Tropæolum elegans tricolorum. Dec. 6th 63.
In Hothouse
Thin shoot from bulb, without leaves, twined round stick & moved reverse of watch, in Hothouse
10°. 14' to 11°. 32' = 1°. 18' (very near not certain)
1°. 53' to 3. 15' = 1° 22'
― to 4°. 45' = 1°. 30' (third circle)
Stem excessively thin, like thick Bristle naked but here & there lateral fibres, coloured like stem. — Either branches or peduncle of leaves with leaf not developed—
These tendril-like bodies are sensitive to touch & yet straight again, & clasp stick, slightly enlarged at tip see William
Dec. 8th. one of these tendrils has caught new stick. —
The lower tendrils die off & drop without expanding when plant old & secure. Plant certainly twines; not so well as proper climber, because caught at intervals by tendrils.— Now, (Jan 25') leaves are beginning to develop; but I much suspect heat has prevented leaves developing— Leaves according to Lenny has independent movements;— the stem being fixed above & below by tendrils — Leonard found a peduncle which completed circle in 6'— must have moved much quick— Two methods of ascent L. saw movement in 3'.—
