Observations: This slender species may be distinguished by its rigid, 
narrow, connivo-canaliculate laciniae, and minute marginal apothecia. Cer- 
tain more membranaceous examples of it approach the most completely nar- 
rowed states of R. Menziesii. It is not the same plant which was later cited by 
Swartz from Jamaica (FI. Ind. Occid. 3 : 1910. 1806) and. which, according to 
Nylander, is synonymous with sorediantha Nyl. Swartz’s description, cited 
above, adds the words “glomerulis terminalibus albis,” which do not seem ap- 
plicable to the present species. Dr. L. W. Riddle records the species from 
Jamaica. 
Ramalina canaliculata Tayl., New Lich., Hook. Journ. Bot. 6 : 188, 1847, 
was attributed to “California” as a type locality. 2 Except for the type speci- 
men preserved at Kew Gardens, London, I have seen no other material from our 
area, though the species seems to be almost synonymous with the preceding. 
It was defined as follows: “thallo caespitoso, glabro, nudo, subtus canaliculato, 
linearis, subdichotomo, albo-lutescenti, ramulis acuminatis; gemmis marginal- 
ibus, granulatis, statim spinuliformibus; apotheciis marginalibus, podicellatis, 
concavis, margine gemmis granulato.” It would seem to be identical with R. 
linearis f. spinulosa Merrill (Bryologist 11 : 50. 1908), and if deserving of 
recognition, no doubt should be called by Mr. Merrill’s name, as Taylor’s is pre- 
occupied; Fries’ canaliculata not being synonymous with calicaris L. Mr. Merrill 
remarks when describing his variety: “ R. canaliculata Tayl. is with difficulty 
separable from this species.”

Type: In the Nylander herbarium, Universitetets Botaniska Institution, 
Helsingfors, fide author. 
T^pe locality: “Mexico, Tampico, Uzul, 1838.” 
Original description: “Thallus stramineo-pallidus vel testaceo-pallidus, 
compressus, rigescens, linearis (altit. 3-5 centimetr., latit. 0.5-1. 5 millim.) et 
dichotome lineari-ramosus, canaliculatus, ramis divaricatis marginatis, laevis 
(passim obsolete longitudinaliter inaequalis), apicibus subfurcatis saepe glome- 
rulis sorediosis albis terminalibus; apothecia glauco-albida (latit. 3-6 millim.) 
concava, receptaculo infra sublaevis; sporae oblongae, leviter curvulae, longit. 
0.011-14 millim., crassit. 0.0035-0.0045 millim.” 1. c. 
Observations: Besides the type I have seen but a few other specimens 
of this p’ant from Jamaica and Santo Domingo. It is not always markedly 
canaliculate.
