 overtopping the stamens, 2-2^ lines long, at first closely pressed 

 together into a tapering column, but when the pollen is shed and 

 the petals begin to wither they separate and are slightly spreading

 This species is commonly cultivated under the name of J^'^esem- 

 bryanthemum rostrstum^ for which it Tvas mistaken by '^'alm Wck and 

 subseciuent authors, ^^t it is readily distinguished from the true 

 C. rostra t? by its much more slender leaves, that are more consnicu- 

 ously dotted all over, and particularly by the dots being more or 

 less prominent on som^ o" the leaves, from v/hich character ^^iller 

 gave it to the name of ^I. tuberculatum. 



C, ventricosa N, E. By^ — Plant forming clumps with branches 

 3-18 lines long arising from the top of a firm rootstock. Each 

 branch bearing a single growth v/ith 1-2 pairs of leaves, and often 

 v/ith branchlets in the axils of the outer pair, and clothed at the 

 base with 3-4 large, dry, chestnut-brovjn sheath 6-9 lines long; and 

 7-10 lines in diajneter, the remains of previous growths. Outer 

 leaves ascending or spreading and the inner pair ereCt with their 

 flat faces closed together for a period; li--3 lines long, 6-7 lines 

 bropd and 5-6 lines thick at the besal part, where they are united 

 into a sheath 5-9 lines long, flat or very slightly convex above, 

 obtusely keeled on the back, gradually tapering from the base to an 

 acute or subacute apexJ surface somewhat harshly velvety to the touch, 

 being densely covered with microscopis points visible under a lens, 

 glaucous-green or ^'hitish-green. Peduncles 9-£4 lines long, 1- 

 flov;ered, bracteate at the middle. Bracts with the free part 6-10 

 lines long, united below into a ventricose or swollen sheath, harshly 

 velvety like the leaves. Cfilyx unequally 5-lobed; lobes 6-9 lines 

 long, linear-lanceolate, acute or apiculete, three of them with 

 narrow, membranous margins. Petals in 3-4 series, 7-12 lines long, 

 1-2 lines broad, spathulate and acute or linesr-spathulate and 

 acuminate, rosy-nurple, striped with purple tovjards the base. Staraens 

 subdiffuse or the inner incurved, 2^-5 lines long, filaments not 

 bearded, rosy; anthers yellovi. ^isk annular, crenulete. Stigjnas 

 4-6, about if line long, broadly subulate, abruptly apiculete- 

 acumlnate. ^var:/' convex at the top, Copsule when closed 4^-6 

 lines in diameter, shortly and broadly obconic, flattish and va th 

 4-6 ridges about l|- line high on the top, glabrous, hard and rigid, 

 greyish, vrith 4-6 valves and cells 5 when expanded 8-9 lines in 

 diameter; valves about 2-2^ lines long and 3-3§ lines broed, broadly 

 deltoid, spreading horizontally, v/ith the expanding-keels much 

 shorter than the valve, y:idely separated throughout their length, 

 being ^ line apart at the base, thence diverging, straight, acute, 

 without membranous wings, chestnut-bro^\Ti; cells acutely roofed with 

 rather stiff brown cell-wings^ and with a large whitish tubercule 

 nearly closing the opening, ■^eeds not numerous in each cell, rather 

 large, about 3/4 line long, compressed, ovaoid, with a point at one 

 end, smooth, light brown.
