Shoot development in C. fasciculata. Scanning electron micrographs of shoot tips isolated at different developmental stages. A to C, Twenty-four hours after imbibition. There are two leaf primordia at this stage. D, Four days after imbibition. Three leaf primordial have been initiated. E, Twenty-four days after imbibition. Eight leaf primorida have been initiated. There is very little axillary bud development. F, Thirty-three days after imbibition. Twelve leaves have been initiated. Axillary buds in nodes 6 and above are floral. G, Forty-nine days after imbibition. Fourteen leaf primordial have been initiated. Axillary buds are floral in nodes 5 and above. H, Fifty-four days after imbibition. Eighteen leaves have been initiated. Flower development is advanced in lower inflorescence axillaries. I and J, Ninety-two days after imbibition. Twenty-six leaves have been initiated. J, Floral axillary bud with the bract removed to expose the developing flowers. L, Leaf blade; S, stipule; R, radical; *, possible scalar leaf; TM or T, terminal meristem; T, terminal meristem; A, axillary bud; Br, bract (numbers following symbol indicate the node number).
