Crinum Capense.

[penciled words illeg]

Plant with extremely long, trailing much attenuated leaves, with their upper parts hanging down vertically parallel with lower & broader & upright part, with broad arch where bowing occurs, whether geotropism or mere weight cause bowing I know not [sketch]

One young leaf with apex a very little declined from vertical observed by means of triangles on curved straw filament & one with long depending arms observed with mark behind

Length of longest leaf on plant 53 inches: Breadth at base only 1.4 inches

The leaves Bow over at first bow over at about at a foot fr above the ground but afterwards bend lower down. (The Bowed leaf which was traced stood up vertically to cr crown of bow 20 inches & the tapering dependent part which part depended vertically from cr crown of arch was was only 5 1/2 inches.

The bowed leaf was observed by plant placed under Bell-glass with black dot on opposite side & depending tip was brought into lines with the dot & tracing then made moderately magnified. (see Tracing I.) on the first whole day (May 22d) it moved to one left side in zig-zag line, so that very long almost horizontal line was traced on glass. This probably due to plant recovering from disturbance & only the part fastened late in evening is shown in Tracing. During night continued same course to the left, but on early by 7º a.m on morning of 23d reversed course & went to right & so continued till 10º 30' when it rose the line rose & travelled back in former direction ie to left till 9º P.m when it travelled

moved to right & so continued all night. At 7º 6. 45' a.m on 24th moved down & to right till 9º 30 when it rose & moved to left; it then zig-zagged much rising. At night moved to right & next morning between 6º 40' & 10' 15 moved back to left.

There can be no doubt circumnutates. It will be seen that the dotted lines

A younger leaf which stood vertically up was observed under same Bell-glass— from 3º P.m on 22d of May to 10º 15' a.m. on 25th.

A fine glass filament was fixed obliquely on tip with 2 little paper triangle & tra movement traced on glass— Tracing II. considerably magnified

The line rose obliquely & this is due to growth of leaf.; but one if there had been no rising there wd have been 2 ellipses formed, & it appears that apex circumnutate about once in 24º.
