Smilax aspera. var. 1 1/2 — 1 3/4 long Maculata April 30 /64/

Zigzag branches with spines at right angles or slightly deflected downwards; one wd have thought sufficient.—

Does not bear tendril till grown some height. Tendril are situated on each side of leaf-peduncle near stem: are modified lateral leaflets. (Aug. St. Hilaire. —)

Are thin, are longer than leaf & peduncle are slightly curved & pointed at ends— Only Monocot, which I have seen with t. —

Last year towards end of growth, could see no sensitiveness whatever. Mem— — Gloriosa in this same respect & Eccremocarpus—

Now, on rubbing t. either side, curved sometimes afterwards to that side & recovered position —

I placed a thin stick in contact posteriorly

This plant was in Hot-house —

[25b]

in 1°. 20' had moved perceptibly; in 24° was at ∟' to own base;— in about 32°, the tip was curled curled round so as to be parallel to basis.— in 48° had wound entirely round stick.—

May 4th During 36° shoot moved no more than growth wd account for.— Tendril does not move spontaneously. —

May 14th The old tendrils which have passed backwards (this is a spontaneous movement) & have not yet curled round own stem are sensitive & will clasp stick. This sensitiveness endures long, after 2 pairs of t. alone have been fully developed.—

May 18th & 19th observed fine long shoot with Bell-glass— no movement of internodes.

[25bv]

Has less skill & energy than almost any other climber. — no Lathyrus aphaca less—
