Sept. 14 Clematis microphylla (var leptophylla)

This is an Australian sp: var young shoot in cool stove made € against sun in 2° 36'.— (omit this)

Young plant. The leaves are trifid, with each leaflet subdivided & with laminæ deeply cut — much like Calycina

Whilst young with laminæ or blades barely expanded each division of leaflet, terminates in sharp point, curved or hooked downwards so that they catch all each other & all minute objects like grapnels grapnels — This is owing more to downward curvature of leaflets itself than to that of the sub-petioles—

Points a little hardened. — As they grow old they become flat. —

Sept 18' Little hooked leaves not sensitive.— sub petioles sensitive to 1/8 & 1/16 loop of thread; but move slowly did move much in 24°. — Basal part of petiole, little or not at all sensitive; especially not fork between it & axis. —

[66v]

Clematis microphylla

Sept 18th Segment of leaflet much divided & curled very much round & pointed so as to serve as very efficient grapnel

Internode very long & thin —

[sketch] — This part long (Put after C. Viticella)

[sketch] Leaf

(Viticella type, but with all parts much smaller & leaflet divided as in C. calycina)
