1212 A couple of hours' H erborization at Aden. [Dec. 



Petala 4, basi squama cupuliformi nectarifera instructa rubiscentia 

 extus glandtilosa, 2 majora. Stam. 4 ; Stigma tubulosum roseum, 

 Sepala subsequalia. Flores axillares solitares. Siliquse ellipticse acuta? 

 (nee oblongae ut in D. C.) Semina glabra ; variat petiolis longioribus, 

 foliis minus hirsutis, petalisque tantum 2 majoribus nectariferis. 



Cleome gracilis, nov. sp : herbacea, erecta, rigide ramosa 

 strigoso-hirsuta, foliis alternis, suboppositisve breviter petiolatis late 

 cordato-ovatis, orbiculatisve strigosis, racemis terminalibus aphyllis, 

 floribus gracile pedicellatis, sepalis 4, subsequalibus aeutis glandulosis, 

 petalis 4, cruciatis venosis lilacinis. Stam. didynamis siliquis sessilibus 

 flliformibus erectis, seminibus glabris. Habitu floribusque lilacinis 

 cruciatis cardaminem mentiat, ideo C. scaposse affinis? 



Cleome rtjta, Jacquemont — De Caisue p. 19, t. 19. 



This I believe to be identical with C. brachycarpa, D. C. (Ornitliopo- 

 doides, Forsk.) The description given by Forskahl is "perfectly similar ; 

 except that the old shoots do not become glabrous ; I only hesitate to 

 name it so, as I presume that M. DeCaisne had the opportunity of 

 comparing Jacquemont' s specimens with original ones of Vahl or 

 Forskahl. The Aden plant is certainly identical with that from the 

 Sutlej, with which I have compared it. 



Cleome muricata. — Erecta glabra apice glandulis nigris punctata, 

 foliis longe petiolatis palmatim 5-7-natis petiolis muricatis foliolis 

 petiolulatis linearibus utrinque aeutis apiculatis glaucis glabris, racemis 

 terminalibus thyrsoideis, sepalis glandulosis, petalis unilateralibus, duo- 

 bus (inferioribus) duplo majoribus longe unguiculatis 2 ovalibus ungue 

 brevi tubuloso nectarifero. Stam. 6 didynamis, stigmate sepili tubulo- 

 so extus annulo glandularum purpureo instricto legumine stipitato 

 (stipite pedicello paullo breviore) longo tereti acuminato polyspermo, 

 seminibus globosis tomentosis. 



This appears to differ from Forskahl's No. 120, C. angustifolia in the 

 downy seeds. And the leaves which could scarcely be temredJll?for?n. 

 Can it be C. paradoxa ? 



The flowers are very handsome deep, yellow veined with orange as 

 large as and rather resembling Cassia sophera. 



Cadaba monopetala. — Suffruticosa ramosissima ramulis juniori- 

 bus pilosis demum glabris tentibus, foliis subrotundis basi subcordatis 

 scabris margiue et petiolo hispidis, floribus axillaribus solitariis longe
