Duplicates of Elmer's undetermined Nas. 17689 and 18364/ recently 

 received from the Philippines hâve the young offshoots nearly exactlx agr- 

 eeing with a frangment of this species, occurriiih in the Buitenzorg Her- 

 barium, taken from the stérile and probably very young original spécimen. 

 They are distinguished as follows : Shoots creeping, between irregularly 

 pinnate and dichotomous, caespitose, the main stem slender, to '/2 mm. 

 thick, vellowish when dry, 2'/2 — 3 mm. broad including the latéral leaves; 

 ultimate branchlets 1 — 10 mm. long (exciuding the spikes), piliform, r/2 

 — 2 mm. broad. Leaves remote on both stem and branches; latéral leaves 

 Hearly orbicular or the smalles ones suboblong (i. e. very slightly elongated), 

 horizonta.ly spreading, subacute or subobtuse, sparingly or remotely and 

 very minutely serrulate, the base broadly rotundate to truncate-subcordate; 

 of the main stem to 1 '/z mm. long; of the branchlets smaller, ^'4—1 mm. long; 

 intermedial leaves erect, broadly ovate, narrowly long-acuminate, rather 

 cuspidate, remotely or sparingly and very minutely serrulate, the base 

 nearly rounded to broadly rounded; of the main stem about 1 mm. long; on 

 the branchlets shorter. Spikes solitary and terminal on the branchlets, toi 

 cm. long by 2 mm. broad, occasionally growing eut to new shoots; spore-
