erecto, inferiore declinato; stylo glabro latitudine filamenta aequanti; 
stigmate obscure bidentato; ovario ovato-acuminato, inserto in recep- 
taculo cupulato ; capsula elliptica basi ad stipam latam contracta, apice 
minute glandulifera ; seminibus suborbiculatis minutissime muriculatis 
et palmate nervatis. —Duraneo: San Ramon, April-May, 1906, Dy, 
Edward Palmer, no. 73 (type, in hb. Gray). Dr. Palmer notes that 
is is a loosely branching plant 12-15 dm. high, with many scarlet 
flowers, growing at the edge of shady woods. It belongs to Sect. Sphen- 
ostegia Nees in DC. Prodr. xi. 479, and is near D. sewangularis Juss. 
and D.brachiata Spreng. The corolla in this is larger, with the lips 
less spreading. 
Tetramerium flavum, n.sp., caule erecto divaricate ramoso 6-12 dm. 
alto quadrangulato, inter angulos striato, scabridulo investo pilis tenul- 
bus adpressis et pilis articulatis longioribus; ramis oppositis, junioribus 
glandulosis et dense albo-pubescentibus ; foliis penninervatis ovato- 
acuminatis basi ad petiolum brevem inaequaliter attenuatis longissimis, 
in specimine viso 12cm. longis, 5 cm. latis ; petiolis 2 cm. longis ; spicis 
axillaribus et terminalibus simplicibus vel compositis (ultima splca 
longissima) ; floribus imbricatis, bracteis distichis oblanceolatis aristatis : 
trinerviis 5 mm. longis 1.5 mm. latis, apice recurvatis ; involueri brac- 
teolis connatis carinatis obovatis apice aristatis quinquenervatis 12 mm. 
longis, floram solitariam includentibus ; calycis laciniis lineari-setacels 
glandulifero-pilosis membranaceis 3mm. longis; corollae flavae tubo 
anguste cylindrico 4 mm. longo, laciniis patenti-divaricatis 1 em. longis, 
labio superiore erecto spatulato 1 cm. longo, inferiore ternato, segments 
patenti-divaricatis obovatis 1 cm. longis ; filamentis faucibus inserts, 
glabris ; antherarum loculis parallelis paulo inaequalibus muticis con- 
junctis ; ovario crasso-stipitato apice hispido breve acuminato 
lacinias superanti; receptaculo crasso clavato; stylo bifido antheras 
superanti.— Duranco: San Ramon, April-May, 1906, Dr. Ed 
Palmer, no. 75 (type, in hb. Gray). This is most closely related to 
T. aureum Rose, which, however, has bracts and bracteoles obovate 
obtuse, leaves truncate or subcordate at base. From all other species # 
differs in having the cauline bracts narrower and much shorter than the 
involueral. It is a showy plant, rather woody, growing at base of mour 
tains near the edge of woods. It is a free bloomer with “canary 
yellow flowers that close at night.”
