BONATI—PHTHEIROSPERMUM AND PEDICULARIS. 107 
Maxim., but very different in the calyx ; it differs otherwise dis- 
tinctly from that species in the form of its hood; two staminal 
filaments alone are hairy in P. humilis, Bonati. 
Pedicularis dolichantha, Bonati. Sp. nov. (Longiflorae). 
Planta perennis. Rhizoma obliquum elongatum, squamis 
linearibus brevibus et obtusis tectum, radicibus pinguibus elong- 
atis. Unicaulis. Caulis erectus, simplex, 15-30 cm. altus, fistu- 
losus, angulosus, paulo villosus. Folia radicalia caduca. Caul- 
inaria multa, alterna, villosa, petiolata, linearia vel oblonga, 
pinnatisecta vel profunde pinnatifida; 10-12 jugis lob- 
orum ovatorum vel triangulatorum acutidentatorum ; petiolis 
15-40 mm. longis stricte alatis ac margine ciliatis ; limbo pingue, 
25-60 mm. longo, circa 10 mm. lato; lobis 3-5 mm. longis, basi 
plus minusve decurrentibus. Bractere foliiformes, petiolulatae, 
villosissimae. Flores omnes axillares, pedunculati; inferiores 
valde sparsi; pedunculis gracilibus nigrescentibus _ erectis 
glabrescentibus circa 5 mm. longis. Calyx  elonga- 
tissimus, cylindricus, hirtus, antice profunde fissus circa 
12 mm. longus lobis semper duobus basi constrictis breviter peti- 
olulatis profunde palmatifidis, segmentis paucis plus minusve 
dentatis circa 3-5 mm. longis. Corolla rosea, tubo 30-40 mm. 
longo extus villoso cylindrico; galea glabra, in parte inferiore 
breviter basi contorta sicut in P. siphonantha, D. Don; in parte 
anteriore addita crista elongata, abrupte contracta in apicem 
filiformem sigmoideum circa 10 mm. longum summo haud bifi- 
dum ; labio inferiore margine ciliato lobo medio cucullato ovato-

The plant is near certain forms (Hookeriana) of P. stphonan- 
tha, D. Don. ‘The differences are :—(1) The hood is furnished 
with a crest which is prolonged under the base of the beak ; (2) 
the corolla tube is hairy on the outside; (3) the beak is sigmoid 
not bifid at the point; (4) the lower lip has a non-emarginate 
median lobe; (5) the calyx has lobes more deeply cut and always 
two in number. It approaches equally P. megalantha, D. Don 
of which it has the inflorescence and the small flowers. It is dis- 
tinguished however at a glance by its 2-lobed calyx.
