1.— A. Pillansii, N. S. Br. in Gard. Chron. , 1927, Vol. 

 IXXXI, 12 and Journ. Bot. 1928, 158. (See ^'igs. 110 and 111 and 

 112). — Annual, 4-5 inches high, glabrous on all parts except the 

 filaments of the stamens, central stem short, with 8-10 pairs of 

 leaves, internodes very short at the base and -g-l inch long at the 

 upper part, most or all of the leaves producing procumbent or as- 

 cending axillarj'' branches up to 6 or 8 inches long, with internodes 

 up to 1^ inch long. Leaves opposite, petiolate, spethulate, on 

 young plpnts arranged in 4 vertical ranks on the central stem, 

 withering and disappearing as the plant ages, at first erect and 

 with a tendency to turn themselves edgeways to the sky, becoming 

 more or less spreading; petiole i-li inch long, channelled at the 

 urper part, sheathing but not united at the base; blade 1-2 inches 

 long, 5-13 lines broed, elliptic to lanceolate, acute or subactue, 

 taT5ering into the petiole, entire, flat or more or less concave 

 and on young T>lants often v/ith the uper part more or less incurved 

 and so resembling shallow spoons, becoming flat on flowering plants, 

 thinly fleshy in substance, flowering plants smooth and cool to 

 the touch, uniformly green, not glaucous, without dots, glabrous. 



Flov.'ers terminal, often 3 on each lateral branch, developing 

 successively. Pedicels 2-4 inches long, about 1 line thick at the 

 base, slightly tapering upvrards, vithout bracts, smooth. Calyx un- 

 equally 5-lobes, with the tinited part shortly produced in a flat- 

 tened (not cup-like* manner beyohd its union with the ovary, where 

 it is sha Slowly hemispherical and about li- line deep, and has 5 

 small and rather indistinct angles alternating with the lobes 

 at their base, smooth, green; lobes narrowly spthulae from a broad, 

 ovate base, two of the lobes 6-7 lines long, the others shorter, 

 the 3 inner with broad membranous, fuscous margins. Corolla 16- 

 22 lines in diameter, expanding between 1 and 3 p.m., and closing 

 between 5 and 6 p.m., in dull or sunny weather, slightly scented; 

 petals very numerous in about 5 series, the outermost recurved, 

 the others widely spreading, rather loose and not closely overlapping 

 one another when fully expanded in bright sunshine, the outer 8-9 

 lines long and the inner 5-6 lines long, ^-4, line broad, linear, 

 very acute, bright lemon-yellow shading into white at the base. 

 Staminodes numerous, the outer narrov'ly petaloid at the basal part 

 gradually passing into petals; the inner hair-like, curly, v\^itish, 

 and at first connivent over the stamens. Style nearly 1 line long, 

 stout. Stigmas 10-12, about • line long, filiform (not plumose), 

 radiating, creamy white. Oyary flat on the top, 10il2 celled; 

 cells with 5-7 ovules in each. CapsiiLe as described under the genus, 

 7 lines in diameter when closed, shallow, flattish above, slightly
