5- Plagiochila Smallii Evans, Bull. Torrey Club 32: i8o. pi. 5, /. 1-8. 
1905- 
Collected in February, 19 18, at Las Ninfas, Cuba, by Brother Hioram 
(No. 2022); also in June, 1921, at Lake Cunningham, New Providence, Bahama 
Islands, by L. J. K. Brace. These specimens, which represent interesting ex- 
tentions of range, were both received from the New York Botanical Garden. The 
species was based on material collected b> J. K. Small and others in the southern 
part of Florida. It has since been found in various other localities in the same 
general region and has likewise been reported from Bermuda. It is the second 
species of Plagiochila to be recorded from the Bahama Islands. Its discovery 
in Cuba brings up again its relationship to the Cuban P. diffusa Steph., a species 
with which it was originally compared, and arouses the suspicion that the two 
species may be synonymous. The Cuban specimen, however, shows clearly 
the distinctive features of the species, and no connecting links between P. Smallii 
and P. diffusa have as yet been brought to light. 
6. Calypogeia acuta Steph. Bull. Herb. Boissier II. 8: 668 [Sp. Hepat. 
3: 400]. 1908. "Hab. America septentr. Pennsylvania (Rau)." 
A portion ot the type material of C. acuta, kindl> forwarded by Professor 
Chodat, gives the additional information that h was found at Bethehem in 1883. 
In his treatment of the genus Calypogeia Stephani arranges the species in tnree 
gioups characterized, respectively, by obtuse or truncate leaves, by acute leaves, 
and by bidentate leaves. The onl> North American species which he places 
in the second group is C. acuta, and he describes the cauline leaves of this specieo 
as 1.5 mm. long, crowded, spreading at a right angle, broadly ovate-triangular, 
and acute at the apex. The t>pe specimen shows that the last feature is by 
no means constant. Most of the leaves, especiall> on robust stems, are either 
rounded at the apex or very obtusely pointed. On some of the more slender 
axes acute leaves occasionally occur, but even here blunt leaves are in the majority. 
In the common C. Tnchomanis (L.) Corda a similar diversity in the leaf-apices 
is often encountered, and acute leaves ma> be even more numerous than blunt 
leaves on plants growing in unfavorable localities. The writer would therefore 
include C. acuta among the synonyms of C. Trichomanis, since the difference in 
the leaf-apices breaks down and since no other differences are brought out either 
by the original description or by the type material. 
7. Diplophyllum Andrewsii sp. nov. 
Collected on Jul> 8, 1919, on ground near Bee tree Creek, Buncombe County, 
North Carolina, by A. Le Roy Andrews (No. 117); also on July 31, 1919, on 
ground along roadside near Burbank, at foot of Roan Mountain, Tennsssee, by 
the same collector (No. 189)^ No. 117 may be designated the type. 
Yellowish or brownish green, sometimes becoming bleached with age, grow- 
ing in tufts or in small mats and. often mixed with other bryophytes: stems with 
ascending or suberect tips but prostrate and densely radiculose in the older parts 
* Andrews has already reported these specimens under the name "Diplophyllum Sp." See 
Bryologist 24: 52. 1921.
