348 JO URNAL, BOMB A Y NA TUBAL HISTOR Y SOCIETY, Vol IX. 



CALYX. — Inferior ; gamosepalous, tubular; herbaceous, covered 

 with stalked sticky scarlet glands throughout its length ; 5 — 10 

 ribbed ; often hyaline between the ribs. Mouth of the tube 

 funnel-shaped, scarious, very slightly 5-dentate. Limb not persistent ; 

 but more so than the corolla. Upper half bright red, often deep rose- 

 coloured ; lower half brown-red, with just a shade of green near 

 the insertion of the bracteoleg. The calyx is distinctly non-accrescent, 

 nearly always sessile. The pedicel if present is very short, oblong, 

 and deeply imbedded in the bracteoles. The calyx of young buds is 

 bright green ; the stipitate glands on it are also green. The viscid 

 mucus secreted by the stalked glands, or glandular hairs as some call 

 them, does not dry — (Boissier). Recent researches on these glands will 

 be referred to under the heading of Remarks later on. 



COROLLA. — Bright red, often deep rose-coloured ; hypogynous ; 

 hypocrateriform ; tube long, slender, slightly angulate, generally 

 lighter in colour than the lobes at its lower third. Lobes 5, patent, 

 sometimes equal, sometimes slightly unequal. The form of the indivi- 

 dual lobes varies much even in the same flower, being sometimes round, 

 sometimes obovate, but usually obcordate. The midrib of the petals 

 is distinctly paler and prominent on the under surface, ending some- 

 times in a sharp point. Hence Boissier calls the petals " unguiculate ;" 

 sometimes the petal is blunt at the apex, hence assuming the obovate 

 form ; sometimes it is distinctly notched, thus giving the petal an 

 obcordate appearance. The petals are sometimes faintly striate. 

 When fully open the corolla resembles that of the Jasmine. The 

 circumference of the expanded petals taken together is an inch or 

 even more. The corolla falls comparatively earlier than the calyx. 



STAMENS. — 5, opposite the petals ; free ; very fine and delicate ; 

 pale rose-coloured, partly whitish ; slightly rising above the " throat " 

 of the corolla-tube, and looking purplish. 



Filaments. — Filiform ; linear ; dilated at base and inserted at the 

 base of the petals " into the tops of the 5 nectarial scales " — (Rox- 

 burgh). 



Anthers. — Oblong ; introrse ; anther-cells separated at the base, 

 and opening by longitudinal slits. 



Pollen-grains. — Ovate. 



Hypogynous disk,— Absent.
