Glabra, calyculo triphyllo ad basin perianthii, scapo elato rigido 
remote bracteato, floribus spicatis, sepalis lineari-lanceolatis,

Has. Caraccas, Linden, April, 1842 n. 410; Andes of New 
Grenada, Linden (1842-3) n. 410. 
Radix e fibris crassiusculis, rigidis. Folia lineari-ensiformia, 
rigida, acuminata, 5-10 uncias longa, 3-4 lineas lata, pun- 
gentia, erecta, stricta vel subfaleata, pulcherrime profunde 
arcte striata, margine usque ad apicem incrassata, pubes- 
centia, basi equitantia, submembranacea. Scapus pedalis, fere 
sesquipedalis, basi crassiusculus, superne attenuatus, brac- 
teatus ; bracteis lanceolatis acuminatis, remotis, superioribus 
magis approximatis minoribus. Spica oblongo-ovalis, obtusa, 
14-16-flora. Flores approximati ut yidetur lutei, majusculi, 
omnino sessiles, bracteis tribus ovatis acuminatis calyculum 
referentibus basi stipati et bractea majore sub calyculum. 
Sepala 6, anguste lanceolata, obtusiuscula, striata, persisten- 
tia. Stamina 6, singulo ad basin cujusque sepali. F'la- 
menta subulata, glabra. Anthere ovate. Ovarium oblongum, 
8-loculare, loculis ut videtur e valvarum marginibus intro- 
flexis, marginibus seminiferis. ees: 
Nearly allied to Tofieldia frigida (which is surely identical 
with Isidrogalvia falcata, Ruiz and Pay. FI. Per. 3, p. 302, f. b.) 
but differing specifically in the greater size, in the truly sessile 
flowers, and in the thickened margin of the leaves. It is pro- 
bable, if we were to compare the ripened fruit of Isidrogalvia 
(R. and P.) with that of Tofieldia, we should find the former to be 
a distinct genus, as indicated by the larger, rigid, and pungent 
leaves, larger and coloured sepals, and general aspect. It is no 
doubt the representative of Tofieldia in the southern hemisphere.
