VP THE ABOR EXPEDITION , 1911-1912. 
m 
Seta 1 ‘5 — 2 cm. longa, tenuis ; calyptra angusta., pallide strain inea, 
nitida ; theca (immatura) cylindrica, leniter curvata vei suberecta, 
oporculo conico obtuso pallido. Cetera ignota. 
Ilab. On tree trunk, Rotung, alt. 1,000 ft., Abor District, 26th 
December 1911 ; leg. Burkill (n. 37514). 
A distinct species, and in some respects of somewhat anomalous 
position. In the branching and foliation it more closely resembles some 
species of Pseudoleskea ; the capsule, however, though immature, claims 
it undoubtedly I think for Leskea ; the calvptra and lid, etc.. beij<* 
almost exaetly those of L. poly car pa ; the curved, and occasionally e$ m 
arcuate form of the capsule is no doubt due to its unripe condition, 
and almost identical forms may be seen in unripe L. polycarpa. The 
straight, terete, rigid branches give it an unusual appearance, and will 
separate it from other species of the genus, and also from Lindbergia. 
7 a habit it is much like certain forms of Leskeella nervosa., but the 
inflorescence at once separates it from that. LesJcea pusilla Mitt., from 
Japan, must be quite different from our plant, judging from the soir 
what brief description. 
26* Claopodium Ren. & Card. 
32. Claopodium crispulum Broth, forma. 
Syn. Pseudoleskea crispula Bry. jav. 
On tree trunks, Kobo, c. fr. immatur. (n. 35939, 37070). 
A very interesting extension of the range of this plant, hitherto only 
known from Java and Formosa. It differs from the figures given in the 
Bry. jav. in having the branch-leaves gradually shorter-pointed as they 
pass upwards on the branch, the uppermost ones being quite obtuse. 
I find however that Javanese specimens (leg. Teysmann, in II h. Hampe, 
in Hb. Mus. Brit.) show the upper branch-leaves decidedly subobtuse 
thus forming an intermediate link with the Abor plant, which must 
be considered a form only. 
27. Thuidium Schpr. 
33. Thuidium trachypodum Bry, jav. 
Syn. Leskea trachypoda Mitt. Muse. Ind. or p. 133. 
On living trunk of tree, Kobo, c. fr. (n. 35954). On rock alt 
800 ft., mouth of the stream north of Peak, c. fr. (». 36U38). Above 
the mouth of the Serpo river, alt. 1,800 ft., c. fr. (with n. 37319). 
34. Thuidium cymbifolium Dz. & Mb. 
On fallen log, hills south of Rotung, ait. 4,400 ft., st. (n. 36236).
