and even attempted to get light from those of other institutions, E. tomentosum 
has not been found. 
Weddell compares E. longifolium with E. lineolatum Wight, and the narrow- 
leaved plant of Cuming’s collection does approach closely in habit to some 
collections of that species. Until now, there has been nothing here to match 
this narrow-leaved plant with any reasonable probability of identity. The want 
seems to be supplied by Bur. Sci. 13108 Foxworthy <£ Ramos, from Guinayangan, 
Tayabas, which has just about the appearance that an apparently immature 
plant such as that of Cuming might be expected to assume. Differences can 
easily be found; the stems are less pubescent, the longest leaf is 18 cm long 
but is little over 2 cm in width, the widest slightly exceeding 2.5 cm, and 
these longer leaves have more numerous teeth and veins, yet the leaves which 
have the same size as those of Cuming’s collection are practically identical 
with them in these and all other characters. The alliance suggested by habit 
is no longer with E. lineolatum Wight, but through intermediates in E. bana- 
haense and E. carinoi with E. sessile. Yet even between the three Philippine 
species, the stipules alone are sufficient for discrimination. These stipules are 
much in evidence on Bur. Sci. 13108; its staminate flowers are tetramerous. 
28a. Elatostema lutescens sp. nov. 
Herba succulenta, E. viridescenti Elmer similis, sed differt foliis multo 
'minoribus, latere angustiore magis dentatis, stipulis brevioribus, recep- 
taculorum staminiferorum bracteis minus corniculatis : receptaculis ses- 
silibus vel brevissime pedunculatis ; floribus staminiferis tetrameris. 
Staminate receptacles very shortly peduncled or sessile, completely 
inclosed beneath by the outer pair of bracts, the latter glabrous, in well- 
matured receptacles 3.5 mm long, 5 to 6 mm wide, broadly rounded at 
the apex, the spur thickened at its apex but barely projecting beyond 
the general outline of the bract; inner two pairs of bracts 2.5 mm long, 
3.5 mm wide, their margins broadly hyaline, the costa thick but not 
becoming free nor reaching the apex of the bract, glabrous ; bracteoles 
cuneate-oblanceolate, about 2.5 mm long: flowers on pedicels about 2.5 
mm long; perianth-segments 4, shortly and irregularly or not corniculate, 
1.5 mm long, the outer pair oblong-ovate, glabrous, the inner pair nar- 
rower, ciliolate at the apex; filaments about 1.5 mm long, anthers about 
1 mm long, the cells widely separated at the base: pistillate receptacles 
sessile ; outer pair of bracts ovate, 3 mm long, shortly corniculate, glabrous, 
free for rather more than half their length ; next two pairs lanceolate, 
2 mm long, corniculate, ciliate ; bracteoles narrowly oblanceolate, cuneate, 
1 to 1.5 mm long, long-ciliate toward apex; pedicels short; perianth- 
lobes rounded, about 0.2 mm long ; achene brown, becoming rather strongly 
ridged, about 0.6 mm long. 
Succulent or very succulent, 35 to 60 cm high, usually much branched; 
vegetative parts glabrous, definitely yellowish-green when fresh but losing 
this somewhat on drying : leaves very shortly petioled or subsessile, the 
lamina when dry submembranaceous, usually more or less falcate, lance- 
olate or narrowly elliptic, 3 to 7.5 cm long, 7 to 17 mm wide, or 
often still smaller, inequilateral, the base of the narrower side acute or
