EXACUM ROSULATUM, n. Sp. 
Annuum, erectum, glabrum, caule ramoso, foliis plerisque basalibus rosu- 
latis obovatis, caulinis paucijugis valde reductis, floribus in cymas plurimas 
paucifloras densas paniculatas dispositis, pedicellis brevissimis, calycis 
segmentis oblongis obtusis exalatis, corolla segmentis oblongis quam tubus 
3-4plo longioribus, antheris parvis oblongis filamento elongato. 
An erect annual, glabrous in all its parts, with slender stems 
under a foot long, branched low down. Leaves at the flowering 
time several in a basal rosette, obovate, membranous, glabrous, an 
inch long, narrowed from the middle to the base, and about three 
pairs on the stem sessile and much smaller. Flowers in several 
distant cymes on erecto-patent peduncles, very few in each, with 
very short pedicels; bracts small, thick, cblong. Calyx campa- 
nulate, 75 in. long, eut down nearly to the base into five oblong 
foliaceous segments, which are not at all winged on the back. 
Corolla bright yellow, 1 in. long, with a short tube and 5 oblong 
segments. Stamens inserted in the tube, reaching halfway up 
the corolla, with small oblong versatile anthers and filiform fila- 
ments,— Central Madagascar, Baron 1886 ! 
EXACUM SPATHULATUM, N. sp. 
Annuum, erectum, glabrum, caule simplici, foliis 5-6-jugis oppositis orbi- 
cularibus sessilibus, floribus paucis in cymas densas terminales aggregatis, 
pedicellis brevibus, bracteis oblongis, sepalis 5 oblongis exalatis, corolla 
segmentis oblongo-spathulatis tubum campanulatum triplo superantibus, 
antheris magnis lineari-oblongis filamento brevissimo. 
An erect annual, glabrous in all its parts, with slender simple 
stems 3-1 foot long. Leaves in about half a dozen Pa orbi- 
cular, sessile, membranous, the lower near together, 1-2 in. long, 
narrowed to the base or rounded, the upper distans and much 
smaller. Flowers 3-6 in dense simple or slightly compound ter- 
minal cy mes; pedicels very short; bracts small, ovate or oblong. 
Calyx campanulate, 3-+ in. long, oa to the base into five oblong 
green segments with a white margin, not at all winged on the 
back. Corolla bright yellow, 3-3 in. long, with a campanulate 
tube and 5 oblong spathulate segments. Stamens inserted in the 
corolla-tube, with a linear-oblong anther > in. long and very 
short filament. Ovary globose, with a curved style 4 in. long.— 
Central Madagascar, Baron 1857! This and the last are yellow- 
flowered annual species, with the habit of Exacum quinquenervium 
and Sebea brachyphylia and S. Bojeri.
