BLEPHAROSTOMA 141 
than the ventral, axile cells 1—6-seriate; root-hairs very long, color- 
less or yellowish, usually wanting, springing, when present, singly 
ог in groups of 2 or 3 from near the places of insertion of the 
underleaves : leaves rather widely spaced, patent or erecto-patent, 
divided nearly or quite to the base into 2 or 3 capillary laciniae 
(very rarely four, or in attenuate conditions sometimes reduced to 
one), the laciniae .36-.75 mm. (6-11 cells) long, often once forked 
at about the middle or above, discrete to the very base or more 
commonly connate for 1/-1 the height of the basal cells, slightly 
contracted at the septa; leaf-cells mostly 50-112 4 x 25-50 м, 
135-4 times as long as broad, hyaline, thin-walled, the septa some- 
times slightly thickened toward the periphery but never at all 
protuberant; cuticle (of the cortical cells as well) minutely 
striatulate: underleaves very similar in all respects to the lateral 
leaves: gemmae frequent, especially toward the stem-apex, uni- 
cellular, oblate-ellipsoidal, 25 и in greatest diameter, formed by the 
multiplication in a single series and reduction in length of the ter- 
minal cells of the leaf-segments, the resulting submoniliform 
chains composed often of 12-18 cells: remaining parts unknown.

The above species is strikingly distinct from Blepharostoma 
Фтећорћу ит. Llepharostoma | sejunctum * Angst., from Brazil, 
is doubtless a nearer ally, judging from description alone, but 
the Californian plant evidently differs from this in the shorter and 
rather stouter stems, in having often 3 leaf-laciniae, the basal cells 
of which are commonly more or less connate, in the broader leaf- 
cells, and probably also in the ramification. In habit and delicacy 
of structure, Blepharostoma arachnoideum is suggestive of Dr. 
Spruce’s genera 7z/aramea and Arachniopsis. The occasional oc- 
curence of a postical branch is an aberrant character in Blepharo- 
stoma, with which genus, however, the equally developed three 
ranks of leaves plainly unite our plant. The species, in a sense, 
connects Blepharostoma with Telaranea, which, in turn, as Spruce 
remarks, is with difficulty kept separate from Lepidozta.
