11. The inflorescence is a scorpioid cyme and it is subtended by a boat-like spathe. 12. The inflorescences are subtended by showy bracts which can be ruby red to dark maroon or brown. 13. Each floret may be subtended by a bract, called a " palea " or " receptacular bract ". 14. Size and shape were determined by the visual angle subtended at the eye combined with perceived distance and orientation. 15. By the same argument, the maximum solid angle that can be subtended at any point is 4 sr. 16. The golden angle is then the angle subtended by the smaller arc of length " b ". 17. Some bicycle constructors refer to the angle subtended by the mechanical trail at the wheel centre as the caster. 18. Basically just remember that the arclength of a circle is the radius times the angle subtended at the centre. 19. Suppose, the line segment is subtended at an angle ? and has length " l ". 20. The umbels are subtended by noticeable spathe bracts, which are commonly fused and normally have around three veins.
