notes This image gives a view of an inflorescence axis as seen from above. Note, again, that all the 'floral units' on pedicels above the flowering one are in bud, and the higher up they are the less mature. Interestingly, there's also a nascent secondary inflorescence axis developing from the axil of the node just below the flowering pedicel (to right of center in the image). You can tell it's a nascent secondary inflorescence axis because, in addition to having the single basal bract, it also has small bracts developing further along the axis...each of which subtends (or will subtend) its own single 'pedicel+floral unit' on the secondary axis.
Note that the open flower here illustrates the irregular (zygomorphic) form of an 'inverted flower in standard position'. That is, the 2 corolla lobes of the 'upper lip' are held on the adaxial side of the flower (i.e. closer to the inflorescence axis); while the 3 lobes of the 'lower lip' are held on the abaxial side of the flower (i.e. further from the inflorescence axis). Thus the orientation of the flower here is 'well-behaved' with respect to this somewhat idealized botanical convention for describing an 'inverted flower' in Nemacladus. But often corollas will end up being positioned otherwise...so that the two lips do not conform to clear adaxial and abaxial positions. For example, pedicels may be slightly twisted, rotated, or convoluted due to vagaries of a plant's growth history and niche...arising from things like available space in the presence of other branches; patterns of lighting & shade; upward rather than outward positioning...and so on.
