calyx divided to the base or nearly so into 5 narrow segments. Corolla 
tubular at the base, the upper lip erect, shortly 2-lobed, the lower larger, 
spreading, 3-lobed. Perfect stamens 2, included in the tube, the anthers 
cohering, with divaricate cells, the lower pair reduced to staminodia adnate to 
the throat, the ends either scarcely prominent or linear, entire obtuse and 
glandular. Style with 2 small flat stigmatic lobes. Capsule linear, longer 
than the calyx, opening in 2 entire valves parallel to the thin dissepiment. — 
Annuals usually glabrous. Leaves opposite. Flowers axillary or in terminal 
racemes, wuthout bracteoles. 
A small genus, spread over tropical and subtropical Asia. 
Stems diffuse, leafy. Staminodia free at the end, erect linear and obtuse 1. B. veronica/ olia. 
Stems erect. Leaves oblong-obtuse, sharply serrate 2. B. brachiata. 
1. B. veronicaefolia (Veronica-leaved), Spreng.; Benth in DC. Prod. x. 
421, and FI. Austr. iv. 498. A glabrous annual, much-branched, diffuse and 
rooting at the lower nodes, the flowering branches often ascending to Gin. or 
more. Leaves sessile or narrowed into a short stem-clasping petiole, oblong- 
lanceolate or almost linear, the lotver ones 1 to liin. long, entire or serrate, 
and often rather thick. Flowers in terminal racemes, on spreading stiff 
pedicels of 3 to 6 lines, which are usually angular and thickened upwards, the 
subtending floral leaves reduced to minute bracts. Calyx narrow, 1 to If line 
long, the segments sometimes united at the base. Corolla about twice as long 
as the calyx. Capsule linear, nearly ^in. long. — Wight, Ic. t. 1411 and 1412 ; 
B. vcrbenarfolia, Benth. in DC. Prod. x. 421, with the numerous synonyms given 
under both names ; Gratiola veronica/folia , Roxb. PI. Corom. t. 154 ; Lindernia 
veronici folia, F. v. M. Fragm. vi. 101. 
Hab.: Kockhampton, O'Slianesy. 
Common in tropical Asia, extending northwards to Loochoo. 
2. B. brachiata (brachiate), Link and Otto, lc. PI. Sel. i. 25 /. 11. An 
erect rather rigid, diffusely branched herb, 4 to lOin. high, branches decumbent. 
Leaves sessile, oblong obtuse or acute, deeply serrate with close sharp teeth, 
margins thickened, to liin. long. Racemes sometimes 4in. long. Flowers 
opposite, bracteate. Pedicels short, rigid. Corolla red or white, 3 lines long. 
Capsule )rin. long, slender, spreading or erect. — B. serrata, Griff.; Gratiola 
serrata, Roxb. FI. Ind. i. 139 ; B. brachiata and pusilla, Benth. Scroph. Ind. 32,

Hab.: Given as a Queensland plant in F. v. M. Ceus. Austr. PI. 
17. MICROCARP^A, R. Br. 
(Small fruit.) 
Calyx tubular, 5-angled, 5-toothed. Corolla with a short tube and 5 nearly 
equal lobes (the 2 upper more united, the lowest rather larger). Stamens 2 ; 
filaments filiform ; anthers 1-celled (by the confluence of 2 divaricate cells). 
Ovary completely 2-celled. Style short, dilated upwards into a broad spathulate 
lamina curved over the stamens. Capsule ovoid, included in the calyx, opening 
loculicidally in 2 entire valves, leaving the transverse dissepiment free. — Small 
creeping herb. Leaves opposite. Flowers very small, axillary, without 
bracteoles. 
The genus, as now constituted, is limited to the single Australian species, which extends into 
tropical Asia. If, however, the dehiscence of the capsule be neglected, it might include 
Peplidium. and even Glossostigma might be added as a section, differing chiefly in the calyx. —
