Microcladia glandulosa Grev. (?). 



Among those algjo, which are rather common and abundant along 

 the pacific coast, there is a species of Microcladia, which appears to roe 

 after examination to be identical with Microcladia glandulosa Grev. 

 This species, however,- is not recorded, as far as I know, to occur in this 

 country, and as I have not yet seen any specimen of it, I have no small 

 difficulty in determining the plant in question. And so I think it better 

 to give here the description of our plant, and as the consequence of my 

 studying the minute structure of its frond, I would give some thought on 

 the systematic position of Microcladia and Carpoblepharis. 



Description: Fronds are linear, a ncipito- compressed, membranaceous, 

 and tufted, being erect or ascending from a shorter or longer decumbent 

 base, where the plant adheres to other alg«*e by emitting monosij>h<>iu>u>. 

 elongated and scutate root-fibres iV-m the uiidi-r-surfaiv. When the plant 

 is yet young, almost all of its under-Hirfaee adhere on the substratum: 

 but when old. the greater part is set free excepting a few basil porti"U«. 

 Tn full-grown fonds there is a more or less traceable stem or rachis which 

 (•ranches dichotoiiin-ahi-niately above in a distil hoir- manner. Lower branches 

 are longer than the upper with patent axils, and the plant is somewhat 

 corymbose in general ramilication. Hamuli are erect or erecto-patent, alter- 

 nately arising along both sides u f branches, and are many times diehotoroous. 

 sometimes assuming a flabellate appearence. Kamelli alternate toward the 

 apex or bifid with both arms slightly incurved when young, but becoming 

 usually patent when old.
